SECTION IV, FIRE AND EXPLOSION DATA LOWER UPPER Flash Point and Method Autoignition Temp. fFlammabllity Limits In Air None to boiling point Extinguishing Media: Use media appropriate to the surrounding fire conditions. This material has very low combustibility, but it can undergo thermal-oxidative degradation in a fire situation. Firefighters should use ful^p^otective clothing and self-contained breathing equipment when fighting fire where/ny) PCB's are Involved. SECTION V. REACTIVITY DATA AROCLOR 1254 and other PCB's are nearly inert materials with very high chemical 6tabilitJy the higher chlorine levels usually give the greater stability. At about 300 to 600 C some PCB*6 can oxidize to produce chlorinated dibenzofurans which are much greater in toxicity than the PCB's. For complete incineration of PCB's a 2-second dwell time above 2000 F (1090 C) with 3% excess oxygen in the stack is suitable (see Sect. VII). jAROCLOR 1254 shows very little degradation after 3 weeks exposure to direct sunlight. PCB's are strongly absorbed on particulates or sediments in aquatic systems (streams, lake6, ocean, etc.). Mixed in activated sludge, biodegradation occurs slowly, but only very slowly or almost 1 not at all with compounds above CI4. GENERAL^ ELECTRIC Copyriflhli''--1980 By Ganaral daclrlc Company 0509553 TI TOWOLDMONOQ58930 u No. 1200 SECTION Vt, HEALTH HAZARD INFORMATION TLV (See Sect. II) PCBs show high levels of bioaccumulation in^atty' tissue and very slow' me'taboiiso, es pecially for CI5 compounds and above. They have become widely dispersed in world-wide] environment and In the food chain (much like DDT) since their introduction in 1929. , Effective control of PCB discharge into the environment began after 1970. IAR0CL0R 1254 has a low vapor pressure, but it can be Irritating to the eyes, nose, and throat if misted or heated to produce vapors. Excessive acute and chronic exposures mav cause liver damage. Chronic exposure to or TtTrgC^TT0TrT5T^ClTTr^eSTfbcially when*'"' theYMlIy' oxidized) can result in chloracne after 1-6 months.

"bkln Contact: Clean exposed skin with waterless cleaner, wipe with a disposable towel! then Wash with soap and water. Promply remove contaminated clothing. (Control separate disposal of PCB-contaminatea materials.) Eye Contact: Flush promptly & thoroughly with lots of running water for 15 minutes. Inhalation:' Remove to fresh air. Get tneaical help if symptoms continue. Ingestion: Get medical help. NIOSH has recommended that vomiting be induced. GeT medical help In all cases of severe exposure, repeated exposures, or persistent symptoms. SECTION VII, SPILL, LEAK, AND DISPOSAL PROCEDURES NoTify safety personnel oT all PCB spills"or leaks. Promptly contain spilled materiaiT "Prevent its release into the environment! Restrict PCB spill area to trained clean-up| personnel; use proper protective gear: follow an established emergency plan. Stop leakage if possible. Pick up spill. Absorb small spills and residues using a powdered, dry clay. Place leaking containers, picked-up PCBs, and PCB-contaminated materials ana refuse into approved, properly labeled, closed containers for storage under controlled, EPA regulated conditions prior to disposal. EPA allows approved storage to 1/1/84.(See Sect.IX.) Storage: 40CFR761.42; Annual report: 40CFR761.45 DISPOSAL: Destroy PCB-containing material by burning in an EPA approved facility. Liquip ~~5D-5Q0 ppm PCB material can be burned as above or landfilled iJrnot l'gnitable. Non flowing, PCB-contaminated debris can be disposed of in an EPA-approved landfill. (See 40CFR 761; Federal Register. Vol. 44, 31551-4, 66989; Vol.45. 20473.) SECTION VIII, SPECIAL PROTECTION INFORMATION Provide highly effective local exhaust ventilation (trap for exhaust vapors) especially j if this material i6 heated or misted. Unless authorized by EPA an isolated system must be used for PCBs. For nonroutine and emergency conditions of exposure use an approved canister respirator I I or self-contained breathing equipment. If Prevent skin contact for those who work with PCBs. Use neoprene or polyethylene gloves |' and apron, safety glasses and/or face shield, and other protective clothing as deter mined by use conditions. An eyewash station and washing facilities should be avail able to the work area. Provide for special handling and disposal of PCB-contaminated materials, including paper] towels and clothing (see Sect. VII). Provide locker and shower facilities. Workers I must be trained for PCB work, and they must follow good hygienic practice. Provide pre-placement medical exams for workers with emphasis on liver function, skin condition, and reproductive history. Provide annual medical exams for exposed workers! e SECTION IX, SPECIAL PRECAUTIONS AND COMMENTS PCB materials in containers and in equipment must have proper labeling including the date of storage. Short term (up to 30 days) storage of non-leaking PCBs can be done Long term storage requires an EPA approved facility, including such criteria as roof and walls to shield from rain, impervious base and diking which will contain 25% of stored volume or twice the volume of the largest container, no drains or openings to allow flow loss, and the base must be located above the 100-year flood water elevatiorj.
