Issue Date: January, 1980 DlFGcodrieh to Bulletin G-62 Second Edition MATERIAL SAFETY DATA Geon Vinyl Resins, Compounds ABOUT THIS BULLETIN The data in this bulletin is applicable to all Geon" vinyl resins -- general purpose type, Super EP type, dispersion resins, blending resins, powder coating resins -- and to all grades of rigid, flexible and Geon- cellular vinyl compounds. This bulletin is not applicable to Geon' latexes nc to Geon* CPVC materials. The data in this bulletin is limited to the safe hand ling and use of the PVC polymer itself and to PVC based compounds we manufacture. It does not in clude information on the suitability of PVC for any particular application nor discuss any precautions that may be necessary during product use in sen/ice. The format used to report material safety data infor mation is essentially similar to the U.S. Department of Labor Form OSHA 20 modified to facilitate de scription of our materials. USER'S RESPONSIBILITIES A bulletin such as this cannot be expected to cover all possible individual situations. In addition, the conditions under which our products are processed and used are beyond our control. The products de scribed herein can be hazardous if not processed properly. As the user of Geon' vinyls has the respon sibility to provide a safe workplace, all aspects of an individual operation should be examined to deter mine if or where precautions, in addition to those de scribed herein, afe required. Any health hazard and safety information contained herein should be pass ed on to your customers or employees, as the case may be. BFGoodrich must rely on the user of Geon'v vinyls to utilize the information we have supplied to develop work practice guidelines and employee instructural programs for the individual operation. DISCLAIMER OF LIABILITY As the conditions or methods of use are beyond our control, we do not assume any responsibility and ex pressly disclaim any liability for any use of this material. Information contained herein is believed to be true and accurate but all statements or sugges tions are made without any warranty, express or im plied, regarding accuracy of the information, the hazards connected with the use of the material or the results to be obtained from the use thereof. GENERAL INFORMATION This bulletin has been prepared to provide guide lines and appropriate precautions to assist our cus tomers in the safe handling and use of Geon1 vinyl resins and compounds. BFGoodrich recommends that, before use, safety personnel and employees handling Geon- vinyls read and understand the in formation and precautions presented herein. During processing or post-processing operations in volving heat sufficient to cause mass melting, the sum total of the compounding ingredients present may emit vapors and odors irritating to the respira tory tract, eyes and skin. BFGoodrich recommends that Geon*' vinyls always be used under well-venti lated conditions to avoid significant employee ex posure. SECTION I Manufacturer's Name The BFGoodrich Company, Chemical Group Address 6100 Oak Tree Boulevard, Cleveland, OH 44131 Telephone Number (216) 524-0200 Trademark Geon Vinyls , 't Chemical Name Poly (vinyl chloride), PVC Formula (CH2 CHCL)n Chemical Family Vinyl Chloride Homopolymer (with the following exceptions): Geon41 135,130x24: Copolymer of vinyl chloride/vinyl acetate Geon4 130x17: Carboxy-modified vinyl chloride polymer V SECTION II HAZARDOUS INGREDIENTS PVC resins contain small but detectable amounts of re sidual vinyl chloride monomer (VCM), a cancer-suspect agent. Extensive product and process improvements have resulted in the reduction of residual vinyl chloride monomer to a very low level in prime grades of major Geon'4 vinyl resins (See Table 1 and read Section V). Other ingredients, such as stabilizers, lubricants, plas ticizers, and pigments are added with resin to manufac ture PVC compounds. The sum total of all ingredients will emit vapors during processing. All possible health effects of these vapors are not known and individual sensitivities will vary. Exposure may produce acute health effects in some sensitive individuals. The ef fects relate primarily to eye, nose, and throat irritation. Efficient ventilation should be provided (read Section VIII) to prevent significant employee exposure. BFGoodrich recommends that these materials be used under well-ventilated conditions to avoid breathing these vapors. VC5515 Solvents No organic solvents are used in the manufacture of Geon*9 vinyl resins. Organic solvents may be used in the manufacture of stabilizers and other ingredients, and therefore, be detectable in small amounts in PVC compound. Carcinogenic Chemicals See Table III. Heavy Metals A) Resin: No lead, mercury, other heavy metals or heavy metal compounds are used in the manufac ture of Geon *' vinyl resins. These materials are ubiq uitous and trace quantities may be found in the environment. B) Compound: Geon" vinyi compounds contain heavy metal stabilizers generally in amounts less than 5%. These may include organometallics such as tin, lead, cadmium, barium and zinc and metallic salts such as basic lead carbonate and basic lead sulfate. Plasticizer Geon" vinyl flexible (plasticized) compounds will con tain polymeric, monomeric or mixed ester plasticizer in amounts oenerally between 20%-50%. These materials are volatile when heated, and will contribute to the sum total of the vapors released during processing. Pigments Geon* vinyl compounds may contain commonly avail able pigments based on lead, iron oxide, carbon black, chromium, ultramarines, titanium dioxide, mercadmiums, phthalocyanines, molybdates, quinacridones and other organic or inorganic materials. In cube com pound. these pigments are typically bound-up in our manufacturing process and are not expected to create any hazard in handling or processing. In powder com pounds, because of potential dusty conditions, respiratory protection may be required. If conditions exist where dust is possible, the employee should be provided with a suitable NIOSH approved respiratory protection device. (See Section VIII. See Table III). 1 SECTION III i, PHYSICAL DATA Specific Gravity (H,0 = 1.0). Resin: L40. Compound: See Product Data Sheet.* S lubility In Water - Slight. Particle Size. Resin: See Table II Compound: Cubes measuring approximately 3/16-inch per side; or powder. Particle size of powder compound varies due to compounding ingredients. Appearance and Odor Resin: White powder, practically odorless or bland odor. C mp und: Pigmented or unpigmented cubical gran ules or powder, slight odor. SECTION IV FIRE AND EXPLOSION HAZARD DATA Extinguishing Media Water is most effective. ABC dry powder and protein type air foams are also effective. Geon15, vinyls would be considered "ordinary combustibles" (NFPA defined Class A). Carbon dioxide is not generally recommend ed for use on Class A fires as a lack of cooling capacity may result in reignition. Special Fire Fighting Procedure Self-contained breathing apparatus should be used for fires in which PVC becomes involved. Personnel not having suitable respiratory protection should leave the area to prevent significant exposure to toxic combus tion gases. Decomposition Products A) When forced to burn, PVC combustion products will mainly be carbon monoxide, carbon dioxide, hydro gen chloride and smoke: Other gases, including aromatics and aliphatics, are present in small amounts. Geon" 135 and 130x24 will also contribute minor amounts of acetic acid as gas and smoke. Inhalation of, or overexposure to, PVC combustion products and primarily hydrogen chloride will cause irritation of the respiratory tract, eyes and skin. De pending on the severity of exposure, physiological response to inhalation will be coughing, pain, in flammation, edema, and desquamation in the upper respiratory tract. When burned, PVC will have a detectable pungent odor. The combustion products of PVC, like those from most other natural and synthetic materials, must be considered toxic. Like most conventional materials including wood, paper and cotton, the major hazard is carbon monoxide. Carbon monoxide acts as an asphyxiant while hydrogen chloride is highly irritating. B) Under abnormal processing conditions (including equipment malfunctions or plug-up) decomposition of PVC compound may occur in an extruder, injec tion molding machine, or other processing equip ment, resulting in a characteristic whitish smoke which will contain hydrogen chloride and vapors from metallic stabilizers and other ingredients. In halation will result in irritation of the respiratory tract, eyes and skin resulting in coughing, pain, and inflammation. Employees involved in removing de composing materials should be provided with suitable air supplied respirators. Decomposing compound should be removed to a well-ventilated area, preferably outdoors, and thoroughly soaked with water. Stand safely back while dousing since water contacting the hot decomposing compound may result in an explosion-like burst of steam. Refer to Cumulativ Supplement June 1977, NIOSH Certified Equipment, NIOSH #77-195, fora listing of VCS516 NIOSH approved respirators. It can be obtained, no charge, from Publications Dissemination, DTS NIOSH 4676 Columbia Parkway Cincinnati, Ohio 45226 C) During typical break-down and clean-up of equip ment ?fter processing, PVC compound may be held at processing temperature for a short period. While this should not result in significant decomposition, it should be understood that the combined vapors from ail ingredients will be present. PVC compound cannot be held static in processing equipment under high heat or at processing temperature for ext nded periods of time. Decomposition will occur. During equipment clean-up operations, avoid in halation of fumes. Local exhaust ventilation should be provided to prevent significant employee exposure. D) Post-processing operations at your workplace or at your customer s workplace involving heat sufficient to result in polymer breakdown emitting smoke and fumes should always be conducted in a manner to avoid inhalation of fumes. Local exhaust ventilation should be provided to prevent significant employee exposure. Unusual Fire and Explosion Hazards The potential dust explosion hazard of PVC has been evaluated by BFGoodricn using the Hartmann Vertical Tube Apparatus developed by the Bureau of Mines. In this test resin is fluidized in a vertical tube using a stream of air. Ignition is accomplished using a high voltage alternating current spark applied across brass terminals. Research has also been reported by the Na tional Fire Protection Association (NFPA) based on equations using data from a battery of tests. PVC Resin: - Geon'* vinyl resins representing fine par ticle size (28 Microns: Geon 121), medium particle size (75 Microns: Geon1 140x31) and large particle size (130 Microns: Geon' 103EPF76) neither ig nited nor exploded in a test range of 0.1 2.0 gm/liter concentration using stand ard conditions of test. Fluidization be comes difficult at and above the 2.0 gm/liter level making it impractical to test at greater volumes. -The NFPA (Fire Protection Handbook, 14th Edition, pg. 3-112) shows "fine" par ticle size homopolymer PVC resin to have a low order of risk: Explosibility Index 0.1 (Weak) Ignition Sensitivity 0.1 (Weak) Explosion Severity < 0.1 (Weak) - These data indicate that typical homo polymer PVC resin has a very low order of explosion risk. As a precaution, it is prudent to employ standard safety measures used in handling finely divided organic powders. PVC - Cube C mpound, because of large par- Compound: tide size, does not represent an explo sion hazard. - Powder Compound, because of fine par ticle size fillers and additives or liquids added to the PVC resin, may have in creased dust explosion potential. Be cause of the wide variety of possible ingredient combinations, operations us ing plasticized or unplasticized powder compounds should be evaluated as the individual situation exists. -The NFPA Fire Protection Handbook (14th Ed., pg. 3-112) reports the following for a PVC (67%)/DOP (33%) mixture: Explosibility Index 2.9 (Strong) Ignition Sensitivity 3.6 (Strong) Explosion Severity 0.8 (Moderate) - Implement precautions to control or eliminate likely sources of ignition, such as static build-up. Maintain good house keeping, notably, ventilation, to prevent accumulation of .potentially explosive dust concentrations. Properly maintain and operate dust control devices. Ignition Characteristics (ASTM D-1929) PVC resin has a flash-ignition temperature of about 391*C (735F) and a self-ignition temperature of about 454*C (850*F). Because PVC polymer contains chlorine in the molecule, these materials are difficult to ignite and burn slowly. Like all organic materials, PVC is com bustible and can be forced to burn by continuous appli cation of intense heat. Like at) combustible materials, protect from open flame and maintain proper clearance when using portable heat -devices, etc. Safely store flammable liquids away from PVC. Flash Ignition Temperature: The lowest initial tem perature of air passing around the specimen at which sufficient combustible gas is evolved to be ig nited by a small external pilot flame. Self-Ignition Temperature: The lowest initial temper ature 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 sus tained glow. SECTION V HEALTH HAZARD DATA Threshold Limit Value None established. Effects of Overexposure Processing vapors may produce acute health ef fects in some individuals. The effects relate primari ly to eye, nose and throat irritation. Individuals with bronchial asthma and other types of chronic obstructive respiratory disease may develop bronchspasm if exposure is prolonged. VC5517 Emergency and First Aid Procedures If irritation persists, remove affected individual from the area. Call a physician. Provide protection before re-entry. If overexposure occurs, leave the area. Skin Sensitization Human patch tests conducted with numerous Geon' vinyl resins indicates these materials have a low order of toxicity and do not cause skin sen sitization. Vinyl Chloride Monomer (VCM) By a process called polymerization, vinyl chloride monomer, which is a gas at ordinary temperature and pressure, is converted into polyvinyl chloride (PVC) resin, which is a white powder. A small number of workers exposed for many years to large amounts of VCM gas developed a rare cancer of the liver called angiosarcoma. All confirmed VCM related cases have been among workers in plants that either manufacture VCM or convert VCM into PVC. OSHA has implemented regulations which also apply to PVC because small amounts of residual VCM remain in resins or compounds and potentially may be released into the workplace at mosphere during storage or processing. VCM Monitoring Requirements Current OSHA regulations require all facilities where PVC is processed (including blends of PVC with other polymers) or fabricated (with heat suffi cient to cause mass melting*) shall be monitored to determine concentrations of ambient VCM in the workplace atmosphere. These regulations require that no employee may be exposed to VCM concen trations greater than 1.0 ppm (part 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. Monitoring may be discontinued for any employee only when at least two consecutive determinations, made not less than five working days apart, show exposures for that employee at or below the action level. REFER TO OSHA REGULATIONS (IN CLUDING 1910.1017) FOR COMPLETE DETAILS. Since small quantities of VCM do remain in PVC resin, we recommend that periodic monitoring pro grams be conducted. If you choose to have monitor ing conducted by an independent laboratory, we suggest that the laboratory be one accredited by the American Industrial Hygiene Association. `"Mass melting" occurs when the entire structure is heated so that the physical integrity and form of the input material is lost. Places where VCM May Concentrate With the low level of residual VCM in today's resins and by following the guidelines provided in this bulletin, it is highly unlikely under normal cir cumstances that anyone engaged in handling or processing Geon1 vinyls will be exposed to ambient VCM concentrations above the OSHA "action level." There are, however, conditions under which VCM may accumulate to measurable amounts in the workplace atmosphere. Since VCM is volatile, it is released from the resin gradually in storage and more rapidly under heat and further processing. Open, handle, and use PVC resin and compound under well-ventilated conditions to avoid significant employee exposure. Areas where VCM might concentrate are: 1) Closed containers such as bulk railcars, bulk trucks, storage tanks, and drums. Vent the air space above the resin or compound and monitor for VCM; or, provide suitable respiratory'protection prior to exposure of personnel (See OSHA 1910.1017). 2) Storage areas for bagged or boxed PVC and places where incoming resins and compounds are unload ed, where packages are first opened, and where material is first melted. Provide suitable ventilation. 3) Processing areas such as compound preparation; extruding, curing, or coating operations, and other areas where heat is being applied. Provide suitable ventilation. VCM at low levels cannot be detected by odor. Suitable test equipment and methods must be used. Low VCM Content of Geon' Vinyls BFGoodrich has implemented continuing technical efforts to reduce the level of VCM in the work atmosphere, the environment, and in PVC resin. Ex tensive product and process improvements have resulted in General Purpose, EP-type, Dispersion and Mass Polymerized Blending resins with ex tremely low levels of residual VCM. Residual VCM in major types of Geon* vinyl resins are presented in Table 1. Studies in PVC processing and fabricating plants have shown exposures to be below the "action level." With current resins, in combination with ven tilation and work practice programs, it should be possible for a typical processing plant not to have to regulate the area. Compliance with OSHA regula tions require that a program of initial monitoring be implemented (See OSHA 1910.1017). BFGoodrich recommends that periodic monitoring be con ducted thereafter. Progress has also been made in reducing residual VCM in suspension grade blending and paste resins. Because of the unique characteristics of blending and paste resins, there is greater technical difficulty in stripping residual VCM without damag ing the polymer. Residual VCM in suspension grade blending and paste resins may result in detectable quantities of ambient VCM above the action level in storage and processing areas of the resin user's plant. The user should monitor personnel periodically and implement ventilation and work practice programs to prevent significant employee exposure and to comply with OSHA regulation 1910.1017. VC5518 SECTION VI REACTIVITY DATA Stability -- Stable. Decomposition Products -- See Section IV. Hazardous Polymerization -- Will Not Occur. Incompatibility Avoid contact of PVC resin or compound with acetal or acetal copolymers and with amine containing mate rials during processing. At processing conditions these materials are mutually destructive and involve rapid degradation of the products. 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 PROCEDURES Steps to be taken in case materia! is released or spilled PVC materials may be swept, shoveled, or vacuumed into containers for reuse or disposal. If conditions oc cur where dust is possible, employees should be sup plied with NIOSH approved respiratory protective de vices. (See Section VIII). Wast Disposal Method Sanitary landfill or incineration in accordance with fed eral, state, or local regulations. If incineration is used, recognition should be made that corrosive hydrogen chloride is generated. I SECTION vm | SPECIAL PROTECTION INFORMATION Ventilation Exhaust ventilation designed to pull vapors away from workers should be Installed at all mixing operations, the hot end and feed atea of processing equipment and at cut-off equipment. Ventilation should always be used to prevent routine inhalation of smoke, fumes or vapors from processing or other operations. Other operations to consider include regrind operations, thermoforming, heat sealing, soldering, and curing. We suggest that you obtain a copy of the NIOSH Rec ommended Industrial Ventilation Guidelines, GPO #017-033-00136-7. It can be obtained from Superintend ent of Documents, U.S. Government Printing Office, Washington, D.C. 20402. There is a fee for this publica tion ($3.90 as of August, 1979). Respiratory Protection -- Dust Operations involving possible exposure to airborne PVC particles should be evaluated as the individual situation exists. OSHA 1910.1000 states that if airborne concentrations of dust particles are found to exceed a total mass of 15 mg/mJ, or 5 mg/mJ respirable particles, appropriate engineering controls or NIOSH approved respiratory protection is recommended. Refer to Cumulative Supplement, June, 1977, NIOSH Certified Equipment described m Section IV. Other Protection Information 1) PVC resin'must be compounded with other ingre dients. If you purchase PVC resin, the other in gredients you select for compounding purposes may require special consideration, especially res piratory protection. You must determine to your own satisfaction that your techniques, processes and additives comply with applicable regulations. As we cannot be responsible for materials or operations outside of our direct control, we recommend you contact your additive supplier for necessary information regarding specific compounding ingre dients you select. 2) Safety glasses are recommended for all industrial workplaces. Special protective gloves and clothing are not required when handling Geon vinyl resins or compounds. Gloves should be worn when hand ling hot PVC. SECTION IX SPECIAL PRECAUTIONS 1) Vapors emitted during processing may condense on exhaust hoods, ductwork or other surfaces. Avoid skin contact with condensate during clean-up operations. Condensate may contain contaminants which may be toxic. Rubber gloves should be worn when cleaning condensate from exhaust hoods and other surfaces. 2) Observe good rules of personal industrial hygiene. Wash hands prior to eating. Do not store or consume food in processing areas. Do not use processing equipment to heat food. These precautions will help prevent ingestion of unknown contaminants. 3) The process of regrinding PVC scrap for re extrusion or waste disposal generally results in sub stantial heat. Cool regrind before placing it in con tainers. The excellent insulating quality of PVC will prevent heat in the center of a container from escap ing potentially resulting in slow thermal decomposi tion of the material. This may not only render the product unsatisfactory for further processing but also result in fumes and vapors from all ingredients being released Into the workplace atmosphere which can cause irritation of the respiratory tract, eyes and skin. 4) Prevent accumulations of PVC resin or compound in walkways and other areas where people walk to prevent slippery footing. VC5519 SECTION X TRANSPORTATION INFORMATION For transportation purposes, Geon* vinyl resins and compounds are not defined or designated as a hazard ous material by the U.S. Department of Transportation under Title 49 of the Code of Federal Regulations, 1977 edition.
