INDUSTRIAL HYGIENE DIRECTIVE July 27, 1988 . ASBESTOS DEMOLITION AND REMOVAL It is the policy of Reynolds Metals Company that all employee exposures to asbestos be kept as low as possible. Consequently, where feasible, all asbestos demolition/removal work should be performed by qualified outside contractors. A list of qualified contractors and a Performance Audit Form are enclosed. The Performance Audit Form should be returned to the attention of R. E. Benton, Industrial Hygiene, upon the completion of each job. For small-scale asbestos demolition/removal jobs, where time is critical and a contractor cannot be obtained, properly trained RMC employees may perform the asbestos demolition/removal work. These employees, however, must be thoroughly trained on proper work practices for handling asbestos. (See Appendix A.) Part of the training program should include videotapes which are available from Corporate Industrial Hygiene. Employees must also be advised about the types of asbestos present and their potential health effects. At least one supervisor should attend an asbestos training course, if the plant anticipates using Reynolds' employees for any asbestos demolition/removal work. Training courses are sponsored by the Environmental Protection Agency (EPA) Asbestos Training Centers and other groups. (See enclosed list of training centers in Appendix B.) The supervisor who attends the course would then be responsible for training all affected plant personnel, to ensure that proper work practices are used during all asbestos demolition/ removal jobs. Air sampling is also required on all asbestos demolition/ removal jobs, to assure the effectiveness of the controls and work practices. This requirement may necessitate the purchase of air sampling equipment. (See Appendix C.) Should the plant wish to purchase equipment, please contact Ron Benton (Ext. 2265) or me (Ext. 3506), regarding the type of equipment recommended and its proper use. From an environmental standpoint, EPA's National Emission Standard for Hazardous Air Pollutants (NESHAP) for asbestos dictates: 1) agency notification of planned demolition and renovation activities, 2) adherence to specified procedures for asbestos emissions control during removal activities, and 3) proper handling and disposal of the asbestos materials at the landfill site. These standards are applicable to the renovation and/or demolition of friable asbestos. Please notify C. R. Bent (extension 2918) of the Corporate Environmental Control Department, when asbestos removal activities are planned, to determine the applicability of the NESHAP regulations and/or to discuss the specifics of these requirements.

This appendix dtsenbes these controls and work practices in detail Preparation of the Area Before Renovation or Maintenance Activities The first step in preparing to perform email-scale, short-duration asbestos renov ation or maintenance task, regardless of the abatement method that will be used, is the removal from the work arcs of all objects tbst are movable to protect them from asbestos contamination Obiects that cannot he removed mutt be covered completely with a S-mil thick polyethylene plastic aheeting before the task begins If objects have already been contaminated, they should be thori-iighlv cleaned with a High Efficiency Particulate Air (IIEPAj filtered vacuum or be wet wiped before they are removed from the work a-re nr completely encased in the plastic. II'Cl Methods Wherever feasible, and tegardless of the abatement method to be used (e g. removal, enclosure, use of glove bags), wet methods must be used during small-scale, shun duration maintenance and renovation activities that involve disturbing asbestoscontaining materials Handling asbestos materials wet is one of the most reliable methods of ensuring that asbestos fibers do nut become airborne, and this practice should therefore be used whenever feasible. As discussed in the Summary and Explanation acction of the preamble for paragraph (g). Me thods of Compliance, wet methods can be used in the grtt maiority of workplace situations Only in cases where asbestos work must be performed on live electrical equipment, on live steam lines, or in other areas where water will senously damage materials or equipment may dry removal be performed Amended water or another wetting agent should be applied by means of an airless sprayer to minimise the extent to which the xsbestos-conttimng material is disturbed. Asbesios-contsining materials should be wetted from the initiation of the maintenance Clove Bag Installation Clove begs are approximately 40-uich-wide times M-inehlong bogs fitted with arms through which the work can be performed (tee Figurt C-HAIJ.

Removal of Smell Amount of AsbestosContaining Materials Several methods can be used to remove small amounts of asbestos-containing materials during small-scale, short-duration renovation or maintenance tasks These include the use of glove bags the removal of an entire asbastos-covered pipe or structure, and the construction of mini-enclosure*.

Clove Bat Work Practices The proper use of glove bags requires the following step*: (1) Clove bags must be installed so that they completely cover the pipe or other structure where asbestos work is to be done. Clove bags ire installed by cutting the sides of the glove bag to fit the size of the pipe from which asbestos is to be removed. The glove bag e attached to the pipe by folding the open edges together and securely aealing them with tape. Ail opening* in the glove bag musi be sealed with duct tape or equivalent material The bottom seam of the glove bag must also be sealed with duct tape or equivalent to prevent any leakage from the bag that may result from a defect in the bottom seam (Figure C--1(B)). (2) The employee who * performing the asbestos removal with the glove bap must don s half mask dual-cartndgt HEPAquipped respirator respirators should be worn by employee* who sre ui close contact with the glove beg end who may thui be exposed as a result of small gaps in the asms of the bag or holes punched through the bag by a razor knife or a piece of w ire mesh. (3) The removed asbestos material from the pipe or other surface that has fallen into trie enclosed bag must be thoroughly wetted with a wetting agent (applied with an airiest prayer through the pre-cut port provided in most gloves bags or applied through a smell hole cut in the bag) (Figure C-l(CJ) (4) Once the asbestos material has been thoroughly wetted, it can be removed from the pipe, beam or other surface The choice uf tool to use to remove the asbestos-containing material depends on the type of material to ba removed Asbeatos-contaimng materials re generally covered with painted canvas nd/or wire mesh Painted canvas can be cut with razor knife and peeled away from the asbestos-containing material underneath. Once the canvas has been peeled aws>. the asbestos-containing material underneath may be dry. in which cate it should be re-sprayed with a wetting agent to ensure that it generates as little dust as possible when removed. If the aabeitos-containing material la covered with wire mesh, the mesh should be cut with nips, tin snips, or other appropriate tool and removed. A wetting agent must then be uaed to spray any layer of dry material that is exposed beneath the mesh, the surface of the stripped underlying structure, and the inside of the glove bag. (5) After removal of the layer of aabesioeeontaining material, the pipe or surface from which asbestos hat been removed must be thoroughly cleaned with a wire brush and wet wiped with a wetting agent until no Irecat of tha aabeatoa containing aiatanal cun be teen. (6) Any asbestos containing insulation edges that have been exposed as a result of the removal or maintenance activity mutt be encapsulated with bridging aneapaulant to ensure that tha edges do not release asbestos fibers to the atmosphere after the glove bag bat been removed. (7) When the asbestos removal and encapsulation have been completed, a vacuum hose from a HEPA filtered vacuum must be inserted into the glove bag through the port to remove any air in the bag that may contain asbestos fiber* When the nr hat been removed from the bag. the bag should be squeezed tightly (at dote to the top as possible), twisted, and scaled with tape to keep the asbestos mtterisit safely in the bottom of the bag The HEPA vacuum can txtiner RMC0086302 003618 A-2 then be removed from the bag end the glove bt| itself can be removed from the work area to be disposed of proper!)

Although glovebags can be fabricated by the user for each project, most contractors prefer to purchase readymade bags. The size, quality, style, and cost vary depending on the manufacturer. In addition to the glovebag, several other tools and materials are commonly required to perform the project successfully. These materials, listed below, are readily available from most asbestos abatement contractor suppliers. MATERIALS 1. Glovebag (one or more, depending on project size) 2. Pump-up garden sprayer (2-3 gallon size) 3. Amended water (surfactant, availble from local garden shop or safety supply company) 4. Duct tape (3-inch width) 5. Polyethylene disposal bags (6 mil) 6. Smoke tubes with aspirator bulb 7. HEPA-filtered vacuum cleaner 8. Bone saw 9. Utility knife with retractable blade 10. wire cutters 11. Tin snips (if aluminum jacket is present) 12. Polyethylene plastic (roll of 4 or 6 mil) 13. Dual cartridge respirators with high efficiency cartridges 14. Disposable full-body suits with hood and feet covering 15. Small scrub brush 16. Stapler 17. Several rags 18. Wettable cloth 19. Asbestos caution signs and labels 20. Reinsulation materials, as necessary BEFORE STARTING A GLOVEBAG PROJECT Two persons are required to perform a glovebag removal project. Also, a third person is sometimes available, to assist with supplies, to keep unwanted visitors out of the area, and to conduct air monitoring. Each of the team members should be trained on the use and limitations of glovebags. They should also be included in the respiratory protection and medical surveillance programs. Before any work begins, all necessary materials should be brought into the work area. The work area should be roped off and warning signs should be posted on the perimeter to minimize the chance of visitors entering the area. Barrier tape (3-inch) with a pre printed asbestos warning is recommended. If applicable, the HVAC supplying the work area should be shut down. Employees should also be trained about emergency procedures, in the event of a glovebag rupture. The emergency training should cover wet cleaning, HEPA vacuuming procedures, and shower use. The following guidelines may be used for most pipe lagging projects: 003621 txtiner RMC0088305 A-5 ASBESTOS DEMOLITION AND REMOVAL July 27, 1988 REMOVAL PROCEDURES 1. Follow the manufacturer's directions and mix the surfactant with water in the garden sprayer. 2. Each employee should wear a cartridge respirator and check the face-fit. 3. Each employee should wear a disposable full-body suit, being mindful that the hood goes over the respirator straps. 4. The pipe on which the work will be performed should be checked. REMEMBER...NEVER PERFORM GLOVEBAG REMOVAL ON HOT PIPES OVER 150 F. This may cause the bag or gloves to melt over the workers' hands and arms. If the pipe is damaged (broken, lagging, hanging, etc.), the entire length of the pipe should be wrapped in polyethylene plastic and "candystriped" with duct tape. A common problem with glovebag work is that loose pipe lagging several yards from the glovebag may be jarred during the work, causing a release of asbestos into the air. Another problem is failure to clean up debris on the floor and other surfaces. If the pipe is undamaged, it is still necessary to place one layer of duct tape around the pipe at each location where the glovebag will be attached. This serves two purposes. First, it gives a good surface on which to seal the ends of the glovebag. Second, it minimizes the chance of releasing fibers when the tape at the ends of the glovebag is peeled off at the comple tion of the job. 5. Slit the top of the glovebag open (if necessary) and cut down the sides to accommodate the size of the pipe (about two inches longer than the pipe diameter). One brand has a zipper top and straps at each end facilitating installa tion of the bag on the pipe. 6. Place the necessary tools into the pouch located inside the glovebag. This will usually include the bone saw (flexi saw), utility knife, rags, scrub brush, wire cutters, tin snips, and wettable cloth. Note: It is easiest to pre-cut the wettable cloth at this point. Cut out a donut shape with the inner diameter 1/2-inch smaller than the diameter of the pipe beneath the in sulation. The outer diameter of the donut should be three inches longer than the diameter of the pipe in sulation being removed. Finally, cut a slit in each of the two donuts, so they can be slipped around the pipe. 7. Place one strip of duct tape along the edge of the open top slit of the glovebag for reinforcement. TX TIMER RMC0086306 003622 A-6 ASBESTOS DEMOLITION AND REMOVAL July 27, 1988 8. Place the glovebag around the section of pipe to be worked on and staple the top together through the reinforcing duct tape. Staple at intervals of ap proximately one inch. This should provide an ade quate seal along the top. Next, duct tape the ends of the glovebag to the pipe itself, previously covered with plastic or duct tape (See Step 4). 9. A smoke tube and aspirator bulb are needed to test the glovebag. Place the tube into the water sleeve (two-inch opening to glovebag). By squeezing the bulb, fill the bag with visible smoke. Remove the smoke tube and twist the water sleeve closed. While holding the water sleeve tightly, gently squeeze the glovebag and look for smoke leaking out, especially at the top and ends of the glovebag. If leaks are found, they should be taped closed, using duct tape, and the bag should be retested with smoke. 10. Insert the wand from the water sprayer through the water sleeve. Using duct tape, tape the water sleeve tightly around the wand, to prevent air leakage. 11. One person should place his hands into the long-sleeved gloves, while the second person directs the water spray at the work. 12. If the section of pipe is covered with an aluminum jacket, it should be removed by first using the wire cutters to cut any bands and then using the tin snips to remove the aluminum. It is important to fold in the sharp edges to prevent cutting the bag when it is placed in the bottom. Use caution to prevent cuts - these edges are sharp 1 13. With the insulation exposed, use the bone saw to cut the insulation at each end of the section to be re moved inside the glovebag. Note: A bone saw is a serrated heavy-gauge wire with ring-type handles at each end. Throughout this process, water is sprayed on the cutting area to keep dust to a minimum. 14. Once the ends are cut, the section of insulation should be slit from end to end, using the utility knife. The cut should be made along the bottom of the pipe and water continually supplied. Again, care should be taken, when using the knife, not to puncture the bag. Some insulation may have wire to be clipped, as well. 15. Spray all tools with water inside the bag and place back into pouch. 16. The insulation can now be lifted off the pipe and gently placed in the bottom of the bag. TXTINER RMC0086307 003623 A-7 ASBESTOS DEMOLITION AND REMOVAL July 27, 1988 17. Using the scrub brush, rags, and water, scrub and wipe down the exposed pipe inside the glovebag. Note: The inexpensive horse rub-down mittens work well for this. 18. Wet the donut-shaped pieces of wettable cloth over the exposed ends of insulation remaining on the pipe. Wettable cloth is a plaster impregnated fiberglass webbing available at many hardware and/or plumbing supply stores. 19. Remove the water wand from the water sleeve and at tach the small nozzle from the HEPA-filtered vacuum. Turn on the vacuum only briefly to collapse the bag. 20. Remove the vacuum nozzle, twist the water sleeve closed, and seal it with duct tape. 21. From outside the bag, pull the tool pouch away from the bag and twist it to separate it from the bag. Place duct tape over the twisted portion and then cut the tool bag from the glovebag, cutting through the twisted/taped section. 'This will allow the contami nated tools to be placed directly into the next glovebag without cleaning. Alternatively, the tool pouch with the tools can be placed in a bucket of water, opened underwater, and the tools cleaned and dried without releasing asbestos into the air. Note: Rags and the scrub brush cannot be cleaned in this manner and should be discarded with the asbestos waste. If more than one adjacent section of pipe is to be removed, the glovebag may be loosened at each end and slid along the pipe to the next section. In this case, the tools would remain in the bag for continued use. 22. With the removed insulation in the bottom of the bag, twist the bag several times and tape it to keep the material in the bottom during removal of the glovebag from the pipe. 23. Slip a 6 mil disposal bag over the glovebag (still attached to the pipe). Remove the tape, open the top of the glovebag, and fold it down into the dis posal beg. 24. Remove the disposable suits and place these into the bag with the waste. 25. Twist the top of the bag closed, fold this over, and seal it with duct tape. Then put a warning label on the bag. 26. Using a clean damp rag, wipe the exterior of the respirator and leave the work area. Then, remove the respirator. 003624 A-8 TX TINER RMC0086308 ASBESTOS DEMOLITION AND REMOVAL July 27, 1988 27.

The preferred collection device shall be the 25mm mixed cellu lose ester filter in a cassette with an open-faced 50mm extension cowl. The 37mm cassette may be used in those situations where dust loadings reduce the sampling time to less than one hour. (See Item 3, below.) 2. An airflow rate between 1.5 liter/min. and 2.5 liters/min. shall be used for either the 25mm or 37mm cassette. 3. If, during sampling, the filter darkens noticeably (i.e. changes color), or if loose dust is seen on the filter, a second sample shall be started. 4. All pumps should be calibrated with a bubble flow meter before and after each day's use. An inverted 500ml buret will suffice as the bubble meter. 5. Before starting the sampling, record the date, plant name, sample number (written on the white shrinkband), pump number, employee's name, work description, and controls used on the enclosed sampling data sheet. Also, note the type of protective clothing and respirator worn by the employees. 6. The tubing from the pump should be attached to the end of the cassette that has the "ribbed" appearance. The cassette should be sampled with an open face (i.e. entire cap removed from the end of the cassette, rather than the small plug) and attached to the worker's shirt collar. 7. After the pump is turned on, ensure that it is functioning properly and has an 8-hour charge. The time the pump is started is also recorded on the sampling data sheet. 8. Unless the filter darkens, as in Item 3, the sampling period should be a series of 4-hour samples until the project has been finished and clean-up completed. At the end of each sampling period, the cassette should be removed from the tubing, the end cap and bottom plug replaced, and the time pump stopped should be recorded on~the sampling data sheet. 9. During sampling, any conditions which might affect the results should be noted on the sampling data sheet (e.g. glovebag rupture, insulation not kept wet, etc.). 10. After sampling has been completed, each cassette should be taped around the ends, to prevent accidental opening during shipment, and returned to Corporate Industrial Hygiene in a rigid container, along with the completed sampling data sheets. (Note: One unused cassette should be returned as a blank, for every 6 filters used.) *** 003629 C-l TX TINER RMCOO80313
