As a general rule-of-thumb, degradation begins to occur after about one hour at 177 C (350 F), about 10 minutes at 204 C (400 F) and within five minutes at 232C (450 F). In case of power loss or other mishap, shut off the machine and dismantle the die assembly as soon as possible before degradation or decom position begins. If decomposition begins (with gassing and "popping" sounds) before the die can be disassembled, dangerously high pressure may occur in the die system. In this event, shut off the machine, clear the area of personnel and wait until decomposition stops.

Vinyl chloride and polyvinyl chloride (PVC) are not the same material. Vinyl chloride is a flam mable gas that is strictly regulated by DOT, EPA and OSHA. Through a chemical reaction, this gas -- known as a monomer -- is converted to a nonhazardous white granular powder called polyvinyl chloride resin, PVC or simply, vinyl. It is this vinyl resin that is then combined with functional additives to make Geon vinyl compound. Vinyl resin is not a cancer suspect agent. Moreover, the reaction is not reversible. That is, thermal pro cessing or decomposition will not cause polyvinyl chloride to revert back to vinyl chloride monomer. Employee exposure to vinyl chloride monomer (CAS Registry Number: 75-01-4), a carcinogen, is regulated by OSHA (29 CFR 1910.1017). The current regulation requires that no employee may be exposed to VCM concentrations greater than 1.0 ppm (parts per million by volume) averaged over any eight-hour period or 5.0 ppm averaged over any period not exceeding 15 minutes. The action level is 0.5 ppm averaged over any eighthour workday. The regulation applies to the manufacture, packaging, repackaging, storage, handling or use of vinyl chloride or polyvinyl chloride, but does not apply to the handling or use of fabricated products made of polyvinyl chloride. Purchasers of vinyl compound for processing purposes must comply with the permissible exposure limits set by OSHA. Moreover, the regulation requires a program of initial monitoring in each facility to determine if there is any employee exposure in excess of the action level without the use of respirators. If monitoring does not find VCM above 0.5 ppm, no further action is necessary. Refer to OSHA regulations (including 29 CFR 1910.1017) for complete details. SPECIAL NOTE: Vinyl Chloride Warning Labels on Compound Containers Monitoring of vinyl processing and fabricating plants and modeling studies show that the action level (0.5 ppm) cannot be exceeded when residual VCM is at or below 8.5 ppm in Geon' vinyl compound. Shipping containers for these compounds are not labeled by BFGoodrich o co o BFG01468 unless a customer specifies otherwise. Geon' vinyl compound will be labeled if residual monomer exceeds 8.5 ppm. The OSHA regula tion requires that the label say "Polyvinyl chloride contains vinyl chloride. Vinyl chloride is a cancer suspect agent." The vinyl in Geon- vinyl is not a cancer suspect agent. It is the trace amount of unreacted vinyl chloride monomer that must be controlled, not the vinyl resin itself. Although some containers may be labeled, this does not necessarily mean that employee expo sure to VCM will exceed permissible exposure limits. Using "worst case" conditions of thermal processing, our studies show that more than 30 ppm of unreacted monomer in vinyl resin is needed to cause 0.5 ppm to be present in the atmosphere of a hot. poorly ventilated workplace. For further information, please read BFGoodrich Technical Service Bulletin No. 12, "Vinyl Studies." Good ventilation in those areas where VCM might concentrate -- such as where con tainers are stored and first opened, where materials are mixed and where compound is melted -- will further ensure a work environment virtually free of VCM. APPENDIX 2 HAZARD COMMUNICATION The OSHA hazard communication standard requires that manufacturers of products state in the MSDS whether or not the material is listed as a carcinogen. The lists to be consulted include OSHA Health Standards, The International Agen cy for Research on Cancer (IARC) and the National Institute for Occupational Safety and Health's Registry of Toxic Effects of Chemical Substances (RTECS). NIOSH in the 1983 RTECS listed Polyvinyl Chloride (PVC) as a carcinogen. NIOSH mis interpreted the IARC monograph 19.377.76 (Summary of Data Reported and Evaluation). The monograph states that "studies (about).. the possibility of cancer in workers involved in the fabrication of plastics, including polyvinyl chlor ide, are insufficient to evaluate carcinogenicity." IARC monograph 19.419.79 correctly identified vinyl chloride monomer as a carcinogen. NIOSH's inexplicable expansion to include all the polymers listed (including Tygon which is used in medical tubing) was in error. The Vinyl Institute, a trade organization represen ting the PVC industries in June, 1987 managed to get the RTECS review board to correct the misinterpretation of the IARC monographs. Polyvinyl chloride is now listed as presenting inadequate evidence of being a human or animal carcinogen. APPENDIX 3 r" UNCTIONAL ADDITIVES USED IN PVC COMPOUND Additives chosen for a specific compound will vary according to processing and final product requirements. The followng list does not repre sent all possible additives but it does represent typical ingredients which may be used in vinyl compounds. Stabilizer inhibits thermal degradation of the compound during processing and throughout the service life of the product. Stabilizers may be grouped into four classes: organometallic tins, lead salts, mixed metal salts and specialpurpose stabilizers. The most common organo metallic tin stabilizers are tin mercaptides, mainly methyl tin and butyl tin. Some stabilizers, including di-n-octyl and dimethyl tin mercaptide, are FDA acceptable for food contact applications. Geon-5 vinyl compound containing organic tins are labelled. Lead salts, like dibasic lead phosphite, are mainly organic lead compounds and include sulfates, silicates, phosphates, stearates, phthalates and maleates. Powdered lead compounds are labelled. Lead compounds will not be emitted into the workplace during normal thermal processing operations. Mixed metal salts include calcium-zinc and barium-cadmium systems. Special-purpose stabilizers include flame retardants such as antimony derivatives and ultraviolet light absorbers. Stabilizer will typically be present in amounts up to 5% by weight. Processing aids -- The most common pro cessing aids used with vinyl compound are acrylics or styrene-acrylonitrile copolymers present at levels up to 5.0% by weight. Impact modifiers commonly used with vinyl include acrylates, chlorinated polyethylene, methacrylate-butadiene-styrene (MBS), acrylonitrile-butadiene-styrene (ABS) and rub ber. Although not present in all compounds, when used, impact modifier may range up to 20% by weight. Fillers -- Most common are metal carbonates, mainly calcium carbonate, which is usually in the form of ground limestone and coated with stearic acid. Other fillers may be silicates, gypsum, clay, alum and barytes. Plasticizer -- Many kinds of plasticizer are available such as dioctyl, dihexyl and dibutyl phthlates, phosphate esters such as isodecyl diphenyl phosphate, aliphatic alcohol esters such as dioctyl adipate, polymeric plasticizer such as polyesters of adipic acid and monomeric esters such as trimellitate. Dioctyl phthlate is FDA acceptable for food contact applications. When used in flexible vinyl compound, plasticizer concentrations will generally range between 20-50%, by weight. Lubricants -- include paraffin waxes, mineral oils, polyethylene, salts of fatty acids and fatty acids, esters and amides. Lubricants would be present up to approximately 5%. Pigment -- Pigments may be present up to 5% to achieve opacity and color. o 3 BFG01469 UlFGoodrich Geon Vinyl Division 6100 Oak Tree Boulevard Cleveland, Ohio 44131 216-477-6000 Domestic Sales Offices GREAT LAKES MIDDLEBURG HTS, OH 44130 7550 Lucerne Drive, Suite 115 216-234-1330 NORTHEASTERN MIDDLEBURG HTS, OH 44130 7550 Lucerne Drive, Suite 115 216-234-1330 SOUTHEASTERN ATLANTA, GA 30339 2840 Mount Wilkenson Pkwy.
