(a) Insuring Against the Presence of Oxygen in Equipment Being Returned to Sctrice Purging with Inert gas for reduction of oxygen content is usually more difficult Chan bp other methods. Inert gss is cosposed primarily of nitrogen Ad carbon dioxide but may contain traces of hydrogen, carbon monoxide, oxygen. Ad nitrogA oxides. Alternate pressuring Ad renting the vessel tostmospherlc pressure will reduce the oxygen content of the atmosphere -within It. After purging with inert gss, a sufficient ntmbcr of tests shall be made with A approved oxygen analyxer to give complete uiumce that a mixture is At presAt in the vessel which contains more thA 32 oxygen. Where hydrogen, hydrogen sulfide or carbon monoxide may be ptesAt, the 0^ cootAt should be reduced to no Are thA 22 dot to the wide explosive range of these gsses.

Special Problem* In Caa Testing Lons Pipe Lines. The foregoing requirements for gas testing are intended to be applied to work on or in pipe lines as well as larger vessels. Quite often, however, it is impractical to obtain gas tests at enough locations in a pipe line to assure a gas-free condition. The decision in each case Is to be made by the operating foreman baaed on his own judgment and that of the gas tester. The following general rules should be observed where practical: a. The section of line which is to be tested should be limited in length by blanking it off from adjoining sections. b. Caa tests should be obtained at the ends of the line section, st or close to the point where the hot work is to be per formed, st crapped sections (high or lew points), and at intermediate points every 100 - 200 feet throughout Che length of the line. c.

Groups Authorised to Conduct Gas Teats Gas teats shall be conducted only by qualified employees. The selection of qualified persons for conducting gas teats and the responsibility for Insuring that all of these employees are satisfac torily instructed shall rest with the beads of the laboratories and/or Process Divisions. 1. The process supervisor at the Karyland end Anchorage Tank Fanes Is authorised to sake all combustible gas tests st those tank farms. It is the responsibility of the process super visor to see that all requirements of this standard are met. It is alao bis responsi bility to have the gas detector checked for accuracy before and after each time that it is used. This cheeking will be done using the known mixture furnished by the Laboratory. It la the process supervisor's further responsibility to have the detector and the standard saaple inspected every 60 days by the Laboratory. The Laboratory should keep a record of these inspections and should notify the supervisor when inspections are overdue. When testa are required for toxic materials, the process supervisor is responsible for seeing that these tests are made by authorised personnel. 2. Oxygen tests made with a Beckman oxygen analyzer say be conducted by the operating personnel. It is the process supervisor's responsibility to see that (a) the testing device la main tained in proper working order, (b) the testa are conducted by only properly trained employees, and (c) the provisions of this standard are com plied with. 11A-5 E NO 04253 Gas Teatins Technltnxs 1. General The two instruments ccmaonly used for combustible gii testa are the MSA and the JW exploaInatera. The MSA sxplosimeter la calibrated with normal hexane and has a scale graduated In percent of the lower explosive limit.(l.e.l.). The JW exploslaetcr la calibrated on normal pentane and baa a acale graduated In decimal fractions of l.s.l. Tor example, a reading of 0.2 on the JW la equivalent to 20Z on the MSA. a. Zn testing for gases la an open area, the tester shall go over the entire area and ' make testa at frequent intervals to be assured that the entire area and lamedlate surroundings are free of combustible gas, b. In vessels gas teats should be conducted at all openings, whenever practicable. In the case of very large vessels such as bubble towers which have manholes or handholes located at very close Intervals, it say be necessary to remove only part of the cover plates to Insure a satisfactory test. c. In vessels that have been gss-freed by steam ing, or are above atmospheric temperature for any other reason, a sufficient cooling period shall have elapsed before the gas test is made so that the vapor temperatures approach that of the atmosphere. This requirement should prevail wherever gaa tests sre mads of any hot heavy oil vapora. Such vapors have a tendency to condense in the tubing of the combustible gss detector end give an erroneously low read ing. A portable combustible gaa alarm, avail able at the laboratories, may be used in the vessel to overcome delays in letting the equip ment cool. d. The latest threshold value for 1962 for gaso line vapor without respiratory protection is 500 parts per million (American Conference of Governmental Industrial Hygienists). For entry into a vessel which baa contained gasollna vapor, a reading leas than 0.0S of l.e.l. on the JW exploslmecer or 5Z on the MSA exploalmcter is required. For entry in the same vessel with 1M-6 EM00425 A alr-aupplled respiratory protection, the reed ing suet be below 0.5 of l.e.l. on the JU and 50X on the MSA exploslaeter. For hot work all readings Mist be sero. Combustible Gas Teats a. The ^combustible gas detector shall be cheeked . with a standard sample of hydrocarbon vapor to assure Its operability before leaving the laboratory and also after returning to the laboratory. This will assure that all tests made on a given trip are reliable. b. Combustible gas detectors are calibrated for pentane-air or hexane-air mixtures and read ings obtained with other combustible mix tures may be is error. Judgment must be used since only qualitative readings are required. c. The combustible gas detector machine operates on the principle of burning the combustibles contained in the atmosphere, and, in order to obtain a reading, a burning of the gas must take plaee. When high concentrations of the combustibles are present, there may be insuf ficient air to bum the gas, and an erroneous reading will be obtained. In such eases, the needle pointer will immediately be deflected full scale as the first traces of gas are drawn through the machine and are diluted by the air already present in the suction line of the machine. As the combustible gas con centration increases within the detector machine, the needle will quickly drop back to sero and remain there, giving the impres sion that no combustible gases are present. Consequently, close observance of the machine is necessary in the early stages of the test, to Insure against obtaining an erroneous reading. As a further safeguard, whenever the pointer indicates no combustible gases, the machine should be removed to fresh air and aspirated several times. .If there is a high concentration of combustibles present in the machine, a reading will be obtained on the machine as this dilution takes place. Exploslmeters are equipped with a leak valve which can be cracked to admit air when mixtures above the upper explosive limit are autpected. 114-7 EM004255 3. Oxvkct Testa Tests should be made st s sufficient maker of points within the ares or vessel to insure com plete coverage in the same Banner as described previously for the combustible gas test. Beckman analysers are used for conducting oxygen tests. C. Maintenance of Cas Testing Equipment The respective laboratory groups are charged with setting up mechanisms to insure the satisfactory operation of the detecting devices required far their use. The process operating group is responsible for the maintenance of any gas analysis devices which are assigned for their use. The laboratories, when called on, will assist in any way possible in the maintenance of these Instruments.

Costings on some welding rods can cause toxic fumes, such as Fluorides, Nitrogen Oxides, etc., to be evolved when welding. In most cases, supplied-alr masks (Scott Air-Pah) will be necessary for workers inside the vessel during burn ing and welding in addition to, or in place of, venti lation. Since gas tests for flamable or toxic materials will not reveal these special hazards, the gas tester and the process supervisor or operator should advise mechanical workers of the existence and toxic effects of any of the following: Metals Plastics Arsenic Brass Cadmium Copper Galvanized (Zinc) Lead (including lead primer psints) Mercury Monel Stainless Steels Vanadium Zinc Epoxy Resin Coatings or Paines Phenolic Resins or Coatings Teflon, Kel-F Polymers Rubber August 13, 1963 11A-11 E MO 04 259 Baton Route.

Monflame-type hot work includes use of power cools, grinding, chipping, drilling, power wire brushing, sandblasting, concrete cutting, soldering with soldering iron, using normally nonarcing electronic instruments, internal com bustion engine-powered equipment. B. Life of Permit 1. Hot work permits are good for one process shift. By endorsing the permit it can be extended an other process shift. Permits expire and must net be extended past 6:00 a.m., except that permits issued at the end of MC" shift within two hours of beginning work at 7:00 a.m. are valid until the end of **V` shift unless otherwise voided. 2. Permits are void if the work is stopped for safety reasons and the permit must be endorsed by the issuing party before work is resumed. C. Procedures for Issuing 1. The hot work permit is Mde in triplicate. The person doing the work gets the original, the gas tester gets the last (yellow) copy and the white copy rcMins in the book. When a gas test is not required, the yellow copy can be destroyed. 2. Every section of s permit form is provided for a purpose. Each section should be carefully completed. 3. Generally employee* receiving a work permit know little of proeeaa operations involved in the work to be done. These employees should be told about proeeaa factors involved in the job. Special precautions should be checked and written 115-3 E MO 04262 out .on tb permit. The employee receiving the permit should be Instructed verbally to Insure complete understanding. If the employee who issues the permit wishes the employee who does the work to check with him prior to starting the work, he should cheek the square provided for this purpose on the peralt fora. 4. Since fires may result from hot work, fire extinguishers and/or hose with pressure to the nozzle shall be in ready standby before issuing hot work permits. 5. The area where the work is to be done must be clean initially and kept clean as the work pro gresses.

In the case of very letge vessels such as bubble towers which have assholes or handholes located at vary does inter vals, it way be necessary to remove only part of the cover plates to insure e satisfactory test. c) In vessels that have been gas-freed by stensing, or are above atmospheric temperature for any other reason, a sufficient cooling period shall have elapsed before the gas test is made so chat the vapor temperatures approach that of the atmosphere. This requirement should prevail wherever gas tests are Bade of any hoe heavy oil vapors. Such vapors have a tendency to condense in the tubing of the conbustlble gas detector and give an erroneously low reading. Platting should include sufficient time for the equipment to cool before the gas tester arrives. A portable conbustlble gas alern,avaltable at the laboratories, nay be used in the vessel to overcome delays in letting the equipment cool. d) the 1068 threshold value fcr gasoline vapor with res piratory protection is 500 parts per Billion (American Conference of Goverseutel Industrial Hy gienists) .

Equipment and- machinery in the Plant are equipped with safety devices. There are many types of personal protective equipment available to you. Safety discussions are held frequently to acquaint you with safe work methods and to stress the importance of safety. Safety topics are included in such publications as the daily News Bulletin and Esso News. The Company wants you to be safety conscious; however, any program of this type requires certain rules and standards of personal conduct. Since the unsafe act of one per* son may endanger not only himself but others, the Company must establish safety rules and en force them.

Use this safety standard as a source of information and as a guide wherever it is applicable. In some circumstances deviation from these practices may be safe and desirable in the judgment of tha supervisors or operators. DEFIWITIOHS 1. Hot work is an operation that.may produce enough heat to Ignite flammable gas-air mixtures or flammable materials. 2. Cold work is work that ordinarily does not create enough heat to ignite flamable gas-air mixtures. 3. A aas test is a test made to determine whether flammable or toxic gas is present or to determine the presence of oxygen. 4. Vessel means all eloeed containers such as tanks, dnm, towers, barrels, pipe lines, barges and tsnk cars; also enclosures such as furnaces, which are used to confine flammable gases or vapors; and pits, tranches and open top containers greater than 4' in depth. 5. Unit operator is any employee in charge of a process unit. SECTION I - COTIES AND KISPOHSIBILITIES A. Process supervisors and unit operators shall: 1. See that the equipment has been properly prepared. EM004249 2. Designate on the work pereit the exact area and piece of equipment to be worked on and to be gas tested. 3. Check off on the pexslt font the types of teats to be performed. 4. Accompany the gas tester to the location where the teats are to be made. 5. See that gat tests have been made so that a safe job will result. 6. Call for rechecks by the gas tester whenever it it Is felt that such action Is warranted. 7. Issue a permit only when a complete, satisfactory gas test has been made where required. Unit operators approve only nonflame hot work and cold work permits. B. Laboratory gas tester shall: 1. Furnish process supervision and unit operator accurate and comprehensive information regard ing the presence of flammable or toxic gas in the area which the process employee has desig nated. 2. Indicate the results of his tests on the work permit form with any additional comments he may have that would add to the safety of the job. 3. Insure that the entire area and immediate sur roundings have been representatively tested. 4. Request the process supervisor or unit operator to take the necessary steps so that a complete gas test is issued. 5. Note on the permit form "Limited Test" if the process supervisor or unit operator requests a limited teat on the equipment. 6. Note coodltiena in the eree and surroundings which might laad to the presence ef gea or . vapor. If such conditions exist, they should be dlecwssed with the process supervisor or unit operator and noted on the permit form. 114-2 E PO 04 250 SECTIOH IX - GAS TESTS - GENERAL A. Types of Gs Test* The gas uses required in the Plant can be classified in three general groups. 1. Combustible Cas Tests an conducted to determine the percentage of combustible gases or vapors present in an atmosphere. Some of the combus tible gases and vapors found in Baton Rouge Plant operations are included in Appendix I attached. 2. Testa for Toxic Cases. Some toxic gases that are likely to be present in Plant equipment, the permissible levels and methods of determining con centrations are included in Appendix II attached. 3. Oxvsen Testa are conducted to ascertain the volume percent of oxygen present in an atmosphere. In addition to Insuring enough oxygen for personnel, oxygen testa auy be used to determine if there is enough oxygen present to support combustion. B. Cas Test Requirements for Various Situations 1. Insuring Against the Presence of Oxygen In Equipment Being Returned to Service Purging with inert gas is usually mors difficult than by other methods. Inert gas is composed primarily of nitrogen and carbon dioxide but may contain traces of hydrogen, carbon monoxide, oxygen, and nitrogen oxides. Alternate preasureing and venting the vessel to atmospheric pres sure will reduce the oxygen content of the atmosphere within it. After purging with inert gas, a sufficient number of tests shall be made with an approved oxygen analyser to give com plete assurance that a mixture is not present in the vessel which contslns more than 51 oxygen. Where hydrogen sulfide or carbon monoxide may be present, the 0, content should be reduced to no more than 2* due to the wide explosive range of these gases. These tests for oxygen content before admitting hydrocarbons need be made only in the caae of equipment purged with inert gaa. 114-3 EM004251 SBCTIOM II - GnmtAL A. Authority to Issue Cold work permits arc authorized by process super visors, unit operators, or assistant operators. B. Requirement* 1. Cold work permits are required Cor all mechanical work in process areas where hot work permits are not required, except work on meters and instruments in control houses may be done with permission of the process supervisor or operator, 2, Cold work permits are not required for work in Mechanical shops, on roads, fences, or build ings outside operating areas. C. Single Permits 1. The work covered by a single permit shall be limited to that which can be adequately described and for which proper precautions can be specified. Unless safety conaiderations make it inadvisable, such work as pump checks, plug valve greasing and clean-up may be covered by a single permit. D. Life of Permits 1. Cold work permits are good for one process shift. By endorsing the permit it can be extended another process shift. Permits expire and must not be extended past 6:00 a.m., except that permits issued at the end of "C" shift within two hours of beginning work at 7:00 a.m. are valid until 3:30 p.m., unless otherwise voided. 2. Permits are void if the work is stopped for safety reasons and the permit must be endorsed by issuing party before work is continued. E. Procedure for Issuing 1. The permit is made in triplicate. The mechanic gets the original, the gas tester gets a copy and a copy remains in the book. 116-3 EM004269 When a (as Case la not required, one copy can be destroyed. 2. Every section of a petalt foza is provided for a purpose. Each section should be cDepleted. 3. Generally employees receiving work petalts know little of process operations Involved in the work to be done. If the employee who issues the pcrale wishes the employee who docs the work to check with him prior to startlnf the work, he should check the square provided for this purpose on the permit fora. SECTION III - GAS TESTS AMD BLIKDINC A. Gas Test and Blankin( Requirements for Cold Work. Gas tests are required for the following activities: 1. Entry Into a Vessel With or Without the Performance of Cold Work a. All lines connected to the vessel shall be slipblinded with blinds of the proper rating or the lines shall be disconnected and blanked with blind flanges before the permit is issued. See Safety Department Sketch #39-134A and Engineering Drawing #0-1-1--41 attached. Quarter-inch thick slip blinds have an undrilled neck, series IS slip blinds heve one 3/8" bole drilled in the neck end series 30 slip blinds heve two 3/8" holes drilled in the neck. b. Combustible gas testa shall be made. It will normally be necessary to have the vessel completely freed of combustibles as indicated by a aero reading on the gas testing machine before permitting entry. In the cases where only ordinary petroleum hydrocarbons are handled, if for seme good reason it is not possible to eliminate completely the combustibles from the atmos phere, cold work may be permitted with concentrations up to 5Z of the lower explo sive limit. This is the maximum 116-4 EM004270 concentration for entry without airaupplled respiratory protection. Steps should be taken to insure that changing conditions do not result in an increased gas concentration. This My require that the gas tester stand by to test the atmos phere at frequent intervals. c. If there is a possibility of having inert gas present, tests for oxygen deficiency and carbon monoxide content shall be made. d. If there is a possibility that any other toxic Mterial is present, tests shall be Mde to insure that concentrations of such Mterlals are below the allowable maximum. Toxic Mterlals for which tests are required arc listed In Safety Standard Ho. 114. Test for hydrogen sulfide shall be Mde every time combustible gas tests are Mde. 2. Cold Work in Open Areas Where, in the opinion of the unit operator or the process supervisor, there My be excessive concentrations of combustible or toxic gases in some open area where cold work is to be performed, gas tests shall be Mde to insure the safety of the work. The requirements in this case are the same as for "Entry Into a Vessel", as outlined in Par. A. 1. above. The process supervisor or unit operator My issue a cold work permit without a gas test if, in his opinion, the area is suitable for the work. 3. Cold Work Requiring Contact With Flammable Liquids In some jobs, particularly cleaning work, it is necessary for the work to be performed near flammible liquids. In such cases the provisions applying to cold work in an enclosure or in an open atmosphere, as the case My be, shall be followed with regard to the general atmosphere. Necessary steps are to be taken to ukc 116-5 ENO 04271 certain that Ignition of the fl vapors does not occur.

Louisiana Safety Standard No. 117 Safety la Operation of Industrial Furnaces REVISION I I. SCOPE This safety standard outlines the recommended operation of industrial furnaces. It is Intended to be a general statement of good practices that apply under normal circumstances. Use it as a source of Infones* tlon and as a guide whenever it is applicable. Where it is necessary* the foreman or supervisors involved may change these practices. II. GENERAL INFORMATION It is important that everyone concerned with the operation of furnaces in the plant be acquainted with safe operating procedures. Furnaces burn an air-fuel mixture which* if not satisfactorily controlled* could result in explosions with resultant serious Injury to personnel and destruction of facilities. A torch of the asbestos wick type for use with equal parts of fuel oil and gas oil is generally used for lighting burners. Burners can be safely lighted by use of the pilots. The improved pilots nay be lighted from a small torch applied at the air-gas mixing head located outside of the firebox. The pilots and burners normally have separate fuel sources. III. SPECIPIC RULES A. Lighting Burners in Cold Firebox 1. See that the fuel main block valve is dosed. 2. See that the individual fuel block valves at the burners are closed. 3. Be sure all (blanks or slip blinds) have been removed from the fuel lines. 4. Make sure the fuel gas pressure is satisfactory. 5. Drain all liquid from the fuel gas manifold which serves the Individual burners* as well as from the fuel gas separator. 6. Open all air registers and dampers before ventilating firebox. 14004275 7. Open itua vide into firebox for at least IS Minutes. Operate draft fan. vhere provided, for 15 minutes in lieu of steam. 8. After blinds are removed, the fuel main lateral block valve may be opened.' After steaming the box, the bypass block valve at the automatic fireman control valve may be opened for starting up the furnace manually. 9. Adjust air registers or air intakes to burners to proper setting for lighting burners. 10. It is important that a check be made to assure that a draft (negative pressure) exists in firebox before attempting to light any burners. 11. Procure a torch lighter from the torch holder, light it and insert into furnace at burner, stand to one side, open the burner fuel block valve and ignite the fuel, then adjust the air to give desired flame adjustment. In event pilots are used, each pilot should be'ignited with the torch. Each burner should then be lighted from its pilot. Stand to one side as the fuel valve is opened. Light all burners similarly. Never attempt to light a burner from a hot vail or from an adjacent burner. 12. If the first burner that is attempted to be lighted falls to catch after a reasonable time, withdraw the torch or shut off pilot and again ventilate the firebox following procedure out lined in preceding directions. 13. If one or more burners go out but others remain lit, immediately shut off the fuel gas to all those that are out. Relight the burners progressively, using torch or pilots. 14. If all of the burners in a firebox or in one section of a firebox go out, immediately stop the total flow of gas to that section by closing the block valve in the fuel gas lateral. Close the individual burner valves. Steam out the furnace or operate the draft fan for a period of 15 minutes. Again relight furnace progressively in accordance with pro cedure outlined in preceding directions. 15. The burner manifold pressure should be maintained above 5 psig after a furnace is in normal operation. Zt may be necessary on certain occasion# to cut off one or more burners to msintain satisfactory pressure and insure that no burner will "pop" out. 117-2 EM004276 16 . When temperatures com within range of control, the auto matic fireman may be placed in operation by partially closing the bypass valve. The bypass valve is not shut off completely unless a second bypass is provided for keeping the burners lighted should the control valve jam shut, or unless approved pilots are used. If a low pressure fuel gas cutoff is Installed on the fuel gas controller, the bypass valve around the fuel gas controller must be closed after the burners are lighted. 17. To shut down furnace, reduce progressively the fires in intensity by adjustments of fuel gas control valve or lateral block valve. When the intensity of the fires has reached a sufficiently low point, the fuel gas supply may be completely stopped by successively closing the burner block valves. Before closing the last burner valve, close the lateral block valve and allow the pressure entrapped in the lateral line to be expended by burning the gas at the last burner. Close the last burner valve after which blanks can be installed in the lateral line as necessary. IV. OPERATING PROCEDURES FOR STEAM ATOMIZED LIQUID FUEL BURKEES Follow-che same general procedure as outlined for gas fired furnaces, with the following modifications. Prior to permitting the fuel to enter the burners, be sure that all condensate is drained from the atmomized steam system, then open and adjust steam into Che burner. Open the fuel oil lateral valve and light the burners successively. In shutting down burners, close oil valve first and allow the steam to blow the burner clear of any remain ing oil. The precautions of steaming the furnaces and the other funda mental safety procedures with oil burners are identical with those for gas fired furnaces. Except for the above modifications, follow che steps outlined in che previous section for gas fired furnaces.

Bia-(Hydroxyethyl) Cocoamine Oxide (EHJ 3732) It is intended to be a general statement of good practices that apply under normal circumstances. Use it as a source of informa tion and as a guide wherever it is applicable. When it is nec essary, the foreman or supervisor involved may change these practices. II. General Information These additives are used in many areas of the Refinery. They have a severe irritation effect to the skin and eyes and are con sidered toxic. They say cause acute systemic poisoning. These materials are received in 55-gallon drums or in tank cars. They are normally stored in a central location from which small amounts are withdrawn for general use in the Refinery. Wherever these materials are stored or used there is the possibility of skin contact. Wear proper protective equipment when handling these materials. III. Specific Precautions in the Handling of Aaine-Tvoe Additives and TBC A. Use hand pump or similar equipment to avoid splashing when transferring these materials from a storage drum to a portable container. Use an approved type of safety can as a portable container to prevent leakage and splashing while in transit. EM004278 B. Hur a face shield, protective gloves, and protsetive ault when connecting or disconnecting llaca co task cars or storage vessels containing or having contained amine-type additives. Wear face shield and protective gloves vhea drawing sample* free 55-gallon storage drums. C. Hear rubber footwear when walking in an area Chat nay have been contaminated as a result of an additive spill or when the specific Job is such that an additive spill may occur. D. Clean up leaks or spills of additives immediately. E. Work clothing contaminated with these materials should be changed and laundered. F. Additives should be removed from the ekln with soap and watar. Report to the Medical Department if additives get on the skin. C. If chemical should get In eyes, flush with water-for 15 minutes and report to the Medical Department. B. Properly label additive storage drums and portable con tainers. I. Kever permit empty additive storage drums to remain In process area. Have them transported to the burning pit area for reconditioning ox disposal. J. Avoid excessive breathing of vapors.

SCOPE Tbia safety standard covers the basic practices to be followed for the safe operation of fork life trucks. In sane circumstance* deviation from these practices ay be safe and desirable if the Judgaent of the fore men or supervisors so indicates. XI. GENERAL Safe equipment and safe working conditions alone will not prevent all accidents. Safe operators are also needed. Only a safe operator can perfort his Job effi ciently and properly. A lift truck can be compared to an automobile. The causes of most lift truck accidents are usually the sane as the causes of traffic accidents--unsafe acts and violations of rule*--thing# that the driver can control. The following safe practices are based on an examina tion of the causes of lift truck accidents and their remedies. III. BEFORE STARTING WORK 1. Cheek your brakes, steering apparatus, horn, lift echanisa, controls, guards, and tires. 2. On gasoline trucks, make sure you have plenty of gasoline and oil. 3. Report any defects immediately to your supervisor. IV. USE OF TRUCK 1. Never operate a defactive truck. If trouble develops on the job, stop and consult your supervisor. 2. Never allow any unauthorized person to operate your truck. EMO 04280 3. Never permit anyone to ride on any pert of pour truck, exception: Supervlaore asp authorise two person* to ride when one is undergoing training. 4. Never overload pour truck* To do so nap damage the hoisting mechanism or result in an accident. 5. Never use pour truck as a battering ran. 6. Never tov rail freight cars with pour truck. They map get amp and drag the truck. 7. Pushing a lift truck with another in order to get it started is prohibited. 8. Avoid using a gasoline-powered truck in small build ings without proper ventilation. Carbon monoxide poisoning map be result. V. PARKING 1. Never step out of pour truck until It has come to a stop. 2. When pou leave pour truck set the brakes. 3. Never leave pour unattended truck with motor running. 4. Park pour truck so it will not Interfere with passage of other vehicles or person*. Never park on* or within six feet of* railroad tracks. 5. If necessary to park on incline* sec the brakes and chock the drive wheels. 6. Park Indoors with forks under a flat pallet or bench to prevent tripping. Out of doors, put your forks on the ground. VI. DRIVING 1. Never drive with wet or greasy hands. 2. Obey all traffic regulations. 3. Avoid driving over objects lying on floors or roadway. Driving over acrap lumber* piping* or other such materials will cause damage to the truck and may shift or topple the load. 12S-2 EM004281 4. Always drive at a safe speed. Slow down when H"t turns. 5. Drive slowly over rough roads. Natch for uneven ' spots. This Is particularly Important whan making turns, or when operating trucks with a narrow width or short length la proportion to the height. 6. Approach blind corners slowly, keep to your right, and sound horn* 7. Natch for persons who may dart out In front of you and for other approaching vehicles. 8. Always give warning when you approach anyone from the rear. 9. Tour horn Is to be used only as a warning to others and not to demand the right-of-way. 10. Keep your feet and hands inside the truck exceptwhen signaling. 11. Give proper band signals for turning, slowing, or stopping. 12. When driving without load, keep forks A in. to 6 in. above floor or ground. 13. before crossing railroad tracks, make sure way Is clear. When crossing tracks, hold steering wheel firmly. Cross rails diagonally. 14. Stop, look, and sound horn when leaving buildings. 15. Approach floor openings, elevator wells and loading platforms slowly. 16. Before entering an elevator be sure that its capacity is sufficient for the weight of the truck plus the load. 17. When you enter an elevator, lock brakes.and turn off power of truck. 18. Keep away from the edges of platforms or ramps. 19. Test brakes before driving down ramps or slopes. Never allow pedestrians to walk ahead of you down reaps or slopes. 125-3 EM004282 20. Keep sufficient clearance between tb lift truck and other objects or material*. Mover cat cor ner* around stack* o material or ration*ry object*, such os machines or colwns. Uhon entering doorway*, freight cots, or elevators, sake sura you have proper clearance on both sides as well a* overhead. 21. Avoid turning around in crowded aisles. 22. When following another truck kaep a safe distance behind. Minims: IS feet Indoors; 30 feet outdoors. 23. Never travel abreast of another truck. Never race another truck. 24. Where possible, face in the direction of travel. 25. If necessary, back down rasps or inclines to avoid spilling the load. VII. STOPS AND STARTS 1. Avoid sudden stops and starts. These nay cause skidding or toppling the load. 2. Travel slowly on slippery surfaces. 3. Never use reverse as a brake. Stop vehicle with brakes before changing direction of travel. 4. Always look to see that the way it clear before starting ahead or backwards. 5. On three-wheel trucks, check position of trail , wheel before starting or truck nay swing unexpectedly. VIII. CASEOUS AREAS 1. Never operate your truck in gaseous area. 2. Keep alert for spills or other sinllsr conditions. IX. CARRYING A LOAD 1. Never load your truck beyond its rated capacity. 2. Always carry loads 4 to 6 in. above floor In ware house, and 6 to 8 in. in yard. Carrying loads close to floor reduces possibility of turning truck over or dunping load. 125-4 E PO 04283 3. Never carry a load so high that you cannot see ahead. If accessary, operate truck in reverse. 4. Avoid carrying loose material on forks. Use pallets wherever possible. 5. File material securely on the pallet at all times. Block round objects such as pipe or drums so that they cannot roll. 6* Place a red flag on material that projects on either side. 7. Carry the weight dose in on the forks. 8. Never allow anyone to stand under elevated loads. X. USE OF LIFTING DEVICE 1. Before lifting be sure that loads are stable and properly balanced. 2. Pick up the load under the center of its weight to avoid tipping the truck over or shifting the load. 3. tilt the load against the backrest before moving the truck. 4. Be sure to return tilt to vertical before lowering or piwkirg up load. 5. Run the forks as far as possible under losd to be lifted. Never pick up load until forks are properly placed beneath the pallet. 6. Lower your load slowly. A sudden stop will caus^ machine to tilt forward and may tip machine or throw operator. XI. STACKING AND REMOVING MATERIAL 1. Never overload floors when stacking material. 2. Be sure there is sufficient head room when raising loads. Watch for beams, pipe lines, lights and oeher obstructions. 3. Be sure stacked materials are not top heavy. Poorly piled materials are dangerous. 125-5 EM004284 4. When placing or when picking up pallets, be sura not to unbalance pile. 5. Hern other employees to stand clear when stack ing or removing material. 6. Avoid stacking material in roadways or aisles. Allow ample room for passageways. 7. Observe clearance rules at aisles, sprinkler heads, railroad tracks and the like. 8. Never obstruct fire fighting equipment. 9. Keep fire doors clear. 10. NEVER attempt to reach through uprights. To do so may result In serious injury. XII. LOADING AND UNLOADING CARS AND TRUCKS 1. Before entering freight cars, highway trucks or trailers, be sure their brakes are set* Use chocks If needed to prevent movement. 2. Before entering freight cars, trucks or trailers at loading platforms, be sure the loading plater, are secured. 3. Never use dock boards or loading plates that are damaged. 4. Before driving into freight car, walk In car and Inspect floor. 5. Always have both doors open before operating gasoline lift trucks inside box cars. 6. Enter and leave freight cars and trucks slowly. XIII. CONDITION OF SURFACES AND PALLETS 1. Maintain floors, ramps, road surfaces and the like in good condition and free of debris at all times. Report any bad spots imediately to your super visor. 125-6 EH004285 2. Report slippery conditions around warehouses, reaps and platforms promptly. 3. Never use defective pallets. XIV. REFUELING ENGINE-DRIVEN TRDCXS 1. Never refuel a lift truck inside a building. 2. Make sure hose nozzle makes contact with tank while filling* this will prevent static sparks. 3. Shut off engine and set brakes before refueling. 4. Avoid overfilling the fuel tank. In the event of a spill, wipe up before starting motor* 3. Store and carry gasoline in safety cans where pump is not used* XV. SPECIAL PRECAUTIONS FOR ELECTRIC-DRIVEN TRUCKS 1. Never use reverse controls for brakes. 2. Never operate with weak batteries. 3. Cut off power and set brakes before starting to change battery. Make sure master switch on charging circuit is off before plugging in for charging or unplugging after charging. 4. Keep open flames away from battery. Hydrogen gas may be present which may cause an explosion or fire. 5. Keep all live parts protected. 6. When lifting batteries with chain slings or metal grips, avoid short circuits by preventing metal parts from touching the contact terminals. XVI. PROPER DRESS FOR HANDLING MATERIALS 1. Wear gloves and goggles when handling dangerous materials. 2. The wearing of safety shoes is recommended. 3. Wear a safety hat while operating a fork lift truck. 125-7 EM004286 4.

Louisiana Safety Standard No. 129 Chlorine Revision II I* Scope Thia safety standard covers the basic points in the protection of personnel fro* the hamful effects of chlorine. It is Intended to be a central statement of good practices that apply under somal circus* stances. Use It as a source of information and as a guide wherever It la applicable. In some circum stances, deviation from these practices may be eefc end desirable if the judgment of the foremen or supervieors involved so indicates. II. General Information Chlorine is a toxle material. It is recognised by its pungent odor end greenish color. Liquid chlorine causes blisters and damage to the akin. In liquid or gaseous states it can cause damage to the eyes and respiratory system. At concentra tions of 1,000 parts par million it la fatal. It mixes readily with other chemicals. Violent ex plosions have occurred where chlorine was reacted with hydrocarbons, particularly when the chlorine la in the liquid state. Any process where chlorine la reacted with hydrocarbon* cocuId be carefully studied prior to the operation and accurately controlled during the operation. Chlorine la normally stored in the plant in one ton, high-pressure cylinders. It la used from these cylinders primarily in cooling tower water, in making sodium hypochlorite, and in. experimental projects. In the Chemical Plant area it la used in making ehlorobutyl rubber. Chlorine for this purpose la stored in a tank car and small tank next to the substation west of Ho. 2 Steam Cracking Unit. In the Petroleum Operations area chlorine is used in making sodium hypochlorite at the Light Oils Finishing Plant. EM004290 Chlorine Is taken directly fro* the task ear through the aodlua hypochlorite blending systea. III. Specific Precaution* A. Hear rubber protective clothing when there la a possibility of exposure to high concen trations of pure chlorine. B. Avoid breathing chlorine gas. When Investi gating leaks, wear a self-contained, supplledalr sank. C. Never try to locate a chlorine leak by swell ing. Use a rag soaked with strong saonia water and held on the end of a stick or rod. As the rag Is passed along the piping or velves to be tested, a white vepor (awonlua chloride) will Indicate a leak. D. Never allow Moisture to enter chlorine pip ing while It is disconnected from the cylinder or car. This will rapidly corrode the pipe. E. One ton and 150-lb. chlorine cylinder and tank car emergency repair kits are available through the 7510 Mechanical Shift Foresen. They are stored near the 7510 office area, northwest corner of the Central Mechanical Building. Call telephone 7510 or 7486 (Mechanical Shift Foreman). In the event of Major trouble. It aay be desirable to call Solvay Co., telephone EL 5-6661 (8:00 s.m. 4:30 p.., Monday through Friday) or EL 5-8024 (after 4:30 p.a. and on Saturdays, Sundays and holidays). F. If chlorine is detected in the air, either by sight or saell, rewcaber the following points: Get out of the area. Keep head high; chlorine seeks low est level. . Refrain fro coughing if possible. Avoid deep breaching. Keep south closed. G. Observe the following precautions with chlo rine tank cars, cylinders, and lines: 129-2 EM004291 1. Never drop chlorine cylinders or permit then co strike each other violently, tswovs valve caps only when the cylinder or car la beInc prepared for use. 2. Keep valves closed when cylinder or car Is not in use* even when empty. (Moisture suit not be allowed to eater cylinder or car*) 3. Opes valves slowly, using only handles provided. 4. Use only connections nade specifically for chlorine valves. The outlte of these valves is not a standard pipe thread. 5. Cylinders or cars are not to be altered in any way. No repair is to be nade on cylinders, cars, or valves except in case of an emergency. Call 7510 when emer gency repairs are necessary. 6. Never try to renove any of the fusible plugs in the ends of the cylinders. 7. Store one-ton chlorine cylinders hori zontally. Never subject cylinders to heat since the fusible plug nelts at about 160 F. 8. Only one cylinder of chlorine should be delivered to a location at one tine, except where high chlorine consumption would sake this impractical. The prac tice of having a spare cylinder on hand at a location only Increases the exposure to a larger quantity of chlorine should trouble arise. 9. External pressure regulators, installed in chlorine lines, should be ss near the cylinder or car as possible to minimise condensation. In the presence of moisture, both gaseous and liquid chlorine are ex tremely corrosive to metals. 10. Keep chlorine lines at minimum pipe size (1/2** will probably suffice) and length. 129-3 ENO 04292 11 . la cam of fir* la an uu adjaeeat to a chlorine cylinder or can, vater iron a nonltor or spray nossle should he sprayed on tbe container to prevent possible pressure build-up due to host* Excessive heat nay cause the fusible plus to rupture and release chlorine to tbe atmosphere, thus creating s problsa of fighting s fire la e toxic atmosphere. 12. If the "shock treetnent" cycle of vater treating la to be used, chlorine should be shut off at tbe cylinder or car after each periodic or intermittent treating. Never block tbe chlorine flow at tbe chlorlnator. Ky blocking et the cylin der or car, the residue chlorine In the line will bleed off to the cooling tower reter then reaain trapped in the line.

SCOPE Thla aafcty standard covers the basic points in the protect tlon of personnel from the harmful effects of hydrogen sulfide. It is intended to be a general statement of good practices that apply under normal circumstances. Use it as a source of information and as a guide wherever It la applicable. In some circumstances, deviation from these practices may be safe and desirable if the judgment of the supervisors involved so indicates. 11, GENERAL INFORMATION Over the years in the oil and other industries, many employees have been severely injured and some killed by highly toxic hydrogen sulfide gas, commonly known as "HjS". In many cases, these were older, more experienced employees who became complacent about this deadly gas. And, in many cases, the injured did not realise how toxic this gas really is. Important Physical and Chemical Properties Hydrogen sulfide is s colorless gas with an offensive "rotten egg" odor. The gas is slightly heavier than air. It ia a flammable gas having a flamable range of 4.3 to A6X by volume In air. The auto ignition temperature ia SOOT. Toxlcitv The most important consideration about hydrogen sulfide is its toxicity because it Is so deadly. The chart Included is graduated from OX by volume in air to 1/10 of IX by volume in air. In order to more clearly outline the toxic profile, we have placed the corresponding parts per million along the scale. At ten parti per million in air it will be noted the gas can be distinctly smelled due to its offensive "rotten egg" odor. EM004294 Twenty parti par million li the recognized threshold limit value or tba concentration la which a parson can stay sight hours without Injury. Stop for a minute to consider the small amount which a parson can breathe for eight hours, twenty parts per million, as contrasted with the least amount that will bum and explode in air, >3000 parts par million. As we go up the scale, 100 parts per million will deaden the sense of smell in 3 to IS minutes. This can causa the victim to be lulled into the feeling that there is no longer any gas where be nay be working when in reality the concen tration has mot changed. At 300 parts per million, the sense of smell is deadened quickly. If the victim stays in 500 parts per million, be may lose sense of reasoning and balance* the effect on the nervous system is very pronounced. With this concentration, respiratory paralysis sets in quickly. Unless the victim is rescued, brought into fresh air and glvan Immediate arti ficial respiration, ha may die. It la extremely important that the man making the rescue wear the proper respiratory protective equipment. At 500 parts per million, unconsciousness will be rspldly produced. The Injured will continue to bresthe sc a diminishlngly lower rate until branching stops and Che victim will die unless rescued and given artificial respiration in fresh sir. At 1000 parts per million and above, Che victim will become unconscious at once and his breathing will shortly stop In any case, where the breathing stops for more than 4 minuses, permanent brain damage may occur. In Suamary: (a) The victim may have encountered 100 to 200 parts per million for short periods and gotten by. He may become over-confident of his ability to rescue hin self . (b) His sense of smell may be deadened very quickly. (c) The effect on his brain may cause him to stumble, fall and crawl, and Impair his ability to reason. He may not know where or how to escape. (d) A quick change in wind direction or concentration of the gas may trap the victim. He cannot hold his breath very long, particularly under stress, and with air unsafe to breathe, he Is in a bad way. Flammability Hydrogen sulfide is a flammable gas. In mixtures in air between 4.3 and 46Z by volume, it is explosive. This explosive range is one of the broadest of the chemicals. 139-2 E MO 04 295 As u oaplt, th explosive rest* of gasoline vapors la sir 1* fro 1 to 6X. Hbto hydrogen tolfllt bum, It (om sulfur dioxide and water. The auto ignition temperature or the surface temperature which will ignite a flaMsble mixture of hydrogen sulfide In air is 500*F. This figure is lower than most gases or vapors handled in the refinery. Precautions for handling or working in areas where there may he hydrogen sulfide gas: 1. Never stand on the side of eny opening or leak where escaping hydrogen sulfide will blow toward you. Always stand "up-wind". 2. Haver tty to determine the presence of hydrogen sul fide by sense of small. Tbs Industrial hygienist. Css Tasters in laboratories and Safety Department have hydrogen sulfide indicators. Call then if you are in doubt. 3. If a break in a line carrying hydrogen sulfide occurs, leave the tone of exposure and do not re-enter without a self-contained breathing apparatus (Scott Alr-Pak). A. When geuging or sampling ships, tanks, barges, com partments containing sour crudes or sour distillates, wear self-contained breathing apparatus (Scott AirFak). ' 5. Inspect cylinders containing hydrogen sulfide care fully for leaks at valves and connections. Never store cylinders in an enclosed ares unless there is adequate ventilation. 6. In the laboratory, handle hydrogen sulfide or hydrogen sulfide bearing materials under a hood. 7. When opening equipment which has coneslnsd hydrogen sulfide, self-contained braathint apparatus must be worn. 8. If an employee is overcome by hydrogen sulfide, wear self-contained breathing apparatus to rescue him since he is, in all probability, in e sufficient H2S concentration to knock you out. Take him to a fresh air area end if he has stopped breathing administer artificial resuscitation by eny method you know. Have someone else suamon the ambulance. 9. Caustic sods which has been used to strip H2S from a stream will liberate its H2S if it encounters an 139-3 EM004 296 acidic atreaa.

Louisiana Safety Standard No. 143 Bot Work on RafJ-ery Equipment in Saxvice Containing Hydrocarbons or Other Fla--abla Hatarlala (Bot Tap Procedure) X. SCOPE This safety standard outlines the minings safety pre cautions for hot tapping, installation of electrical connections or cathodic protection devices and other hot writ on equipment in service containing hydrocar bons or other flammable materials. It is intended to be a general statement of good practices that apply under normal circumstances. Use it as a source of information and as a guide vberever it is applicable. Where it is necessary, the foreman or supervisors involved may change these practices. II. GEXERAL IMTORHATION Hot writ on equipment in service containing hydro carbons is safe if proper precautions are taken. Each job should be considered on an individual basis and be properly justified before authorisation is given. Can cel hot work permit when specific hot vork job is finished. The Process Section Supervisor In charge of the equipment involved authorisea each job. Where hot work is done on a pipeline passing through one super visors* area but the operation is controlled by another, both wit* he required to approve. III. APPROVALS To maintain control of the conditions under which hot tapping can be done r :nponsible Process Section Super visor will: A. Determine that the contents of the system will permit hot tapping. Hot taps on lines or vessels containing corrosive or toxic materials, such as EM004299 hydrogen sulfide, caustic soda, stxlfuric acid, aemonia, ate., should ba (Ivan special con*Idara tion. Certain materials may causa metallurgical changes In the beat tone. Carbon steal. Cor example. Is changed metallurglcally sc elevated temperatures in the presence of caustic or ele mental sulfur. Hot tapping machines, depending on their design, are limited to use up to their maximue pressure-temperature conditions. Some steels and some thicknesses of metal require stress relieving. Hot tapping should never be done where equipment Is operated over its rated working'pressure and temperature, nor on equipment operating at less then atmospheric pressure. Welding should not be done where Internal pressure exceeds 3S0 pfig. The Inspection Section of the Mechanical Engineer ing Department should always be consulted to make sure all the above factors have been considered. Hot tapping equipment containing an air-vapor mixture or compressed air lines or equipment should be done only after thorough investigation end approval by the Safety Department end the Inspection Section of the Mechanical Engineering Department. Heating compressed air lines may causa detonation if lubricating oil has been vaporised end dis tributed through the system by the compressor. B. ' A hot work permit must be issued. State condi tions under which hot tapping may be done. A gas test of the hot work sres may be required. An inspection of the parent metal is necessary. C. Avoid hot tapping adjacent to flanged or threaded connections since the welding may cause them to open and leek. D. Observe the operation to make sure these condi tions set forth are being followed during the job. IV. PROCEDURE TOR HOT TAPPIHC A. Make sure the correct equipment or line hat been selected to be hot tapped. 143-2 EM004300 B. The necessary approvals should be obtained. Con sult with Mechanical supervision end always obtain approval of the Inspection Section of the Mechani cal EngineerIns Department when asking hot taps. In certain instances you aay wish to consult with the Safety and Fire Departments. C. A hot work permit should be issued. Provide at least one 30*lb. cheaical extinguisher and a 1-1/2" fire hose connected and with water at nozzle. D. Xt should be determined by the Inspection Section of the Mechanical Engineering Departaent by use of hnmsar testing, ultrasonic thickness devices, kadiography, or by the use of other approved thickness aeasurlng devices that the equipment to be hot tapped is of sufficient strength and thickness to receive the connection. Previous inspection records and data on corrosion rates will be found helpful in asking this determination. E. Studies have indicated that steels should be pre heated before welding when the fluid or aetsl tem perature is under S0F. Special treatment is required for high tensile alloy steels and special welding rods must be used. F. Select the proper fitting to be used In asking tha connection. Thare are many types of connecting fittings available, such as Weldolets, saddles, nozzles, and plain nitres. Design connection end reinforcing pad, if necessary, according to proper code, i.e.: ASME Pressure Vessel Code, API 650 Specification for Welded Storage Tanks, or ASA B 31.3 Code for Pressure Piping. Be sure the fitting is of proper length to accommodate the high tap machine. G. The aaviana temperature of the Hillco hot tap machine is limited by the packing to 700F. The pressuretemperature rating of this machine is equal to the rating of a 300-pound flange. If an adapter spool is used, 300-pound to 150-pound, the lower, flange rating of the adapter is the limiting factor. If the temperature or pressure sbove those specified is desired, the Inspection Section of the Mechanical Engineering Department will develop particular appli cation with the supplier of the machine. The machine, its cutter and pilot drill should be care fully inspected before a hot tap Is made to be sure it Is in satisfactory condition for use. 1*3-3 EKO 04301 H. the fitting should b welded to the equipment to be hot topped. Avoid the uae of large size welding rods to prevent burning through lines while welding. The fitting atist be properly positioned to prevent mieellgnmcnt of the tapping machine when the cut is made., The machine Is usually set at right angles. I. A full opening gate valve is next attached to the branch noszle. It may be necessary to grind the seat ring lugs off to permit the cutter to pass through. J. The finished welding should be tested.before cutting Is started. If testing is determined impractical, the Inspection Section of the Mechanical Engineering Department should be advised before welding in order that welding methods may be followed closely. If che line or vessel is above 20GF, an air tast soaping the welds for leaks may be used. K. Install cutting machine on gate valve. The small vent connection on the machine should be open. Extend boring bar through opening several times to be sure the cutter does not jam or drag. L. Adjust boring bar atops and drill entry point. When pilot drill penetrates equipment, close vent valve on cutting machine. In addition to the machine stop setting, it can be determined when the cut is finished by speeding up of the air motor. Running the machine a few turns will remove burrs. M. Retract boring machine, close valve, and open bleeder. In event the blank or coupon is lost, no attempt should be made to "fish" for it. The equipment may have to be shut down to recover it. N. The cutting machine is removed and the connection is ready for use. SPECIAL CONSIDERATIONS A. Pipelines 1. In doing hoc work jobs of this type below grade level, provide an excavation to permit 143-4 EM004302 quick access sad exit by ptnoontl. If tbs excavation is greater then four feet la depth, e s*s test should be made. Use an sir siphon or some other positive means to ventilate the axeavatlon. If the job la above ground in e congested area, take the necessary precautions to prevent trapping personnel. 2. Flow should be malatalaad until after welding operations have been coexisted. If the line Is long and heat can be dissipated without flow, it nay be discontinued, the line should fas kept filled but cere muse be taken that liquid expan sion is relieved. A line containing s flammable mixture (1 to 6Z hydrocarbon in 94 to 99Z air) should never be heated. 3. Definite erring--ante should be made for prompt cn--unlcatlon with those at the job site to give notice of changed conditions within the line, such as interrupting flow. 4. In certain esses such as flare lines or others where there nay be insufficient or no flow, it is necessary to flush the line with staaa, inart I. or hydrocarbon gas and keep It flowing during the welding operation. 5. Where a line is underground and mis' through a casing, be sure that the line and not the casing is being hot tapped. Tanks 1. All Tanks - Never punp in or out of, or agitate the contents of, tanks involved in hot work. If the vapor space is above 30Z of lower explo sive limit or within explosive range, do not do hot work. The egltator switches should be tagged open. Close and tag "DO NOT OPEN" all valves at the tanka except: a. The gas blanketing velvet. b. The beater coil valves where vapor space tests above explosive range. (Blank steam 143-5 EM004303 inlet nlw If v*por space is loss than SOX of lower explosive limit.) 2. Cob* Roof Tirti - Maintain tt lsat three face of liquid head above the hot work arcs when welding or burning or similar hoc work is being done. Hake a tape gaug*. 3. floatlna loof Tanks - Make hot tap at any point below tba wind girder on the outside of the tank shall providing it Is 3 fact below the liquid level, lever do welding or burning or similar hot work on the roof, on the sleeves of the roof lags and pontoon hatches.

Scope This safety standard outlines the mlnlmtm safety pre cautions for use of seal pints In hot work Jobs. It is Intended to he a funeral statement of food practices that apply under normal circiastanccs. Dse It as a source of Infomatlon and as a guide wherever applicable. Except In emergencies, deviations nay be node In these practices only after the supervisor who writes the permit has consulted with his supervisor about the deviations. II. General Information Hot work on piping out of service containing hydro carbons Is safe if proper precautions are taken. Where seal plugs arc used each Job should be con sidered on an Individual basis and be properly justified before authorisation Is given. The Section Supervisor In charge of the equipment Involved authorises each Job. Where hot work Is done on s pipeline pasting through one supervisor's area, but the operation is controlled by another, both will be required to approve. In some cases the Section Supervisor may wish to review the work to be done with the Mechanical Division supervisors and repre sentatives of the Safety, Mechanical Engineering, and Fire Departments. III. Specific Procedure for hot work on pipelines where seal plugs are to be used: A. The origin and destination of the line and connecting laterals should be determined and all operators involved should be notified of the work being done so that the line will not be used until sll work is completed. B. 1amove sll pressure from the line to be worked. EM004 311 C. BLank the 11m to bo worked and *11 coonectlot lines at the point nearest tb* verb. D. A hot work pexnlt must be issued and at least one 30-pound ch--lctl extinguisher end a 1-1/2" fir* boa* contacted and with water pressure at tb* noaala should ba at the scene of the work. . In cases where a line is cold-cut or opened and a blind flange cannot ba used to close tb* ends, a plug eust be placed in the open ends of the line. The plug is so designed that it foxes a vapor-tight seal in the line. It is not desianed for use eraInst pressure. An adequate slsad vent eust b* provided to vent any gases end prevent pressure on the plug. This vent eust be far enough away free the hot work so that gases released will not be ignited by tb* hot work. Checks should be end* to make sura that the vent bleeder connection In the seal plug, as wall as the vent hose, is free free any obstruction. Venting should ba don* by the following eatbods. 1. The seal plus is to be used only to affect a vspor-tlaht seal. The seal plue eust not be used to withstand pressure. 2. The seel plug is designed with a vent at its center point. The seal plug vent eust ba used. The vent la extended by pipe or hose a ainlnua distance of 25 feat free the hot work. The end of the pipe or hose eust be inserted in a bucket of water so that gas released eay be positively detected by bubbles in the bucket of water. Periodic checks should be Bade of the bucket of water to detenln* if any bubbling is taking place. A release of gas causing an unusual eaount of bubbling is an indication to discontinue hot work and investigate. Additional venting will be required to reduce the pressure in such cases. 3. In order to provide adequate vent to prevent pressure on the plug it Bay be necessary to provide vents in addition to 2 above. These should be adequately sized drains, blaeders, spread flanges or other openings far enough fro* the point of hot work to present no hazard. Tb* vents shell be located so that traps, bends, and loops in the line do not nullify the ability of the vent to prevent pressure on the plug because of liquid head. 146-2 EMO 04312 f. Revet do hot work, locate ground eneeactlona for tbo veldlot --chlnot, or operate internal com bustion engine driven equipment near the rent or opening, Ground connections should be mode on the w line or vessel ee thee upon which welding la done. C. Never do hot work on the line until the plug is installed, Neke a gas test of the hot work area end in the 12-lncb opening between the end of the pipeline and the eeel plug, B. In congested area containing other lines or equip* went, existing pipeline IdeatIficetloo mspa end/or piping Index should be readily available for use la case of an emergency. 1, Avoid standing or working in line with a aaal plug. They have been known to blow out.

Where it 1* necessary, the foreman or supervisor* Involved nay change these practice*. II. CCTEIAL IKTORHATION Hot work on equipment in service containing hydrocarbons is safe if proper precautions are taken. Each job should be considered on an Individual basis and be properly justified before authorisation is given. The section supervisor in charge of the equipment involved authorises each job. Where hot work is done on e pipeline passing through one foreman's ares but tha operation is controlled by another, both will be required to approve. III. APPROVALS To maintain control of the conditions under which welding on Weld+nd couplings in service can be done, responsible Process Supervisor will: A. Determine that the contents of the system will permit Weld+nds welding. Special technical consideration should be given when welding on alloy Unas, oa lines containing corrosive or toxic materials (such as hydrogen sulfide, caustic, acid, umoaii, etc.) and on lines containing hydrogen, air-vapor mixtures or compressed air. EM004314 Manufacturers1 instructions era furnished with each new coupling; however, the --allowable pmittm prior to voiding as shown (70Z to tOX of actual tost pcoaauroa for coupling slippage) ato considered ex cessive for normal usage. Modified allowable pressures that nay be applied before welding* baaed on plant testa, are included in the table (Appendix X). To avoid a blowout of the line during welding, the line pressure should not exceed ISO pal for extra strong 2" piping and standard weight larger site piping (Appen dix X) without careful review of the dretastanees by process and inspection personnel. Whan welding is approved for pressures above 350 pal, use small site electrodes to avoid excessive beating of the pipe seal. After welding, pressures attainable with the couplings approach the mavleia for the coMonly used piping (Appendix I). Welding on Weld+End equipment should never be done on equipment above its rated working pressure end temperature, nor on equipment operating at less than atmospheric pressure. The Chemicals Technical Department or the Mechanical Engineering Department should always ba consulted to make sure ell the above factors have been considered. Weld+nd* welding on equipment containing an airvapor mixture or compressed sir lines or equipment should be done only after thorough investigation and approval by the Safety Department, the Chemicals Technical Department or Mechanical Engineering Department, and the process department concerned. Heating coapressed air lines may cause detonation if lubricating oil has been vaporised and distribu ted through the system by the compressor. B. A hot work permit must be issued. State conditions under which Weld4nds welding may be done. A gee test of the hot work srss may be required. An inspection of the parent metal is necessary. C. Observe the operation to make sure these conditions set forth are being followed during the Job. IV. PROCEDURE FOR WELDING ON VELPtEHDS IN SERVICE A. When seal welding Vld+Eod, general hot work pro cedures should be followed with equipment containing hydrocarbons. The Chemicals Technical Departeent or 147-2 EM004315 Mechanical Engineering Department should be notified before the line has been cut. B. An Inspector con determine that pipe well thick* nesses ere satisfactory for welding the couplinx before cutting or welding. C. Prior to welding. Weld+End couplings should be equipped with gasket seels suitable for temperature during welding end process operations. Temperature limits of available seels are as follows: Standard Neoprene Seal Silicone Seal Asbestos Klca Seal 2S0*F SOO*F 1000'F Although the standard Keopreoe seal is satisfactory for fluid temperatures up to 250*F, the silicone seal should be used where a coupling is installed on a pipeline handling a gas that has a low flow rate. More welding heat is transmitted to the seal when a gas is in the line then when the line contains oil or other liquids. D. loth lines shall be cleaned to insure seating of gasket seals. (Beveled side of gasket toward center of coupling.) Leave approximately 1/4" space between pipe ends and slide coupling on pipe to center it over Joint. E. tbs side clamping screws, centering the coupling on the pipe. These screws resist end pull of the pipes snd center the coupling so that the gasket will sest properly end so that seal welding can be done properly. F. Tighten the end thrust screw* until snug. Then start going around from screw to screw, giving each screw a l/8th turn each time. Do this for eight to ten rounds. These screws push against a thrust ring which compresses a packing ring and provides a pressure-tight seal. C. Use of couplings on light-wall piping requires caution in tightening screws and welding. Clamping screws should not be excessively tightened since the ends of the piping may be pushed inward snd cause seal leakage. Tha coupling should be carefully centered over the pipe Joint. The allowable pressures during welding must be determined for each esse, and use of small slse welding electrodes is nscessary to avoid burning through the pipe wall. 147-3 EMO 04316 H. Contact Process Supervisor to start sad Mintain flow through line. After flov bee been initiated the welding should be eoepleted promptly. Otherwise, problems with seal leakage might occur or the piping might work loose. If not properly anchored, and pull from, the coupling. If it is Imperative to consider delaying the welding, each Installation should be reviewed separately as to operating eoodltloes, anchors and support points to assure ssfe use of the pipeline. I. Welding Procedure 1. Remove one side clamping serew from each end of the coupling to vent coupling while welding. 2. Check for leakage. 3. turn off the remaining side clamping screws and seal weld the screws to the couplings. Weld the end thrust screws last as they can be tightened to stop Isakage If it develops. 4. Fillet weld coupling ends to pipe with weld of minimum width of 1-1/4 times the pipe wall thick ness. 5. During welding, the temperature of the metal at the gasket surface should not exeed the gasket temperature limits listed In Par. III. C. Thl,, can be checked with temperature indicating sticks and controllsd by welding slowly. Temper ature indicating sticks can be obtained from inspector who Is following the work. High tem perature gasket seals are available for the Weld+fnd couplings. Silicone for up to 500aF., and asbestos mica for up to 1000*F. 6. Special care in welding is required when using half couplings, of sizes 3" and under, which are made by cutting the Weld+nd couplings at mid points. In these sixes, the full coupling is equipped with an inside ring (or sleeve) at the mid-point where the housing (or outer cylinder) Is butt welded. Since the ring and housing are separate parts, it is essential that a complete full-fillet veld be provided at the cut end of the half coupling when it is attached to a pipe line. The weld must join the ring, housing snd pipe all together. 147-4 EM004317 7 . Step* should be tekeo to avoid possible aoveaent of line In coupling beesuee of tbernzl changes or hydraulic shock during welding operations. Such aoveaent could release hydrocarbons during welding operations. 8. Provide at least one 30-lb. chealcal extinguisher and a 1-1/2" fire hose connected and with water at nozzle. 9. In congested areas containing other lines or equipneat, existing pipeline Identification asps and/or piping index should be readily available for use in case of an eaergency. 1*7-5 EM004318 APPBTOIX I Pipe Sites 2" 3" It" 6" 8" 10" 12" lit" 16" 18" 20" 22" 2lt" 30" , Maximal Allowable Pressures /, % Up to 500F Pipe Wall Temperature 1 Prior to Welding) During Weldins'3) After Welding^*' 1690 psig 1050 890 605 *65 370 310 290 250 220 200 180 170 130 350 psig 350 350 350 350 350 310 290 250 220 200 180 170 130 1820 psig 1050 10U0 860 880 600 500 685 600 695 630 580 535 UO ROTES: ^ (2) Where proper coupling seal is used, calculable pressures remain about constant for different temperatures up to 500F, but decrease substantially as temperature is in creased above 500F.

In soae cases, there are no block values to blind gainst at the unit blowdown dru. Where such valves are available, they sometimes leak. Flare lines are generally large, the voluse of gas.contained in theai is large even _ though they are at only several pounds pressure. Hydrocarbon vapors will be released to the atmosphere. The geses they coatsin in many cates contain traces of toxic gsses. This safety standard covers the basic points for the protection of employees blinding flare lines. It is intended to be e general statement of good practices that apply under noraal circuasranees. Use it as a source of Information and as a guide wherever it is applicable. In soae circtatstances, devi ation from these practices may be safe and desirable if the judgment of the Section Supervisors so Indicates. II. PRELIMINARY PROCEDURES A. A review should be aade by Process and Mechanical Super visors to determine which units go to the flare In ques tion. S. A cold work permit shall be issued by Process Operator or Supervisor outlining precautions Hechsnlcal eaployees should tske. C. Unless there is definite evidence that' toxic gates are not present, it should he assuaed they are present. D. Any known leakage into the flare system should be ellalnated if possible. C. Unit Operators of the units servtd by the flare system must be notified when the work is to be done so they ean refrain from controllable releases into the system. Specific EM004329 rn|tnt should k* atl for wnlat cawaleitlou to the job site fra t volt which msy b upset sod foresm a safety value release or seed to pull dews unit pressure to the flare. F. Natural gas blmed-lns should be shut off. C. A fire hose with a fog aorxle shall be provided at the site with water pressure at the souls. E. All bolts shall be free-ruimlag. This ess be dose by removing bolts one at a tlae sad oiling the* or by using aev bolts and nuts. 1. The Fire Department shall be notified. XXI. FRECAPTIOKS A. Where the blinding is to be done at an elevation where there is no permanent platform, an adequate sturdy scaf fold should be provided, complete with handrails. Two or more avenues of egress should be available to those doing the work. B. Where blinding is done, eelf-eouteined breathing appara tus shall be worn. Tbs supply of air lute only 15-20 minutes from the smell cylinders. An alarm is provided oc the sling Psk type which sounds four minutes before the cylinder le empty. Xf one men is to work longer or if more than one man is to work at this location, the full size cylinder (200 cu. ft.) with high pressure hose should be provided. C. Zn order to disperse any gas and ksep the Mechanical em ployees out of a cloud of floanable or toxic ges, an exploeionproof blower or air mover should be used to dilute end drive away the released gas. D. Depending on wind direction, velocity, etc.. It may be necessary to barricade roadways and warn others in ths srss. XV. OTHER CONSIDERATIONS It is preferable to be able to blind against a closed block valve. An evaluation should be made where flare lines must be repeatedly blinded to see if the installation of valves Is justified. If valves are to be installed, it is recommended knife-type valves be installed since they ere more effective in fouling service. Figure 8 blinds should ba used since time is reduced to "turn" the blind. Safety Department Revised Kay 25, 1966 cc: Lists D-8, D-10, D-16 D-20 and D-24 155-2 EM004330 Baton Rome.

Scope The purpose of this safety standard is to outline safety precautions for preventing accidental fires and/or explosions while Making hot work repairs to tank bottoms. With this in ind, the information contained herein will refer only to procedures used for preparing tank bottoms for hot work and docs not Include the preliminary preparations required for tank entry. II. Introduction Special techniques are required in the performance of hot work on tank bottoms to prevent the ignition of flse.^bl<e liquids or vapor that may be entrapped under the tank. Tanks which have contained flaasiable liquids,regard less of age and type of construction, must be con sidered unsafe for hoi work until proper safety inspec tion proves it otherwise. Although each repair Job nusc receive careful individual consideration, the safety procedures described herein provide various methods for pre paring tank bottoms for hot work which may be appli cable to almost any given situation. III. Ceneral Precautions A. The tank must be safely isolated, cleaned and ventilated before authorisation is given to enter and/or perform hot work operations. Reference should be made to applicable tank cleaning standards. B. Visual inspections of the hot work area are necessary. The conditions and safety precau tions under which hot work is to be performed EHO 04331 usc be clearly stated. The person or persona responsible lor authorising the hot work should designate the precautions to be followed. C. A. 1-1/2" fire hose with water pressure to the noxsle and one 30-lb. dry powder extinguisher should be available and ready for instant use. Workmen should be Instructed in the proper use of this equipment. IV. Specific Precautions The specific precautions adopted will be determined by Che condition of the tank bottoa, the type and extent of the hot work repairs to be performed, and inspection results. NOTE: The precautions included in this safety standard are not Intended to cover all the different types of tank bottoa hot work repairs that aay be encountered. They do, however, describe a variety of situations which point out the basic principles of safety that can be applied. A. Tank oust be properly prepared for entry and hot work. B. Work permits for tank entry and hoc work oust be properly signed and Issued before starting work. _ C. Au air never or aovers should be in operation at all tines during entry and hoc work. D. tines to and from the tank should not be dis turbed or dismantled during entry and/or hot work. E. Prior to hot work Che metal surfaces of tanks previously used in TEL service must be sand blasted or power brushed at least 12 inches on each side of heat contact. A hew lead test should be made if tank remains idle more than one week without any work going on in tank. F. Welding machine grounding leads should be attached directly to the tank where hot work is to be performed. 156-2 EM004332 C. Compressed |* cylinder* used for burning opera tion* should be securely fastened in an upright position and kept outside the tank well away free open manholes. Cutting torches and hoses must be shut off at the cylinder valves and removed from the tank when not in use. H. The area Inside and outside of the tank should be kept clear of combustible material. V. Inspection Procedure A standard procedure for the safety inspection of all tank bottoms, as previously mentioned, must be followed regardless of the knowledge of existing or non-existing leaks when hot work repairs are contem plated. A. Approximately 6" diameter openings should be made in the tank bottom in the area or areas where hot work is to be performed to make vis ible inspections and combustible gas tests. B. Cold cutting or drilling with hand or air operated tools is considered safe from an ignition hazard for use in the above operation. Water should be applied to the cutting edge of such tools to reduce the heat of friction. Soil samples and the results of combustible gas indi cator tests taken from the underside of the tank bottom will determine the correct work procedure to be followed. VI. Minor Repairs A. This type of hot work usually involve* the weld ing 'of supports, braces, corrosion pits, patches or other repair jobs localised to email areaa. 1. Drill and tap a 1/2 hole adjacent to the repair area. 2. With metal tubing connect SO lb. CO^ cylinder to the 1/2" tap. 3. Inert underside of tank bottom in the area of welding with CO2 and continue a steady bleed during hot work. 4. Xcmove tubing, plug hole and back weld as required. 156-3 EM004333 VII. Kaior UmIw A. When repair jobs Involving aoit of tha tank bottom ara planned t it nay b daairabla to dis place Cbe flwible liquid and/or vapor by water flooding. 1. Drill and tap 1/2M holes In the bottoa of the tank at high points sufficiently spaced to assure proper inspection and disperseaeat of water. 2. Install pipe nipples In these holes to be used as vents, check points and for the application of water. Height of nipples should exceed the dike Motioned in 3 below. 3. Construct an earthen dike around the tank's outer shall higher than the highest floor plate. 4. Fill space under tank bottom with water. Continue flow of water to Mintaln a con stant high water level within the dike. 5. Hatch for leaks and tewporarily plug with clay or asbestos as necessary to keep tank bottoa dry. 6. After repairs are coupleted, remove nipples, plug and back veld as required. VIII. Perimeter Repairs A. Kepalrs around the periphery of a tank bottoa may be aade safely after the following preparations: 1. Excavate under the tank edge. Such excava tions should extend a ainlaua of 12 inches beyond the point of any hot work area and aust be large enough for a aan to work in with safety and coafort. 2. Seal off all openings between the floor places and the tank foundation by packing with aud, asbestos or some other suitable Mterial. 3. Use a combustible gas indicator to check floor place, tank foundation seals, and excavations. 156-4 EM004334 4. A portable air blower may b used for ventiiatioo purposaa. U. Sectional Repair* A. When making sectional repair* to tank bottoats, the following Method* may be waed: 1. With hand or air-operated tool cold cut and renove the section of tank bottoa to be replaced. Water should be applied to the cutting edge of such tool* to reduce the haat of friction. 2. Remove earth froa under the section to be replaced. Seal the perlMeter of pateh area with mud. clay, asbestos or other suitable non-corrosive material. Fill with sand. 3. Use a combustible gas indicator to be sure an effective seal has been made. 4. When hot work is being don* in the course of Installing a new section, maintain an inert atmosphere under the patch area, this may be accomplished by using a CO2 cylinder or dry ice. X. Double Bottoa Installation A. When constructing a double bottom in a tank, the following procedure* are considered a standard safe practice. 1. With air or hand operated tools drill and tap 1/2'* holes in the tank bottoa sufficiently spaced to permit proper inspection. 2. If combustible gas indicator tests prove tank bottom is gassy, purge with steam, water, air or other suitable means until gas-free. 3. Place at least four inches of hoc road mix asphalt over existing floor. 4. Install new bottoa by welding.

There are sound and correct practices regarding the use of electrical safety tags at Baton Rouge. Unless Instructed otherwise by his supervisor, an employee shall follow these prac tices. I. Why do we use safety tags? Safety tags are sentinels which warn all persons not to close circuits which are tagged open. Tags protect lives and property. II. What types of safety tans are used? Two types are used - the white "BARGER" tag and the red "BANGER - HOLD" tag. Each of these tags is designed for a specific use as described below. Tags other than these two types are not used as electrical safety tags. No electrical safety tag is used a second tine, but is des troyed wh.<t -ecc'.'sd. Electrical safety tags are stocked in all tool rooas. III. Responsibility for Tagging White Red Whlte"DAKOER" Tans for Mechanical Work on Elec trically Driven Equipaent. The white "DANGER* tag is used when mechanical work is done on electrically driven equipaent. This includes inspection work such as climbing on or handling moving parts. Responsibility for such tagging lies with the operators of the equip ment, and they normally perform the tagging Red "DANCER - HOLD" Tags for Electrical Work on Electrical Equipment or Circuits. When electrical work it to be done on electrical equipaent or circuits, the equipaent or circuit oust be tagged out. The red "DANGER - HOLD" tag is used. Responsibility for the tagging lies with the operators of the equipment and with the employee per forming the work. Tagging shall be done by the employee performing the work. EM004336 White Red operation. Any employee who My be exposed to in jury by the electrical equipment starting should assume some responsibility by asking sure that the equipment is properly iso lated and tagged. IV. Responsibility for Removal of Tar Tags are removed alter definite proof is established that all personnel and equipment are in the clear. Those res ponsible for removal of tags are: White Red 1. The signer of the white "BARGER" tag (the em ployee who tagged the circuit) may remove it. 1. The red "BARGER - KOLB" tag can be removed only by the employee who signed and Installed it. 2. When the signer is not im mediately available the white "BARGER" tag may be removed by operators of the equipment, by quali fied employee or by supervisors. V. Placement of Safety Tags on Equipment The main switch or circuit breaker is to be opened and the operating handle, lever, or control switch tagged. Tagging pushbuttons, pressure switches or other pilot devices does not give absolute protection and is prohibited. These de vices are in the low voltage control circuit and not in the main high voltage power circuit. White Red When HECHARICAL WORK is to be done on motor driven equip ment, the motor shall be shut down in the normal manner, and the white "BARGER" tsg attach ed to the circuit breaker op erating handle. If the equip ment is supplied by 2*400-volt switchgear located in sub- Vhen ELECTRICAL WORK is to be done on circuits or equipment, the circuit breaker or switch supplying the circuit or equipment is opened in the normal manner, and the red "BARGER - HOLD" tag is then filled out and attached to the 157-2 EMO 04337 White statloot, or toy SkOO-rolt cubicle or tank type starters* the motor shall toe shut down is the norael manner, and the instructions oa the blue and yellow plate attached to the atartin# equipment fol lowed. Operators shall not opes any doors or panels oa aotor starting equipment. Precautions after Tagging 1. Before working on the equip ment powered toy the circuit or before giving assistance to others who have to work on sueh equipment, try the pushbutton or other con trol devices provided to be sure that the euqipment will not start. Red switch or breaker operating handle by the employee doing the work. If the circuit or equipment is supplied by switchgear type breakers* the breaker is opened in the normal manner* when the control circuit is de energised toy opening its switch or pulling the ruses. After checking the circuit to aske sure it is de energised, the disconnects are opened, or the circuit breaker lowered* as the case may be* and the red "DAXGER - BOLD" tag is then filled out and attached to the control switch handle toy the employee doing the work. 1. Before working on the circuit or associated electrical equipment* teat for voltage. Be mure your testing device is working properly. Try it on a known live cir cuit whenever possible. 2. Ground the de-energised circuit before working on it where possible. 3. Where a motor is removed for'repairs, bond the power leads securely together with a bolt and tape with a few layers of tape. This creates a short and prevents the possibility of energised leads being exposed. 15T-3 EM004338 VXX. The Use of Safety Tiw The White "DAJK5ER" The The Bed "MIOZS - BOLD" Tic 1. When Pied 1.
