EXPOSURE


  • INHALATION
    		• Cough. Headache. Nausea. Sore throat.
    		Ventilation. Local exhaust.
    		Fresh air, rest.
  • SKIN
    		• Dry skin. Redness. Pain.
    		Protective gloves.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain.
    		Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Diarrhoea. Nausea. Vomiting.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give a slurry of activated charcoal in water to drink.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. If solid: Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Do NOT let this chemical enter the environment.
    		Separated from strong oxidants.

    UN Hazard Class: 9

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Reacts with strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (for vapour): 1 ppm; 7 mg/m3 (as TWA) 2 ppm; 14 mg/m3 (STEL) (ACGIH 1997).


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

    INHALATION RISK:
     A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20░C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The aerosol of this substance irritates the eyes and the respiratory tract.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact with skin may cause dermatitis.

    ENVIRONMENTAL
    DATA
         		The substance is very toxic to aquatic organisms. In the food chain important to humans, bioaccumulation takes place, specifically in fish. Avoid release to the environment in circumstances different to normal use.
    N O T E S
    Health effects of exposure to the substance have not been investigated. The substance has a strong disagreeable odour which may cause nausea.
