  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable.  Gas/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting.  Use water spray, foam, carbon dioxide.  In case of fire: keep cylinder cool by spraying with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Incoordination. Lethargy. Nausea. Vomiting.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves. Protective clothing.  Rinse and then wash skin with water and soap. Rinse skin with plenty of water or shower for at least 15 minutes. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer immediately for medical attention. 
Eyes Redness. Pain.  Wear 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 refer for medical attention. 
Ingestion      

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid. Remove fumes with fine water spray. Do NOT wash away into sewer.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS GAS OR COMPRESSED LIQUEFIED GAS WITH PUNGENT ODOUR. 

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Reacts violently with oxidants. Decomposes on burning. This produces toxic gases. The substance polymerizes under the influence of heat and light. 

Formula: C2H3Br / CH2=CHBr
Molecular mass: 106.96
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  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Effects of short-term exposure
Rapid evaporation of the liquid may cause frostbite. The substance is irritating to the eyes. The substance may cause effects on the central nervous system. 

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment. 

Effects of long-term or repeated exposure
This substance is probably carcinogenic to humans. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.5 ppm as TWA; A2 (suspected human carcinogen).
EU-OEL: 4.4 mg/m3, 1 ppm as TWA 

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately. 

NOTES
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.
