Introduction IIJERTEEN is b synthetic transformer dielectric fluid made by the chlorination of a chemical, biphenyl, to give it non-flarmable ^properties. Since this process stabilizes the fluid for transformer use, it also makes it difficult to destroy when it gets into the environment. Tests have been made throughout the world that show the undesirable nature of this type of fluid and its effect on sane species of fish and birds. It has been shown that if IHERTEEW is to continue to be used in transformers and capacitors, a positive effort must be made to control and prevent pollution by this product. INERTEEN can get into the environment during the manufacture, delivery, improper use, maintenance, repair and disposal of trans formers and capacitors. Experience has shown that it is necessary to control all aspects of the manufacturing and fluid handling process with emphasis on the possibilities of leakages and spil-lages to prevent any INERTEEI from getting into the environment. Close attention to good plant housekeeping is the main key to pollution control. Care must also be exercised to ensure that all test samples and HIERTEEN contaminated solvents are collected for disposal in an acceptable manner. Chemicals, such as INERTEEN, are ROT PERMITTED in any effluent from manufacturing plants. This is prohibited by the clean stream ; laws, IliERTESN and HfERTEEH contaminated wastes have been shown not to be acceptable in sanitary land-fills. This then requires that thesejM>'*a vastes must be destroyed by incineration in a high temperature incinera tor ( 7) equipped with a scrubber. ' .. This problem is extremely serious as evidenced by the proposed federal legislation attempting to ban its use, By following acceptable procedures the problems of any pollution of the environment by INERTEEN from our plants can be controlled. II. General Safety Precautions ~ :---- ------------i .* * INEpTEEN vapor is non-toxic to humans7, except if taken internally, but care.must be taken to avoid unnecessary contact with the liquid or vapor t A. Vapors * The odor of INERTEEN is noticeable well below the maximum safe acceptable air concentrations. The maximum, atmospheric concentra tion limit (8 hours) recorsr.cnded is one milligram of INERTES! per cubic meter of air. NPC00026254 753591 High concentrations of INERTEEN such as found inside a trans former tank or the vapors from hot INERTEEN must be avoided. The high concentrations of vapors can cause irritation of the eyes, nose, throat and upper respiratory tract. If contact with* high concentrations of EIEKTEEN is necessary an approved gas mask or self-contained breathing apparatus must `be worn. The [vaporb produced when JHEETEEH is decomposed by very hich temperatures or from an electric arc will consist mainly of hydrogen chloride. This vapor is very unpleasant and irritating, thus giving ample warning of its presence. Under emergency conditions an approved gas mask or self-contained breathing apparatus must be worn in order to enter a space containing vapors of decomposed INERTEEH. If irritating odors are detected with the breathing apparatus in use, the person should go Irenediately into fresh air. All gas masks, respirators, replacement cartridges, and selfcontained breathing equipment must be Bureau of Mines approved and be maintained on a regular schedule in accordance with the manufacturers recommendation. Fluid Unlike oil, INERTEEN has virtually no fire hazard. However, INEKTEEN can be irritating to the skin. Seme people are quite allergic to the solvent action of INERTEEN on the skin. Both the liquid and vapor are irritating to. the eyes. To prevent direct contact with the fluids approved aprons and gloves should be worn, however, the regular use of gloves is not reccoaended .since the gloves are easily contaminated on the inside with INERTEEK frem the hands. t After handling INERTEEN. the hands should be washed thoroughly with warm soapy water. In the case of spillage onto clothing, the clothing should be removed as soon as practical and laundered or discarded in containers designated as ''Scrap Burnable INERTEEN Waste". a Eye Protection INERTEEN and its vapor are irritating ;to the eyes. Eye protection such as safety glasses with side shields or face shields must be worn at all times when handling INERTEEN. The use of medicinal Ushe'p or detergents on the skin followed by an application of skin cream will eliminate any irritationsresulting from INERTEEN coming in contact with an open cut or* abrasion. Eye exposure-to liquid IKSRTEEN shou3d be irrigated, dinnediately with large quantities of water frea an approved eye -2- NPC00026255 753592 i. wash for flfLr.en minutes and then examined by the company physi cian. Persons developing a shin Irritation due to coniact with IKERTEEK should be examined by the company physician. P, Inrcstlon of Ib'ERTEF.?? IKERTEEK is moderately toxic if taken internally. Swallowing an ounce or more will cause irritation of the digestive tract and Internal reaction* In such cases the person should go to * the company physician inenedlately. Any condition that might result in a possible ingestion of IKERTEEK should be avoided. /* i Ill, Receiving And Storage Of IKEKTEEK ! 1KERTKEN is shipped from the manufacturer in tank cars, tank . trucks, 55 gallon steel drums and in 5 gallon metal drums. All containers must be labeled as to contents and carry a precaution- " ary label in reference to its .environmental hazard. Every container should be inspected for this labeling and leaks when received, .. A. Tank Car Receiving . . i v-- ^ ---- --------- ",% A spec ini receiving area must be allocated to IKERTEEK tank cars.

Respirators, self-contained breathing apparatus, or gas-masks of Jo type approved by thy Bureau of Mines' must-be available* for use by pcrsounci in high air concentrations of INERTEEN. All manufacturing procedures must be directed toward preventing loss of INERTEEN to the environment. In case of <111 INERTED NPC00026257 753594 spill the Superintendent of Maintenance should be contacted Irncdlatcly to carry out the prescribed clocn-up procedure, B. Special Containers 1'or Br.rnn Materials 1. Drums lnbelcd "Scrap IKERTEEN" must be available for handling all .spills and waste IKERTEEN from the sump, failed units, drip pans, sample Jars etc. 2. Open-head drums with approved closure or other suitable con tainers labeled "Scrap Burnable IKERTEEN Materials" must be *available for handling scrap cellulose insulation, rags, paper pressboard, wood, sawdust, etc, 3. Separate containers for handling steel, copper, end aluminum, each adequately marked, shall be provided for the components of contaminated core and coil assemblies when tear downs arc necessary* 4. Containers for supplies of sav-dust for absorbing small IKERTEEN spills or clean-up must be provided. Speedy-dri or ^ other clay absorbing materials are not recommended. i...m *-'- CondlClonlng IKERTEEN A. IKERTEEN Conditioning Seulement The conditioning equipment and Intermediate storege tank should be located in the bulk storage area which is provided with an adequate curb to contain the INERISEN held in the intermediate storage tank. Two alternate procedures are satisfactory. The conditioning equipment*and intermediate storage tank may be located in the manufacturing filling area since a curb is provided for con taining a spill. If the conditioning equipment and storage tank is located in other areas it must be placed on a cement , floor with an adequate curb surrounding the equipment and tank to provide a holding basin for afl the IKERTEEN in the intermediate storage tank.In the event of a tank failure. A sump, not connect ed to a storm or sanitary sewer*, may be provided to clean the holding basin In case of a spill. An alternate would be separ- ' ate pumping equipment to pump the IKERTEEN spill into "Scrap ... 1NERTEEN" drums for disposal, * B, Fullers1 Earth Conditioning of IKERTEEN requires .fullers' .earth treatment. .The spent fullers' earth in cartridges or bags when replaced shall, be allowed to thoroughly drain over drip*pans- to remove as muchliquid IKERTEEN os possible. The cartridge units of steel mesh la 1 NPC00026258 753595 construction containing fullers* earth shall be scrapped in the containers marked, "Hteel Contaminated with INERTES!I, for dis position. Cloth bags filled with spent fullers* earth shall be disposed of in the containers 'marked "Scrap Burnable IERTEE Waste". The fullers' earth in the conditioning equipment shall be changed when necessary to maintain the THIRTEEN within acceptable operating limits. . VI. .Tear-Down of IIIERTCEN Units for P.enair or Scrap A. Tear-Down Procedure 1. Drain all the INERTEEN freon the transformer or capacitor into the conditioning tank or into drums labeled "Scrap INERTEEli" depending upon the laboratory reports of the condi tion of the INERTEEN. Allow sufficient time for all the INERTEEN to drain from cores and colls (at least twelve hours) and again drain the INERTEEN from the tank, 2. Remove the cores and/or coil assemblies from the tank and place them on a steel tear-down table having a raised edge to contain any run-off INERTEEN frem the assembly. A center or other properly located drain shall be provided in the steel table to collect the run-off IKERTEEN. 3. The personnel that dismantle the unit mist wear approved gloves, apron and eye protection. % U. place all materials in the appropriate salvage containers during the teor-down for later disposition. 5. The tear-down table shall be cleaned with kerosene or other approved solvents after the dismantling operation. She used fluids shall be placed ,in the "Scrap BIERTEEK" drums for dis position. VII. handling of Empty Containers Contaminated with IUERTEEK A. Tank Cars * When tank cars have been unloaded they will "be re-sealed and returned to the manufacturers without further cleaning. These tank cars are used only for INERTEEN shipments and the cleaning will be done by the supplier.. B. Drums Drums which contained new IKERTESN can be used for waste fluids - 6- NPC00026259 753596 trom the INERTEEN manufacturing section and should be plainly marked "Scrap lliERTEEN". Drums which must be retired from use shall be washed twice with one gallon portions of kerosene, benzine, or other approved solvent before crushing, delivery to scrap dealers or used for other disposal. The wash fluid shall be disposed of in drums marked "Scrap INERTEEtf'. C. 5-Gallon Drums 5-Gallon drums which contained new INERTEEN when empty shall be washed twice with kerosene, benzine or ocher approved solvent before scrapping or re-using. The wash solvent shall be placed in a "Scrap IKERTEEK" drum. D. Sample Bottles Sample bottles and other small containers used for obtaining samples of INERTEEN for test from any source such as trans formers, storage tanks, filling lines etc. must be rinsed at least twice with benzine or kerosene before re-use or scrapping. The rinse solvent shall be placed in a "Scrap IKERTEEN" drum. VIII. Purchases Of IKERTEEN Bv Manufacturing Divisions. K & R Plants And E & S Groups No direct sales of any quantity of INERTEEN will be made to any customers nor will authorizations be issued to the Monsanto Company to ship INERTEEN except to those locations manufacturing INERTEEN equipment or M & R Plants and E-& S Groups having repair or service orders for the direct use of IKERTEEN under tht super vision of Vestlnghouse personnel. This is to eliminate any possible chance for INERTEEN to be obtained for uses, of any kind except in transformers or capacitors. A. 'Manufacturing Plants INERTEEN for use in manufacturing and filling new equipment will be ordered from the Monsanto Company as a stock material. Orders for IKERTEEN for make-up or other purposes will be re ferred to the nearest M & P Plant or E & S Group depending on the need for the INERTEEN. B. District Offices * Orders for INERTEEN will be referred to the nearest M & R Plant or E & S Group depending upon the need for the INERTEEN and ' will be made a part of a service contract on specific equipment. C. M It R Plants Orders for INERTEEN for use in repairing equipment will be issued -7- NPC00026260 753597 by the M & R Plants to Monsanto for shipment to the repair plant' only and must be used on customers orders. All repair shops performing service work on IKERTEEN transformers must set aside mt ares in the repair shop to handle all IKERTEEN service work. This shop area must be altered to provide the same safeguards as established in the manufacturing locations including curbing around the area to contain an accidental spill, containers for holding materials contaminated with INERTEEN, containers for scrap IKERTEEN and safety equipment for employees. All scrap materials must be disposed of at authorized locations that have incinerators capable of safely destroying the IKERTEEN. Only the INERTEEN contained in the equipment will be returned to the jcus.toraer. D. E & S Groups Service orders to maintain IKERTEEN equipment will be accepted and the necessary IKERTEEN will be ordered by the E A S group from Monsanto Co. for shipment to the E & S facilities. The required IKERTEEN will be taken to the customers premises and additions of make-up as other requirements supervised. An excess IKERTEEN will be returned to the E & S storage area.

Purchases of INERTEEN bv District Offices and Repair Shoos It is necessary to police the sales of INERTEEN to all users in order to prevent the misuse of INERTEEN by those requiring this mater ial for equipment or applications which are not closed systems thus permitting environmental contamination with the INERTEEN. * A. District Offices All orders for*INERTEEN must be carefully surveyed In order to establish the application for which material will be used. It is dccLrablc, if at all possible, to obtain a service contract to handle the repair or maintenance of the customers' transformer rather than supply the INERTEEN. This insures direct control to prevent tlve. pollution of the environment. For those customers willing to provide a service contract, it is important that the j work is performed by personnel knowledgeable in the proper handling of INERTEEN -under the newly established guidelines. Orders for INERTEEN1 for the service contracts shall be placed with Monsanto for delivery to the servicing group and not to the customer. In those eases in which customers insist on performing their own . maintenance and repair work and in locations where service con- .,,tracts arc impractical, 'orders for INERTEEN will be accepted only `ofter the customer has established the ncc4 for the INERTEEN and will provide signed documents indicating they are fully aware of .the polychlorinated biphenyl problem, that they have established -7- NPC00026262 753599 procedure* for the. proper lwin<11Irp. of INERTEEN and thet they in no viiy will hold the ip,house Electric Corporal ion re sponsible for liability rrfiul ling iron their use of the INERTEEN.
