SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Heating will cause rise in pressure with risk of bursting.
NO open flames, NO sparks, and NO smoking. NO contact with flammable substances. NO contact with fuels and other combustible materials.
In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION Risk of fire and explosion on contact with combustuble materials such as oils or fats.

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


  • INHALATION
    		• Burning sensation.

    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Pain. Serious frostbite. ON CONTACT WITH LIQUID: FROSTBITE.
    		Cold-insulating gloves. Protective clothing.
    		ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
  • EYES
    		• Redness. Pain. Severe deep burns.
    		Safety goggles, face shield.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION



    • SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! Ventilation. Do NOT absorb in saw-dust or other combustible absorbents. NEVER direct water jet on liquid.
    		Fireproof. Separated from combustible and reducing substances. Cool.
    		Special insulated cylinder.

    PHYSICAL STATE; APPEARANCE:
     DEEPLY REFRIGERATED LIQUID GAS.

    PHYSICAL DANGERS:
     The gas is heavier than air.

    CHEMICAL DANGERS:
     The substance is a strong oxidant and reacts violently with combustible and reducing materials, with risks of fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation and through the skin.

    INHALATION RISK:

    EFFECTS OF SHORT-TERM EXPOSURE:
     Rapid evaporation of the liquid may cause frostbite.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: -183░C
    Melting point: -218.4░C
    Solubility in water: moderate (3.1 ml/100 ml at 20░C)
    		 Relative vapour density (air = 1): 1.43
    Octanol/water partition coefficient as log Pow: 0.65
    ENVIRONMENTAL
    DATA
    NOTES
    Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. 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. Also consult ICSC # 0138.
