TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion.  NO open flames, NO sparks and NO smoking. NO contact with combustible substances.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with combustible substances.  Closed system, ventilation, explosion-proof electrical equipment and lighting.  Combat fire from a sheltered position. 
 
EXPOSURE   STRICT HYGIENE!   
Inhalation Sore throat. Cough. Headache. Shortness of breath. Laboured breathing.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves.  ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention . 
Eyes Redness. Pain.  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 OR BLUISH GAS WITH CHARACTERISTIC ODOUR. 

Physical dangers
The gas is heavier than air. 

Chemical dangers
Decomposes on warming. This produces oxygen. This generates fire and explosion hazard. Reacts violently with inorganic and organic compounds. This generates fire and explosion hazard. Attacks rubber. 

Occupational exposure limits
TLV (light work): 0.1ppm as TWA;.
TLV (moderate work): 0.08ppm as TWA;.
TLV (heavy work): 0.05ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2009).
MAK: Carcinogen category: 3B; (DFG 2008). 

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 and respiratory tract. The substance may cause effects on the central nervous system. This may result in impaired vigilance and performance. Inhalation of the gas may cause lung oedema. See Notes. The effects may be delayed. The liquid may cause frostbite. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of the gas may cause effects on the lungs. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: -112°C
Melting point: -193°C
Solubility in water: none
Relative vapour density (air = 1): 1.6  
This substance may be hazardous to the environment. Special attention should be given to plants. 

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 are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
Card has been partially updated in April 2010: see Fire fighting; GHS classification.
