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 Risk of fire and explosion (see Chemical Dangers).

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

  • INHALATION
  • Dizziness. Drowsiness. Headache. Nausea.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! Redness. Pain.
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
  • Redness. Pain.
    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 pain. Diarrhoea (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! 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. Do NOT let this chemical enter the environment (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Separated from metals (see Chemical Dangers), fluorine, food and feedstuffs. Ventilation along the floor.
    Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:
    The vapour is heavier than air.

    CHEMICAL DANGERS:
    On contact with hot surfaces or flames this substance decomposes forming toxic and irritating fumes (hydrogen chloride, ICSC # 0163; chlorine, ICSC # 0126; phosgene, ICSC # 0007). Reacts violently with some metals such as aluminium, barium, magnesium, potassium, sodium, with fluorine and other substances, causing fire and explosion hazard. Attacks copper, lead and zinc.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV (as TWA): 5 ppm; 31 mg/m3 A2 (skin) (ACGIH 1992-1993).
    MAK: 10 ppm; 65 mg/m3; II,1, H, D (1992).
    MAK: class III B (1992).


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes. The substance may cause effects on the liver, kidneys and the central nervous system , resulting in unconsciousness. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis. This substance is possibly carcinogenic to humans.
    PHYSICAL
    PROPERTIES
    Boiling point: 76.5C
    Melting point: -23C

    Solubility in water, g/100 ml at 20C: 0.1
    Vapour pressure, kPa at 20C: 12.2
    Relative vapour density (air = 1): 5.3
    Relative density of the vapour/air-mixture at 20C (air = 1): 1.5

    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to water.
    NOTES
    Use of alcoholic beverages enhances the harmful effect. Depending on the degree of exposure, periodic medical examination is indicated. 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. Ascordin, Katarin, Tetracol, Chlorasol are trade names.
