FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion.
NO contact with water, combustibles and reducing agents (see Chemical Dangers).
NO water. In case of fire in the surroundings: powder, carbon dioxide (see Notes).
EXPLOSION Risk of fire and explosion on contact with many substances (see Chemical Dangers).

In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position (see Notes).
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Burning sensation. Cough. Laboured breathing. Symptoms may be delayed (see Notes).
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Redness. Pain. Blisters. ON CONTACT WITH LIQUID: FROSTBITE.
    		Cold-insulating gloves. Protective clothing.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention (see Notes).
  • EYES
    		• Redness. Pain. Severe deep burns.
    		Face shield or eye protection in combination with breathing protection.
    		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 (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Fireproof if in building. Separated from incompatible substances (see Chemical Dangers). Cool. Dry.

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

    PHYSICAL DANGERS:
     The gas is heavier than air.

    CHEMICAL DANGERS:
     The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts violently with water producing toxic and corrosive vapours: ozone (see ICSC 0068) and hydrogen fluoride (see ICSC 0283). Reacts violently with ammonia, metals, oxidants, and many other materials, causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 1 ppm; 1.6 mg/m3 (as TWA) (ACGIH 1993-1994).
    TLV (as ceiling values): 2 ppm; 3.1 mg/m3 (STEL) (ACGIH 1993-1994).
    OSHA PEL: TWA 0.1 ppm (0.2 mg/m3)
    NIOSH REL: TWA 0.1 ppm (0.2 mg/m3)
    NIOSH IDLH: 25 ppm


    		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:
     Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of this gas may cause lung oedema (see Notes). The liquid may cause frostbite. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL

    Reacts violently with fire extinguishing agents such as water. 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 are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder). Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
