"ANSI C-107 1st Draft Proposal fo r February 0 , 1972" CAPACITOR PLANT HOUSEKEEPING AND EMPLOYEE SAFETY The following procedures and lim its are Intended to be minimum require- ments to be met by manufacturers o f capacitors using polychlorinated biphenyl. Handling, control and disposal procedures are given, together with exposure :11m1ts and Indicated antidotes and cleanup procedures. .' 1. . M aterlal. Chlorinated biphenyl for use In capacitors sh all consist o f chlorinated homologues and Isomers o f biphenyl not exceeding the"tabulated values: Pentachloro (and higher 1 chlorine) Tetrachloro Trlchloro ( and lower 2 chlorine) .403 15.003 (Balance) Solvents Include benzene, kerosene, acetone, amyl alcohol, e th e r, and chloro form. Other typical p roperties are: Flash p o in t, Cleveland open cup: 177C, minimum D istilla tio n Range: 10% below 323eC; 90S below 356C Specific Gravity: 1.362 to 1.372, a t 25*C/15.5C Vapor Pressure 0C * 0.001 rrcn 25C * 0.006 mm ( e s t.) 150C 4.3 mm 200C = 29.0 inn i At 25C and 760 mm Hg pressure, Saturated a i r contains O. 1 m q/l1ter * 98.8 ppm) (l ppm 0.010 m g/l1ter) m h/H ter. 2. Bulk flu id shipment, receiving, and tra n sfe r: Shipment o f polychlorlnate biphenyl from point of manufacture to point o f receiving sh a ll be done 1n closed containers: ra il tank c a rs; truck tanks; marine or barge tanks; o r sealed drums. Containers shall be lab elled as to contents, and carry a precautionary label again loss of fluid to the open environment. Containers used fo r transport of poly- 906219 BBRN003H72 2 chlorinated biphenyl shall not be used for storage or tran sp o rt of other material without being completely cleaned of a ll traces of PCB. (Cleaning procedures must 0 take cognizance o f precautions against excessive exposure and o f the need for pro* per disposal o f contaminated cleansing solvents and m aterials s e t forth below.) Transfer from shipping container to processing system sh all be through closed piping or tubing with appropriate valves, pumps, e tc . Provision shall be made fbr. trapping and disposing of flu id s lo s t by leakage or s p ills from the tra n sfe r system and from the storage containers. Drums to be re tire d from use shall be cleaned before crushing, delivery to scrap dealers, or other dlposal. Contaminated cleaning flu id s and m aterials shall be disposed of as indicated below. 3. Handling during manufacturing operations: I t 1s generally accepted th a exposure to 'c a p a c ito r PCB is not hazardous, provided simple precautions are taken. (a). Vapors. Maximum atmospheric concentration lim it (8 hours) recownended: one milligram of capacitor PCB per cubic meter o f a ir . Breathing vapor or fume from heated PCB should be avoided. Provision of adequate v en tilatio n and regulation o f manufacturing operations to avoid open exposure of hot PCB (j5.*C, or higher) shall be made. The gases produced when askarel 1s decomposed by very high temperatures (such as th a t o f an e le c tric arc) 1n the presence o f a ir or organic Insulating m aterials contains a high percentage o f hydrogen chloride, and small percentages o f carbon dioxide, carbon monoxide, and oxygen. Minute concentrations of th is combination o f gases are very unpleasai and i r r i ta t in g , thus giving ample warning of th e ir presence. When necessary, under emergency conditions, to en ter a space containing a high concentration of PCB vapor or decomposition products, a hose mask with blower, or breathing equip ment with a self-contained a ir supply should be used. [(Gas mask,: a ir H- 906220 GBRN003U73 3 resp irato r, o r hose mask without blower nay be used i f there is no danger o f oxygen deficiency, (considered to be a breathing atmosphere o f a t le a s t 192 oxygen and not more than 25 PCB)]. I f the odor o f PCB 1s detected by the person wearing protective equipment, he should Immediately go Into fresh' a ir . All gas masks, resp irato rs and replacement parts sh all hive Bureau of Hines approval, and be maintained on a regular schedule In accordance with the manufacturers re commendation. (b). Fluid. Unlike insulating o i l , there is v irtu a lly no fire hazard in handling PCB. A lim ited solvent action (sim ilar to th a t for paint thinner) on the fats and o ils o f the skin with prolonged contact may lead to drying and chapping of the skin. As with Insulating o i l , some people are a lle rg ic to PCB and continued exposure may re su lt 1n skin ir r i ta t io n . Both the liq u id and vapor are moderately ir r ita tin g to eye tis s u e s . Operating procedures should avoid contact with hot flu id s (about 55C). Use of eye protection 1s recoirmended. The use of gloves 1s not recommended. Contaminated clothing must be changed and laundered. Use o f enclosed tra n sfe r and handling equipment, processing equipment and the use o f mechanical washers CD g rroo reduces direct contact. Medicinal washes or detergents followed by an application of cold cream w ill eliminate any ir r ita tio n resu ltin g from askarel coming Into contact with an open cut or abrasion. Eye exposure to liq u id PCB should be Irrig a te d immediate with large q u an tities of running water from an approved eye wash source for f lf te i minutes and then be examined by a physician. Persons developing a skin I rr ita tio r or respiratory tr a c t ir r ita tio n apparently due to contact with PCB should be place under the supervision of a physician. (A drop of casto r o il has b>en found to neutralize any ir r ita tio n caused by contact of PCD with the eyes.) eBRN0 0 3H7 4 Ingestion or swallowing o f PCB's 1s not generally regarded as a problem of the industry,. PCB's are regarded as being moderately to x ic i f taken in tern al!: Swallowing several ounces could cause ir r ita tio n o f the*digestive tr a c t and in ternal reactio n s, and should be referred to a physician. _____ 4. Manufacturing control of lo sse s; Manufacturing equipment and operating procedures must safeguard against excessive loss of PCB to the environment througt close control and disposal procedures. Enclosed systems o f sealed piping, properly gasketed jo in ts , valves, con ta in e rs , and processing chambers are to be used fo r any portion of the operation where PCB temperatures may exceedS > C , Enclosure sh all preferably extend to all other portions of the system insofar as practicable. Drains"shall be plugged and curbs in sta lle d around a ll "open" portions of the PCB processing area, to assure against inadvertent loss to sewer systems by sp illa g e , leakage, or other uncontrolled lo ss. V entilation of the area and exhaust of pump and systems gases shall be directed through f i l t e r entrapment capable of restrain in g vapor losses to the atmosphere o f . _ m g /lite r, peak and kg per day. S p ills of PCB shall be removed promptly by use o f absorptive m aterial, pre ferably sawdust, or trapped and removed by pumping, o r by other su itab le means. Waste fluids containing PCB and not su ita b le fo r reconditioning or reuse shall be collected (by means o f tra p s , drip pans, tr a y s , e tc .) from the various parts of the manufacturing and processing area (including washers or other clean ing devices). Wiper rags, clothing and other extraneous m aterials saturated with PCB's shall be collected within the curbed area. 906222 BBRN003M75 s 5 5. Disposal of PCB w astes: Methods fo r disposal of liq u ids and saturated soltds generated by the manufacturing operation shall be 1n accordance with those outlined 1n subsquent portions o f th is standard and sh all Include (but not be lim ited to ) the following: A) Liquid PCB contaminated by a lip h a tic m aterials and other sub- stances such as to make i t unsuitable fo r reclaiming as a d ie le c tric flu id . Liquid PCB from solvent operations or w ater/detergent type washers. Saturated earth or other absorbent media from f ilte r in g operations. Saturated sawdust o r other absorptive m aterial from s p ills . E) Saturated f i l t e r s from vapor control devices and other f i l t e r s . Fj Saturated wastes (paper, rags, e tc .) ^ G) Saturated, spent gasket m aterials, v'' H) PCB contaminated vacuum pump o ils . I) PCB contaminated steam j e t vacuum pump condensates. 6. Miscellaneous Procedures: A) S p ills by leakage from sealed, finished capacitors should be clean ed up promptly by use of absorbent sawdust, which should then be moved to con tain ers for th a t purpose within the curbed or drained area, and la te r disposed of properly. B) PCB wastes should never be disposed o f, deliberately, down efflu en t drains or sewers. The utmost care must be excerised to prevent accidental loss by these means. C) Capacitors fa ilin g t e s t or otherwise designated fo r disposal must be controlled and handled 1n accordance with the in te n t o f the procedures above, fin a lly being disposed of by one o f the means outlined below. 7.
