TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) 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!

  • INHALATION
    		• Confusion. Drowsiness. Nausea. Unconsciousness.
    		Ventilation (not if powder). Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves.
    		Rinse skin with plenty of water or shower.
  • EYES
    		• Redness.
    		Safety spectacles or eye protection in combination with breathing protection if powder.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Vomiting (further see Inhalation).
    		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; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P3 filter respirator for toxic particles).
    		Separated from strong bases, food and feedstuffs. Keep in the dark.
    		Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on burning producing toxic and corrosive fumes including hydrochloric acid. Reacts with strong bases producing chloroform.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

    INHALATION RISK:
     A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system, kidneys, liver and the cardiovascular system , resulting in impaired functions. Exposure may result in unconsciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point (decomposes): 97°C
    Melting point: 57-60°C
    Relative density (water = 1): 1.9
    		 Solubility in water: very good
    Octanol/water partition coefficient as log Pow: 0.99
    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to water organisms.
    N O T E S
    Use of alcoholic beverages enhances the harmful effect. Escre, Noctec, Nycton, Somnos, Lorinal, Chloraldurat are trade names.
