Vinyl resin by itself will not support combustion because it requires a higher concentration of oxygen for burning than is present in the earth* s atmosphere. Vinyl resin can be forced to bum by continuous application of intense heat. Like all combustible material, protect from open flame and maintain proper clearance when using portable heat devices, etc. Store flammable liquids away from vinyl resin. 200e292 wp6/0507j BFG50214 -3- Flash-Ignition Temperature: The lowest initial temperature of air passing around the specimen at which sufficient combustible gas is evolved to be ignited by a small external pilot flame. Self-Ignition Temperature: The lowest initial temperature of air passing around the specimen at which, in the absence of an ignition source, ignition occurs of itself, as indicated by an explosion, flame or sustained glow. Special Firefighting Procedure Wear positive pressure self-contained breathing apparatus CSCBA). Personnel not having suitable respiratory protection must leave the area to prevent significant exposure to toxic combustion gases from any source. In enclosed or poorly ventilated areas, wear SCBA during cleanup immediately after a fire as well as during the firefighting operations. Extinguishing Media Water is most effective. ABC dry chemical, AFFF, and protein type air foams are also effective. Geon Off-Grade Vinyl resins are ''ordinary combustibles'* (WFPA defined Class A). Carbon dioxide is not generally recommended for use on Class A fires as a lack of cooling capacity may result in reignition. Combustion Products When forced to bum, about 97% of the combustion gases from vinyl resin will be a combination of carbon monoxide, and carbon dioxide and hydrogen chloride. 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 resin is burned, it will have a detectable, pungent odor. Unusual 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 with water based detergent solution to remove corrosive deposits as soon as possible after depositions have occurred.* Off-Grade 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 gra/liter. 26230003 wp6/0507j BFG50215 -4- (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 BPG Recommended 5mg/H3 Respirable Carcinogenic Status See Appendix I Primary Routes of Entry Eye, skin, inhalation. Effects of overexposure: Vinyl chloride monomer - Processing of Geon Off-Grade resin containing high residual vinyl chloride monomer with inadequate ventilation may result in employee workplace exposure to levels of vinyl chloride in excess of the OSHA permissible limits. 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 an 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. 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 initiai 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. wp6/0507j 26230004 BFG50216 -5- For further information, please read BFGoodrich Technical Service Bulletin Mo. 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. Process Upset Conditions: Mo adverse health effects are expected from processing Geon Off-Grade 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 resin-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. 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. Medical Conditions Aggravated by Overexposure: Individuals with bronchial asthma and other types of chronic obstructive respiratory diseases may develop bronchiospasm 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%) for fifteen minutes. 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. Provide protection before allowing reentry. Dust Exposure: Vinyl resin has little effect on the lungs and is not known to cause any disease when dust exposure is minimized. wp6/0507j BFG50217 26230005 -6- 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-pack-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/m3 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 vinyl resin is 1.2 150 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 HIOSK/MSHA to protect against nuisance dust. SECTION VI - REACTIVITY DATA Stability Stable Hazardous Polymerization Will not occur Hazardous Decomposition Products Carbon monoxide, carbon dioxide, hydrogen chloride, and small amounts of benzene and aromatic and aliphatic hydrocarbons. 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. Use care to avoid dust generation. Store in a safe location to await disposal. Do not flush chemical into public sewer or water system. Wear protective clothing, monogoggles and dust respirator if cleanup actions will result in the creation of airborne dust. Waste Disposal Method Landfill or incineration in accordance with federal, state and local regulations. This product is not defined or designated as hazardous by current provisions of the Federal Resource Conservation and Recovery Act (RCRA). 40 CFR 261. If incinerated, be aware that hydrogen chloride is generated. wp6/0507j 16230006 BFG50218 -7- SECTION VIII - SPECIAL PROTECTION INFORMATION 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. Some degassing of Vinyl Chloride will occur during shipment and storage. Precautions should be taken during container opening and prior to trailer entry. Containers or trailers shotild be opened under ventilated conditions and allowed to ventilate to the atmosphere for at least 30 minutes or time sufficient for the accumulation of Vinyl Chloride monomer to dissapate prior to handling or entry. Store in ventilated area to prevent build-up of Vinyl Chloride monomer. Respiratory Protection If monitoring shows employee exposures above OSHA PEL, utilize appropriate' respiratory protection until engineering controls have been installed to lower ambient VCM levels to below the OSHA PEL. See OSHA Vinyl Chloride Standard 29 CFR 1910.1017 for respirator selection guide. If excessive dust conditions are encountered wear a respirator approved by NIOSH/MSHA to protect against nuiscance dust. Abnormal conditions such as equipment malfunction, use of improper equipment or procedures, or hangup or stagnation of vinyl resin-based compound during processing may cause decomposition. Employees involved in removing decomposing material should be provided with suitable air-supplied respirators, such as MIOSH/MSHA-approved positive pressure, self-contained breathing apparatus. -Wear protective gloves when handling hot material during processing. -Wear monogoggles suitable for keeping dust out of the eyes. v -Avoid breathing dust. -Do not get in eyes, on skin or on clothing. SECTION IX - SPECIAL PRECAUTIONS 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. Vinyl chloride monomer may be present due to high residual concentration in Geon# off-grade vinyl resin. 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. wp6/0507j BFG50219 26230007 -8- Cleanup following normal melt processing should be performed under well-ventilated conditions. Vinyl chloride monomer may be given off due to high residual monomer in off-grade vinyl resin. If airborne concentrations of vinyl chloride exceed the PEL, airline respirators need to be worn. 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 ABS (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 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. Before entry into unkown concentrations of gases, don self-contained breathing apparatus. 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. wp6/0507j 26230008 BFG50220 -9- Sprinklered 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 resin to burn. Compounding vinyl resin. Many of the common compounding ingredients which are mixed with vinyl resin may require special handling, especially respiratory protection. It is your 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.

Vinyl Chloride is a cancer suspect agent. Breathing of excessive amounts of dust over a long period of time may cause a slight reduction in breathing capacity. Off-gassing of Vinyl Chloride during storage or processing may result in airborne concentrations of Vinyl Chloride above the OSHA permissible limit. Exposure to Vinyl Chloride has been associated with cancer. Overheating or degradation may emit fumes containing hydorgen chloride (HC1), may cause eye, respiratory tract or skin irritation. Precautions: Store in well ventilated areas. Process to prevent release of dust. Process with adequate ventilation. In case of overheating or degradation, wear positive pressure, self-contained breathing apparatus (SCBA). In case of fire, extinguish with water. DISCLAIMER OF LIABILITY As the conditions or methods of use are beyond our control, we do not assume any responsibility and expressly disclaim any liability for any use of this material. Information contained herein is believed to be true and accurate, but all statements or suggestions are made without warranty, express or implied, regarding accuracy of the information, the hazards connected with the use of the material or the results to be obtained from the use thereof. Compliance with all applicable federal, state and local laws and regulations remains the responsibility of the user. APPENDIX I 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 Agency for Research on Cancer (IARC) and the National Institute for Occupational Safety and Health's Registry of Toxic Efffects of Chemical Substances (RTECS) NIOSH in RTECS has listed Polyvinyl Chloride (PVC) as a carcinogen. NIOSH has misinterpreted the IARC monograph 19.377.76 (Summary of Data Reported and Evaluation). The monograph states that "studies (about)... the possibility of cancer on workers involved in the fabrication of plastics, including Polyvinyl Chloride, are insufficient to evaluate carcinogenicity IARC monograph 19.419.79 correctly identifies Vinyl Chloride monomer as a carcinogen. NIOSH*s inexplicable expansion to include all the polymers listed (including Tygon which is used in medical tubing) is in error. The Vinyl Institute, a trade organization representing the PVC industries, is working with the RTECS review board to correct the misinterpretation of the IARC monographs. wp6/0507j 26230010 BFG50222
