Combustion Products
When forced to burn, the primary combustion gases from vinyl compound will be hydrogen chloride, carbon monoxide and carbon dioxide. Othergases will include small amounts of benzene and aromatic and aliphatic hydrocarbons. Plasticized compounds will also contribute aliphatic olefins.
The combustion productsofvinyl, 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.
Unusual Fire and Explosion Hazards Hydrogen chloride has a corrosive effect on many
metals. Affected equipment surfaces and unpro
tected structural elements of buildings should be washed to remove corrosive deposits as soon as possible after depositions have occurred.
Pellet compound does not represent any explosion risk because of its large particle size. Powder com pound may have dust explosion potential because of fine particle size fillers and additives or liquids added to vinyl resin.

* NFPA 654-1975, "Prevention of Dust Explosions in the Plastics Industry'
Because of the wide variety of possible ingredient combinations, operations using plasticized or unplasticized powder compound should be evalu ated on an individual basis. Implement precautions to control or eliminate likely sources of ignition, such as static build-up. Maintain good housekeep ing, notably, ventilation, to prevent accumulation of potentially explosive dust concentrations. Properly maintain and operate dust control devices.
No adverse health effects are expected from proces sing vinyl compound when potential exposures are minimized by good industrial hygiene practice and adequate ventilation. Nevertheless, individual addi tives and/or various combinations of additives may affect the overall toxicological properties. Detailed
stud ies have not been performed on each of the many possible additive combinations. At processing temperatures, additives 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 prod ucts, especially hydrogen chloride, will cause irrita tion 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 NOTE: Hydrogen chloride is detectable by its sharp, pungent odor in concentrations as low as 1-5 ppm. Lowconcentrations (below 50 ppm) are not harm ful 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 concentrationscan cause eye and respiratory damage. In studies sponsored by the Federal Aviation Administration, no incapacitation, no impairment to escape and no signif icant post-exposure effects occurred in baboons exposed to hydrogen chloride up to 11,400ppm (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. Provide protection before allowing reentry.
Dust Exposure Fine particle size additives in powder compound may result in airborne dust. Routine inhalation of dust of any kind should be avoided. Exercise care when dump ing 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.

SPECIAL PROTECTION INFORMATION
Ventilation Provide effective exhaust ventilation to draw dust and/ or fumes away from workers to prevent routine inhala tion. Compounding, hot melt processing (extruding, molding, etc.), cutting or sawing, machining, regrindIng, heat welding, thermoforming, and other proces sing 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 Superintendentof 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 Indus trial Hygienists, 6500 Glenway Avenue, Bldg. D-5, Cincinnati, Ohio45211 ($15.00 as of December 1984).
Respiratory Protection Not normally required. Abnormal conditions such as equipment malfunction or use of improper equipment or procedures, or hangup or stagnation of compound during processing may cause decomposition. Employ ees involved in removing decomposing material should be provided with suitable air-supplied respira tors, such as NIOSH/MSHA-approved positive pressure, self-contained breathing apparatus.
Protective Equipment Not normally required. Wear protective gloves when handling hot material during processing. Safety glasses are recommended for all industrial work places.
SECTION IX
SPECIAL PRECAUTIONS
Normal Melt Processing. Virtually all thermoplastic materialswill emit fumes and/orvapors when heated to processing temperatures. Theconcentration and com position of these vapors will depend upon variables such as the specific compound formulation and proc essing method and temperature. Always use vinyl compound under well-ventilated conditions and avoid continued or prolonged breathing of process vapors. For personal hygiene, wash thoroughly after proces sing compound, 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 underwell-ventilated conditions. Vinyl com pound may be held at process temperatures for a short time without significant thermal degradation. How ever, it should be recognized that exposureto either ele vated temperature or excessive heat history (time) will result in decomposition.* Equipment should not be shutdown forextended timeperiods with compound in it, or decomposition and possible corrosion of unpro tected 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 thermo plastic such as general purpose ABS (do not use flameretarded or halogen-containing grades for this purpose).
'The time and temperature required to initiatedegradation will vary depending upon processing technique, degreeofcompound stabili zation and other factors. As a general rule-of-thumb, degradation begins to occur after about one hour at 177C (350F), about 10 minutes at 204C (400F) and within five minutes at 232C (450F).

This hay not only render the product unsatisfactory for liifllior processing but also result in fumes and vapors oolug released into the workplace atmosphere.
Remove vinyl compound from walkways and floors to pmvnnt slippery footing. Always wear rubber gloves w* inn cleaning condensate from exhaust equipment or other surfaces.
Sprlnklered warehouse areas are recommended. Although most vinyl compound by itself will not sup port combustion, materials such as wooden pallets, Crtidlxjard boxes and other combustibles can provide sufficient fuel to cause vinyl to burn.

APPENDIX 1
VINYL CHLORIDE MONOMER (VCM)
Employee exposure to vinyl chloride monomer (CAS Registry Number: 75-014), 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 oyer any eight-hour period or 5.0 ppm averaged over any period not exceeding 15 min utes. 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 compound for processing purposes must comply with the permissi ble exposure limits set by OSHA. Moreover, the regula tion 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 respira tors. 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: 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 unless a customer specifies otherwise. Vinyl compound will be labeled if residual monomer exceeds 8.5 ppm. The OSHA regulation requires that the label says "Polyvinyl chloride contains vinyl chloride. Vinyl chloride is a cancer suspect agent."
Polyvinyl chloride is not a cancer suspect agent. It is the trace amount of unreacted vinyl chloride monomer that must be controlled, not the vinyl 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 areaswhere VCM might con centrate - such as where containers 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
FUNCTIONAL ADDITIVES USED IN
PVC COMPOUND
Additives chosen for a specific compound will vary according to processing and final product require ments. The following list does not represent all possi ble additives but it does represent typical ingredients which may be used in vinyl compounds.
Stabilizer inhibits thermal degradation of the com pound 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 special-purpose stabilizers. The most common organometallic 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. Lead salts, like dibasic lead phosphite, are mainly organic lead compounds and include sul fates, silicates, phosphates, stearates, phthalates and maleates. Mixed metal salts include calciumzinc and barium-cadmium systems. Special-purpose stabilizers include flame retardants such as anti mony derivatives and ultraviolet light absorbers. Sta bilizer will typically be present in amounts up to 5% by weight.
Processing aids. The most common processing aids used with vinyl compound are acrylics or styreneacrylonitrile copolymers present at levels up to 5.0% by weight.
Impact modifiers commonly used with vinyl include acrylates, chlorinated polyethylene, methacrylatebutadiene-styrene (MBS), acrylonitrile-butadienestyrene (ABS), and rubber. 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 unusally 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 plasticizers are available such as dioctyl, dihexyl and dibutyl phthlates, phos phate esters such as isodecyl diphenyl phosphate, aliphatic alcohol esters such asdioctyl adipate, poly meric plasticizer such as polyesters of adipic acid, and monomeric esters such as trimellitate. Dioctyl phthlate is FDA acceptable for food contact applica tions. When used in flexible vinyl compound, plastici zer concentration 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 A list of common pigments appears in Sec tion II. Pigments may be present up to 5% to achieve opacity and color. In weatherable compounds, titanium dioxide may be present at concentrations up to 10-15% to achieve acceptable ultraviolet light screening.
APPENDIX 3 HAZARDOUS SUBSTANCES
No polychlorinated biphenyls(PCB)orpolybrominated
biphenyls (PBB) and none of the following materials designated as toxic and hazardous by the U.S. Depart ment of Labor (OSHA) are used to manufacture Geon vinyl resin or compound nor are they anticipated by products in our production process. Some of these materials are ubiquitous and trace quantities may be found in the environmentoras impurities in ingredients used in compound.
