EXPOSURE
AVOID ALL CONTACT!

  • INHALATION
    		• Burning sensation. Cough. Shortness of breath. Sore throat.
    		Local exhaust or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Redness. Pain. Blisters.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain. Severe deep burns.
    		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. Burning sensation. Sore throat.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from strong oxidants, food and feedstuffs. Ventilation along the floor.
    		Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:
     The vapour is heavier than air.

    CHEMICAL DANGERS:
     On combustion, forms corrosive gas (hydrogen chloride). Upon heating, toxic fumes are formed. Reacts violently with strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

    INHALATION RISK:
     No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Exposure to high level may result in death.
