TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

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


  • INHALATION
    		• Drowsiness. Unconsciousness.
    		Ventilation.
    		Fresh air, rest. Artificial respiration if indicated. 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
    		• ON CONTACT WITH LIQUID: FROSTBITE.
    		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
    Ventilation. Do NOT let this chemical enter the environment.
    		Fireproof if in building.

    PHYSICAL STATE; APPEARANCE:
     LIQUEFIED COMPRESSED GAS , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:
     The gas is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen.

    CHEMICAL DANGERS:
     The substance decomposes on contact with open flames or very hot surfaces, producing toxic gases including phosgene, hydrogen fluoride, hydrogen chloride, hydrogen bromide.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

    INHALATION RISK:
     On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas.

    EFFECTS OF SHORT-TERM EXPOSURE:
     Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the cardiovascular system , resulting in cardiac disorders.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: -4░C
    Melting point: -160.5░C
    Solubility in water: none
    		 Relative vapour density (air = 1): 5.7
    Octanol/water partition coefficient as log Pow: 2.1
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.
    N O T E S
    High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
