TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.  NO open flames.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Confusion. Dizziness. Drowsiness. Unconciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Inhalation.    Rest.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. 

Chemical dangers
Decomposes on heating. This produces phosgene, hydrogen fluoride and hydrogen chloride. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 3B; (DFG 2008). 

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

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes. The substance may cause effects on the central nervous system and cardiovascular system. This may result in narcosis and cardiac disorders. 

Effects of long-term or repeated exposure
The substance may have effects on the liver. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA

Melting point: -107°C
Relative density (water = 1): 1.5
Solubility in water, g/100ml at 25°C: 0.21
Vapour pressure, Pa at 25°C: 14
Relative vapour density (air = 1): 6.4  
This substance may be hazardous to the environment. Special attention should be given to its impact on the ozone layer. It is strongly advised not to let the chemical enter into the environment because it is persistent. Avoid release to the environment in circumstances different to normal use. 

NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
Card has been partially updated in February 2009: see Occupational Exposure Limits.
