International Chemical Safety Cards VINYL CHLORIDE ICSC: 0082 Chloroethene Chloroethylene VCM C2H3Cl / H2C=CHCl Molecular mass: 62.5 (cylinder) ICSC #    0082 CAS #     75-01-4 RTECS # KU9625000 UN #        1086 (stabilized) EC #         602-023-00-7 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with powder, carbon dioxide. EXPLOSION Gas/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. EXPOSURE AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Dizziness. Drowsiness. Headache. Unconsciousness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN ON CONTACT WITH LIQUID: FROSTBITE. Protective gloves. Cold-insulating gloves. Protective clothing. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.  •EYES Redness. Pain. Safety goggles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Consult an expert! Ventilation. Remove all ignition sources. (Extra personal protection: complete protective clothing including self-contained breathing apparatus). Fireproof. Separated from incompatible materials (see Chemical Dangers). Cool. Store only if stabilized. Note: D F+ symbol T symbol R: 45-12 S: 53-45 UN Hazard Class: 2.1 SEE IMPORTANT INFORMATION ON BACK ICSC: 0082 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 2000. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards VINYL CHLORIDE ICSC: 0082 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS COMPRESSED LIQUEFIED GAS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The gas is heavier than air, and may travel along the ground; distant ignition possible. Vinyl chloride monomer vapours are uninhibited and may form polymers in vents or flame arresters of storage tanks, resulting in blockage of vents. CHEMICAL DANGERS: The substance can under specific circumstances form peroxides, initiating explosive polymerization. The substance will polymerize readily due to heating and under the influence of air, light, and on contact with a catalyst, strong oxidizing agents and metals such as copper and aluminium, with fire or explosion hazard. The substance decomposes on burning producing toxic and corrosive fumes ( hydrogen chloride , phosgene ). Attacks iron and steel in the presence of moisture. OCCUPATIONAL EXPOSURE LIMITS: TLV: 1 ppm; A1 (ACGIH 1999). OSHA PEL: 1910.1017 TWA 1 ppm C 5 ppm 15-minute NIOSH REL: Ca See Appendix A NIOSH IDLH: Potential occupational carcinogen No data ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: A harmful concentration of this gas in the air will be reached very quickly on loss of containment. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes. The liquid may cause frostbite. The substance may cause effects on the central nervous system . Exposure could cause lowering of consciousness. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the liver, spleen, blood andperipheral blood vessels, and tissue and bones of the fingers. This substance is carcinogenic to humans. PHYSICAL PROPERTIES Boiling point: -13°C Melting point: -154°C Relative density (water = 1): (liquid) 0.9 Density: (vapour) at 15°C 8 g/l Solubility in water: none Relative vapour density (air = 1): 2.2 Flash point: -78°C c.c. Auto-ignition temperature: 472°C Explosive limits, vol% in air: 3.6-33 Octanol/water partition coefficient as log Pow: 0.6 ENVIRONMENTAL DATA This substance may be hazardous to the environment; special attention should be given to ground water . N O T E S Depending on the degree of exposure, periodic medical examination is indicated. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT use in the vicinity of a fire or a hot surface, or during welding. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
