NO open flames, NO sparks, and NO smoking. Water spray, foam, carbon dioxide. EXPLOSION In case of fire: keep cylinder cool by spraying with water. EXPOSURE AVOID ALL CONTACT!  •INHALATION Cough. Sore throat. Dizziness. Confusion. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. ON CONTACT WITH LIQUID: FROSTBITE. Cold-insulating gloves. 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. Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Evacuate danger area! Ventilation. Remove all ignition sources. Chemical protection suit including self-contained breathing apparatus. Fireproof. Cool. Keep in a well-ventilated room. Separated from oxidants. Store only if stabilized.

International Chemical Safety Cards VINYL BROMIDE ICSC: 0597 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COMPRESSED LIQUEFIED GAS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air . CHEMICAL DANGERS: Reacts violently with oxidants . The substance decomposes on burning producing toxic gases . The substance polymerizes under the influence of heat or light . OCCUPATIONAL EXPOSURE LIMITS: TLV: as TWA 0.5 ppm A2 (ACGIH 2001). 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: On loss of containment, a harmful concentration of this gas in the air will be reached very quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes . The substance may cause effects on the central nervous system . Rapid evaporation of the liquid may cause frostbite. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is probably carcinogenic to humans. PHYSICAL PROPERTIES Boiling point: 15.6°C Melting point: -139.5°C Relative density (water = 1): 1.49 Solubility in water: none Vapour pressure, kPa at 20°C: 119 Relative vapour density (air = 1): 3.7 Flash point: flammable gas Auto-ignition temperature: 530°C Explosive limits, vol% in air: 9-15 Octanol/water partition coefficient as log Pow: 1.57 ENVIRONMENTAL DATA N O T E S An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
