CfenbUBjgloa->Prp4t/v{;-V _i;'- - - When"forced to burr.,''about 97% of the combustion gases from vinyl resin will be a combination of hydrogen chloride, carbon monoxide and carbon dioxide. Other gases will include small amounts of benzene and aromatic and aliphatic hydrocarbons. The combustion products of vinyl resin, like those from other natural and synthetic materials, must be considered toxic. Like wood, paper and cotton, the major hazard is carbon monoxide. Carbon monoxide is an asphyxiant while hydrogen chloride is an irritant. When vinyl is burned, it will have a detectable, pungent odor. BFG50399 tcor. C'. CO -4- Uausual Fire and Explosion Hazards Hydrogen chloride has a corrosive effect on many metals. Affected equipment surfaces and unprotected structural elements of buildings should be washed to remove corrosive deposits as soon as possible after depositions have occurred. e Vinyl resin is not considered to be a dust explosion risk.. The potential hazard has been evaluated using the Hartmann Vertical Tube Apparatus. Data has also been reported by the National Fire Protection Association (NFPA). (1) In the Hartmann apparatus, vinyl resin representing fine particle size (2 Microns), medium particle size (75 Microns) and large particle size <130 Microns) does not ignite or explode in concentrations up to 2.0 gm/liter. (2) The NFPA shows "fine" particle size vinyl resin to have a low order of risk.* Explosibility index: < < 0.1 (Weak) Ignition sensitivity: < < 0.1 (Weak) Explosion severity: < 0.1 (Weak) Ignition temp., dust cloud: 660C (1220F) ^Source: NFPA 654-1975, "Prevention of Dust Explosions in the Plastics Industry." < < 0.1 means that ignition of the dust cloud is not obtained by a spark or flame source. As a precaution, it is prudent to employ standard safety measures used in handling finely divided organic powders. SECTION V - HEALTH HAZARD DATA Threshold Limit Value None established Effects of Overexposure There are no significant health hazards from vinyl resin at ambient temperature (see Dust Exposure). e No adverse health effects are expected from processing vinyl resin when potential exposures are minimized by good industrial hygiene practice and adequate ventilation. Nevertheless, at processing temperatures, the sum total of all ingredients in a vinyl-based compound (e.g., vinyl resin, stabilizer, lubricant, modifier, etc.) may emit fumes and vapors that are irritating to the respiratory tract, eyes or skin of some sensitive people. This depends upon processing technique and temperature, volume processed and most importantly, the effectiveness of exhaust ventilation provided to the process area. BFG50400 f. W O 2626300S -5- Inhalation of decomposition or combustion products, especially hydrogen chloride, will cause irritation of the respiratory tract, eyes and skin. Depending on the severity of exposure, physiological response will be coughing, pain and inflammation. Individuals with bronchial asthma and other types of chronic obstructive respiratory diseases may develop bronchspasm if exposure is prolonged. SPECIAL MOTE: Hydrogen chloride is detectable by its sharp, pungent odor in concentrations as low as 1-5 ppm. Low concentrations (below 50 ppm) are not harmful in short-term exposures, but do provide excellent warning properties by causing coughing or irritation. Because the protective response is so strong, humans rarely submit to damaging concentrations -- instead, there is an unmistakable urge to leave the area. Repeated or prolonged exposure to high concentrations can cause eye and respiratory damage. In studies sponsored by the Federal Aviation Administration, no incapacitation, no impairment to escape and no significant post-exposure effects occurred in baboons exposed to hydrogen chloride up to 11,400 ppm (1.14%). OSHA has established a ceiling limit of 5 ppm for workplace exposure to hydrogen chloride. Emergency and First Aid Procedure If irritation persists from exposure to processing vapors or decomposition products, remove the affected individual from the area. Call a physician. protection before allowing reentry. Provide Toxicology Overview Geon vinyl resins have been evaluated by studies involving the intracutaneous (skin) and intramuscular injection in rabbits, by studies involving dietary administration (i.e., ingestion) to rats for nearly the lifetime of the animals, and by numerous human patch tests using panels of 50 or more people. Mo significant reactions, skin irritation, sensitization, or other deleterious effects have been observed in these studies. Dust Exposure Vinyl resin has little effect on the lungs and is not known to cause any disease when dust exposure is minimized. While there is no evidence of a substantial risk to health, a British study found a small decrease in breathing capacity for workers who smoked and were exposed to vinyl resin dust. This decrease was about one-seventh of that caused by normal aging and about equal to that expected with a one-p&ck-a-day cigarette smoker. There was no significant decrease in breathing capacity from inhalation of vinyl resin dust by non-smokers. The American Conference of Governmental Industrial Hygienists* Threshold Limit Value (1984) for nuisance dust is 10 mg/ra3 for total dust and 5 mg/m3 for respirable dust. Respirable dust are those particles in a size range below 10 microns. Typical particle size for suspension and mass vinyl resin is 70-150 microns; blending resin is 25-130 microns. Dispersion resin has an average particle size below 5 microns. Routine inhalation of dust of any kind should be avoided. Exercise care when dumping bags, sweeping, mixing or doing other tasks which can create dust. Where large amounts of any dust may occur, wear a respirator approved by NIOSH/MSHA to protect against nuisance dust.

Incompatibility (materials to avoid) Avoid contact with acetal or acetal copolymers and with amine containing materials during processing. At processing conditions these materials are mutually destructive and involve rapid degradation. Thoroughly purge and mechanically clean processing equipment to avoid even trace quantities of these materials from coming in contact with each other. Prevent cross contamination of feedstocks. SECTION VII - SPILL OR LEAK PROCEDURE Steps to be taken in case material is released or spilled Vacuum or sweep into a closed container for reuse or disposal. Waste Disposal Method Dispose of waste in a licensed landfill or by incineration in accordance with federal, state and local regulations. For waste disposal purposes, Ceon vinyl resins are not defined or designated as hazardous by current provisions of the Federal Resource Conservation and Recovery Act (RCKA -- 40CFR261). If incinerated, be aware that hydrogen chloride is generated. SECTION VIII - SPECIAL PROTECTION INFORMATION BFG50402 Ventilation Provide effective exhaust ventilation to draw dust and/or fumes away from workers to prevent routine inhalation. Compounding, hot melt processing (extruding, molding, etc.), cutting or sawing, machining, regrinding, thermoforming, heat welding and other processing or post-processing operations involving heat sufficient to result in polymer breakdown should be examined to ensure adequate ventilation. Ventilation guidelines and techniques may be found in the following publications: - NIOSH Recommended Industrial Ventilation Guidelines; GPO #017-033-00136-7. Available from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402 ($9.00 as of December, 1984). - Industrial Ventilation, 18th Edition; Available from the American Conference of Governmental Industrial Hygienists, 6500 Glenway Ave., Bldg. D-5, Cincinnati, Ohio 45211 ($15.00 as of December, 1984). Respiratory Protection Not normally required. Abnormal conditions such as equipment malfunction, use of improper equipment or procedures, or hangup or stagnation of vinyl-based compound during processing may cause decomposition. Employees involved in removing decomposing material should be provided with suitable air-supplied respirators, euch as NIQSH/HSHA.-approved positive pressure, self-contained breathing apparatus. 7- 2263008 Protective Equipment Not normally required. Wear protective gloves when handling hot material during processing. Safety glasses are recommended for all industrial workplaces. SECTION IX - SPECIAL PRECAUTIONS (For vinyl resin and vinyl-based compound) Normal Melt Processing. Virtually all thermoplastic materials will emit fumes and/or vapors when heated to processing temperatures. The concentration and composition of these vapors will depend upon variables such as specific compound formulation and processing method and temperature. Always use vinyl resin under well-ventilated conditions and avoid continued or prolonged breathing of process vapors. For personal hygiene, wash thoroughly after handling resin, especially before eating, smoking or using toilet facilities. Do not store or consume food in processing areas. Do not use processing equipment to heat food. Cleanup following normal melt processing should be performed under well-ventilated conditions. Compound based upon vinyl resin may be held at process temperatures for a short time without significant thermal degradation. However, it should be recognized that exposure to either elevated temperature or excessive heat history (time) will result in decomposition.* Equipment should not be shut down for extended time periods with vinyl compound in it, or decomposition and possible corrosion of unprotected metal may result. If dies and screws are not to be cleaned manually, then compound should be purged from processing equipment prior to shutdown using special vinyl purge compound or a compatible thermoplastic such as general purpose A6S (do not use flame-retarded or halogen-containing grades for this purpose). *Time and temperature required to initiate degradation will vary depending upon processing technique, degree of compound stabilization and other factors. As a general rule-of-thumb, degradation begins to occur after about one hour at 177C (350F>, about ten minutes at 204C (400F) and within five minutes at 232C (450F). In case of power loss or other mishap, shut off the machine and dismantle the die assembly as soon as possible before degradation or decomposition 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. Thoroughly ventilate the area. Remove and disassemble the die system. These are guidelines only. Refer to technical service reports and equipment manufacturer's recommendations for specific procedures. Regrinding scrap normally generates substantial heat. Cool regrind before placing it in containers. The excellent insulating quality of vinyl will prevent heat in the center of a container from escaping, potentially resulting in slow thermal decomposition of the material. This may not only render the product unsatisfactory for further processing but also result in fumes and vapors being released into the workplace atmosphere. Remove vinyl resin from walkways and floors to prevent slippery footing. Spcinklered warehouse areas are recommended. Although vinyl resin by itself will not support combustion, materials such as wooden pallets, cardboard boxes and other combustibles can provide sufficient fuel to force vinyl to burn. BFG50403 26263009 8- - Compounding vinyl resin. Many of the common compounding ingredients which are mixed with vinyl resin may require special handling, especially respiratory protection. It is the user's responsibility to obtain and follow the recommended precautions of the individual additive supplier. SPECIAL MOTE: Vinyl compound at or above normal processing temperature must never be allowed to accumulate in thick masses, or it will begin to thermally decompose and to swell due to internal gassing. Gassing may cause a thick mass to explode if its outside surface is hardened. Molten waste should be collected as strands or flattened to 2-inches or less, and quenched in a drum of cold water provided for this purpose. Decomposing material should be removed to a well-ventilated area, preferably outdoors. SECTION X - TRANSPORTATION For domestic transportation purposes, vinyl resins are not classified as hazardous by the U.S. Department of Transportation under Title 49 of the Code of Federal Regulations, 1983 Edition.

B?G50404 9- - *?t>2630io APPENDIX 1 - VINYL CHLORIDE MONOMER (VCM) Employee exposure to vinyl chloride monomer (CAS Registry Number: 75-01-4), a carcinogen, is regulated by OSHA (29CFR1910.1017). 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 eight-hour work day. 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. Typically, purchasers of vinyl resin to be compounded or further processed 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 29CFR1910.1017) for complete details. SPECIAL NOTE: Vinvl Chloride Warning Labels on Resin 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 S.5 ppm in Geon vinyl resin. Shipping containers for these resins are not labeled by BFGoodrich unless a customer specifies otherwise. Vinyl prime, off-grade or scrap resin is labeled if residual monomer exceeds 8.5 ppm. The OSHA regulation requires that the label say "Polyvinyl chloride contains vinyl chloride. Vinyl chloride is a cancer suspect agent." Polyvinyl chloride resin 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 exposure 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 containers are stored and first opened, where materials are mixed and where resin is melted -- will further ensure a work environment virtually free of VCM.
