3. HAZARD INDENTIFICATION

* * * EMERGENCY OVERVIEW * * *
Liquid and gas under pressure.
Can cause rapid suffocation.
May cause frostbite.

POTENTIAL HEALTH EFFECTS

ROUTES OF ENTRY: Inhalation

ACUTE EFFECTS: Inhalation may cause asphyxiation due to dilution of available oxygen in the air. Symptoms include lightheadedness, giddiness, disorientation, shortness of breath, and possible cardiac arrhythmias. Skin and eye contact with liquid may cause frostbite. Pressure drop through valves and piping may cause extreme cold and frostbite on contact.

CHRONIC EFFECTS: None known

MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Heart disease. Cardiovascular problems.

OTHER EFFECTS OF OVEREXPORSURE: None

CARCINOGENICITY (US ONLY):
    NTP - No
    IARC MONOGRAPHS - No
    OSHA REGULATED - No
4. FIRST AID MEASURES

INHALATION: Immediately remove victim to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen.

EYE CONTACT: Immediately flush with copious amounts of water for at least 15 minutes.

SKIN CONTACT: If frostbite occurs, flush affected areas with lukewarm water.

INGESTION: None

IN EVENT OF EXPOSURE, CONSULT A PHYSICIAN

NOTE TO PHYSICIAN: None
