FIRE FIGHTING
FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking.
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with powder, carbon dioxide.
EXPLOSION Gas/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state.
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE


  • INHALATION
    		• Drowsiness.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• 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
    		• 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
    Evacuate danger area! Consult an expert! Ventilation. NEVER direct water jet on liquid (extra personal protection: self-contained breathing apparatus).
    		Fireproof. Cool.

    PHYSICAL STATE; APPEARANCE:
     ODOURLESS COLOURLESS COMPRESSED LIQUEFIED GAS.

    PHYSICAL DANGERS:
     The gas is heavier than air and may travel along the ground; distant ignition possible, and may accumulate in low ceiling spaces causing deficiency of oxygen.

    CHEMICAL DANGERS:

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 800 ppm; 1900 mg/m3 (ACGIH 1996).
    MAK: 1000 ppm; 2350 mg/m3; (1993).
    OSHA PEL: none
    NIOSH REL: TWA 800 ppm (1900 mg/m3)
    NIOSH IDLH: No data


    		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:
     The liquid may cause frostbite.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: -1°C
    Melting point: -138°C
    Relative density (water = 1): 0.6
    Solubility in water, ml/100 ml at 20°C: 3.25
    Vapour pressure, kPa at 21.1°C: 213.7
    		 Relative vapour density (air = 1): 2.1
    Flash point: Flammable Gas
    Auto-ignition temperature: 287°C
    Explosive limits, vol% in air: 1.8-8.4
    ENVIRONMENTAL
    DATA
    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. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. The measures mentioned in section PREVENTION are applicable to production, filling of cylinders, and storage of the gas.
