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 combustible materials such as oils or fats.

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

    PHYSICAL STATE; APPEARANCE:
    COMPRESSED 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:


    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Lungs may be affected by inhalation of high concentrations. Symptoms may be delayed.
