TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. 

In case of fire in the surroundings: use appropriate extinguishing media. 
EXPLOSION

In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 
EXPOSURE
STRICT HYGIENE! 

Inhalation Abdominal pain. Cough. Headache. Drowsiness. Burning sensation. Nausea. Dizziness. Confusion. Blue skin. Blue lips or finger nails. Shortness of breath. Convulsions. Unconsciousness. Symptoms may be delayed (see Notes).

NITRIC OXIDE ICSC: 1311
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE: 
COLOURLESS COMPRESSED GAS

CHEMICAL DANGERS: 
The substance is a strong oxidant and reacts with combustible and reducing materials. On contact with air it emits nitrogen dioxide.

OCCUPATIONAL EXPOSURE LIMITS: 
TLV: 25 ppm as TWA; BEI issued; (ACGIH 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: 
The substance is irritating to the eyes and the respiratory tract. Inhalation of the substance may cause lung oedema (see Notes). The substance may cause effects on the blood, resulting in formation of methaemoglobin. Exposure may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: 
Lungs may be affected by repeated or prolonged exposure.
PHYSICAL PROPERTIES
Boiling point: -151.8℃
Melting point: -163.6℃
Solubility in water, ml/100 ml at 0℃: 7.4
Relative vapour density (air = 1): 1.04
ENVIRONMENTAL DATA

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. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. No odour warning if toxic concentrations are present. 
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Emergency Response.
