TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking.  Use 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.  Use 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.  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   Do not eat, drink, or smoke during work.  Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING

IMPORTANT DATA
Physical State; Appearance
COMPRESSED LIQUEFIED GAS WITH PUNGENT ODOUR. 

Physical dangers
The vapour is heavier than air. 

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

Occupational exposure limits
TLV: 0.5ppm as TWA; A2 (suspected human carcinogen); (ACGIH 2001). 

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 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.
