  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Gas/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.  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, water spray. See Notes.  In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Dizziness. Drowsiness. Headache. Unconsciousness. Blurred vision. Numbness. Tingling sensation.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer immediately 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. Refer immediately for medical attention. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Remove all ignition sources. Remove vapour cloud with fine water spray. NEVER direct water jet on liquid.

PHYSICAL & CHEMICAL INFORMATION

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. Vapours are uninhibited and may polymerize, causing blockage of vents. 

Chemical dangers
The substance can form explosive peroxides under specific circumstances. The substance readily polymerizes 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. This generates fire or explosion hazard. Decomposes on burning. This produces toxic and corrosive fumes of hydrogen chloride and phosgene. Attacks iron and steel in the presence of moisture.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The liquid may cause frostbite. The substance is irritating to the eyes. The substance may cause effects on the central nervous system. This may result in lowering of consciousness, convulsions and seizures. Medical observation is indicated. 

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
The substance may have effects on the liver, spleen, blood, peripheral blood vessels and tissue and bones of the fingers. Animal tests show that this substance possibly causes toxicity to human reproduction or development. This substance is carcinogenic to humans. 


Occupational exposure limits
TLV: 1 ppm as TWA; A1 (confirmed human carcinogen).
MAK: carcinogen category: 1 

ENVIRONMENT
This substance may be hazardous to the environment. Special attention should be given to ground water contamination. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
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.
Large fires of this material are practically inextinguishable: use water spray or fog.
