TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep cylinder cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position. 
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Burning sensation. Chest tightness. Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed. See Notes.  Use closed system or ventilation.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Pain. ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves.  Remove contaminated clothes. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision.  Wear face shield 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.

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

Physical dangers
The gas is heavier than air. 

Chemical dangers
Decomposes above 300°C . Decomposes on contact with water or moisture. This produces toxic and corrosive gases of of carbon monoxide and hydrogen chloride. Reacts with aluminium and isopropyl alcohol. 

Occupational exposure limits
TLV: 0.1ppm as TWA; (ACGIH 2002).
EU OEL ( selected): 0.02 ppm, 0.08 mg/m³ as TWA; 0.1 ppm, 0.4 mg/m³ as STEL;.
EU OEL ( selected): 0.02 ppm, 0.08 mg/m³ as TWA; 0.1 ppm, 0.4 mg/m³ as STEL;.
EU OEL ( selected): 0.02 ppm, 0.08 mg/m³ as TWA; 0.1 ppm, 0.4 mg/m³ as STEL;. 

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, skin and respiratory tract. Inhalation of of this gas may cause lung oedema. See Notes. The effects may be delayed. Exposure at high levels could cause death. Medical observation is indicated. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 8°C
Melting point: -118°C
Relative density (water = 1): 1.4
Solubility in water: reaction
Vapour pressure, kPa at 20°C: 161.6
Relative vapour density (air = 1): 3.4  
 

NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder).
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Card has been partially updated in January 2008: see Occupational Exposure Limits.
