SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible.

In case of fire in the surroundings: do not use water. Fire fighters should wear complete protective clothing including self-contained breathing apparatus.
EXPLOSION

In case of fire: keep cylinder cool by spraying with water but NO direct contact with water. Fire fighters should wear complete protective clothing including self-contained breathing apparatus.
EXPOSURE
STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN!

  • INHALATION
    		• Burning sensation of nose and throat, laboured breathing. Symptoms may be delayed (see Notes).
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest, half-upright position, artificial respiration if indicated, and refer for medical attention.
  • SKIN
    		• LIQUID MAY BE ABSORBED! Redness. ON CONTACT WITH LIQUID: FROSTBITE.
    		Cold-insulating gloves, protective clothing.
    		Remove contaminated clothes, ON FROSTBITE: rinse with plenty of water, do NOT remove clothes, rinse and then wash skin with water and soap, and refer for medical attention if irritation persists.
  • EYES
    		• Redness.
    		Safety spectacles.
    		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, NEVER direct water jet on liquid (extra personal protection: self-contained breathing apparatus).
    		Fireproof if in building, cool.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS, HYGROSCOPIC, COMPRESSED LIQUEFIED GAS , WITH CHARACTERISTIC ODOUR. FUMES WHEN EXPOSED TO MOIST AIR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Upon heating, toxic fumes are formed. Reacts with water or acids, producing heat and highly toxic fumes.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 0.1 ppm; 0.68 mg/m3 (as TWA) (skin) (ACGIH 1992-1993)
    OSHA PEL: none
    NIOSH REL: TWA 0.1 ppm (0.7 mg/m3) skin
    NIOSH IDLH: No data


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

    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 the substance may cause lung oedema (see Notes). Rapid evaporation of the liquid may cause frostbite.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the kidneys. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

    ENVIRONMENTAL
    DATA
    NOTES
    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 is therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. The odour warning when the exposure limit value is exceeded is insufficient. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
