TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Gives off toxic and corrosive vapours in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!

  • INHALATION

    		• Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED!
    		Protective gloves.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES

    		• Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION

    		• Do not eat, drink, or smoke during work.
    		Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place.
    		Separated from metals: see Chemical Dangers, and from food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS CRYSTALS , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating above 300°C producing toxic and corrosive fumes, phosgene (see ICSC # 0007) and hydrogen chloride (see ICSC # 0163). Reacts violently with zinc, aluminium powder and sodium. Attacks iron in the presence of moisture.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 1 ppm; 9.7 mg/m3 skin (ACGIH 1992-1993).
    OSHA PEL: TWA 1 ppm (10 mg/m3) skin
    NIOSH REL: Ca TWA 1 ppm (10 mg/m3) skin See Appendix A See Appendix C (Chloroethanes)
    NIOSH IDLH: Potential occupational carcinogen 300 ppm


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

    INHALATION RISK:
     A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     Exposure could cause unconsciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the liver and kidneys. Exposure at far above the OEL may have effects on the central nervous system, inducing tremors and ataxia.
    PHYSICAL
    PROPERTIES
    Sublimation point: 183-185°C
    Relative density (water = 1): 2.1
    Solubility in water: none
    Vapour pressure, Pa at 20°C: 53
    		 Relative vapour density (air = 1): 8.2
    Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0
    Octanol/water partition coefficient as log Pow: 3.9
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to fish.
    NOTES
    According to ACGIH this substance belongs to group A2 indicating suspected human carcinogen. Use of alcoholic beverages enhances the harmful effect. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
