TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames. NO contact with hot surfaces.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep cylinder cool by spraying with water. 
 
EXPOSURE      
Inhalation Dizziness. Drowsiness. Lethargy.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves.  ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. 
Eyes   Wear safety goggles.

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

Physical dangers
 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: 1000 ppm, 4200 mg/m³; Peak limitation category: II(8); Pregnancy risk group: C; (DFG 2004). 

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
Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system and cardiovascular system. This may result in cardiac disorders. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: -26°C
Melting point: -101°C
Solubility in water: none
Vapour pressure, kPa at 25°C: 630
Relative vapour density (air = 1): 3.5
Octanol/water partition coefficient as log Pow: 1.06  
This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Card has been partly updated in April 2005.
