SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.
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. Use reduced-sparking handtools.
In case of fire: keep cylinder cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

  • INHALATION
    		• Abdominal cramps. Dizziness. Dullness. Headache.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! 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 skin with plenty of water or shower. Refer for medical attention.
  • EYES
    		• Redness. Pain. Blurred vision.
    		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
    		• Abdominal cramps. Headache. Sore throat (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give plenty of water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! Ventilation (extra personal protection: self-contained breathing apparatus).
    		Fireproof. Separated from (see Chemical Dangers).
    		Special insulated cylinder. Special fittings.

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

    PHYSICAL DANGERS:
     The gas is heavier than air and may travel along the ground; distant ignition possible.

    CHEMICAL DANGERS:
     The substance decomposes on heating or on burning producing toxic gases (hydrogen chloride - see ICSC # 0163, phosgene - see ICSC # 0007). Reacts violently with oxidants, alkaline metals, calcium, magnesium, aluminum powder, and zinc. Reacts with water or steam producing corrosive fumes of hydrogen chloride.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as TWA): 1000 ppm; 2640 mg/m3 (ACGIH 1992-1993).
    MAK: 1000 ppm; 2600 mg/m3; (1992).
    OSHA PEL: TWA 1000 ppm (2600 mg/m3)
    NIOSH REL: Handle with caution in the workplace. See Appendix C (Chloroethanes)
    NIOSH IDLH: 3800 ppm LEL


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

    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 substance irritates the eyes, the skin and the respiratory tract. Inhalation of vapour may cause narcotic effects. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the nervous system, liver, and kidneys.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: 12.5°C
    Melting point: -142°C
    Relative density (water = 1): 0.918
    Solubility in water, g/100 ml at 20°C: 0.574
    Vapour pressure, kPa at 20°C: 133.3
    		 Relative vapour density (air = 1): 2.22
    Flash point: -50°C (c.c.)
    Auto-ignition temperature: 510°C
    Explosive limits, vol% in air: 3.6-14.8
    Octanol/water partition coefficient as log Pow: 1.54
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to water and air.
    NOTES
    Use of alcoholic beverages enhances the harmful effect. Depending on the degree of exposure, periodic medical examination is indicated. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Rinse contaminated clothes (fire hazard) with plenty of water. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
