FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Above 67°C explosive vapour/air mixtures may be formed.
Above 67°C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE! AVOID EXPOSURE OF (PREGNANT) WOMEN!

  • INHALATION
  • Burning sensation. Cough. Nausea. Headache. Shortness of breath. Dizziness.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Half-upright position. 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. Blurred vision. Severe deep burns.
    Safety goggles, 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. Vomiting. Burning sensation behind the breastbone.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking liquid in covered non-metallic containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Separated from food and feedstuffs, and incompatible materials: see chemical dangers. Dry. Ventilation along the floor. Store only if stabilized.
    Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance will polymerize under the influence of all common metals except nickel and lead, with evolution of corrosive fumes (hydrogen chloride - see ICSC # 0163), with fire or explosion hazard. On combustion, forms toxic and corrosive fumes (hydrogen chloride). Reacts vigorously with strong oxidants. Reacts with water, producing corrosive fumes (hydrogen chloride - see ICSC # 0163). Attacks many metals in presence of water.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 1 ppm; 5.2 mg/m3 (as TWA) (ACGIH 1992-1993).


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

    INHALATION RISK:
    A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C; on spraying much faster.

    EFFECTS OF SHORT-TERM EXPOSURE:
    Tear drawing. The substance is corrosive to the eyes. The vapour irritates the eyes, the skin and the respiratory tract. Inhalation of the vapour or aerosol may cause lung oedema (see Notes). The substance may cause effects on the central nervous system , resulting in unconsciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The substance may have effects on the liver and kidneys , resulting in severe damage. Tumours have been detected in experimental animals but may not be relevant to humans (see Notes). Animal tests show that this substance possibly causes toxic effects upon human reproduction.

    ENVIRONMENTAL
    DATA

    NOTES
    Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. The odour warning when the exposure limit value is exceeded is insufficient.
