TYPES OF
HAZARD/
EXPOSURE
ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable. Heating will cause rise in pressure with risk of bursting.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 60C explosive vapour/air mixtures may be formed.
Above 60C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Dizziness. Drowsiness. Dullness. Headache. Sore throat.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • Dry skin. Redness.
    Protective gloves.
    Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
  • Redness.
    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. Nausea. Vomiting.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Ventilation. 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 (extra personal protection: self-contained breathing apparatus).
    Separated from strong oxidants, strong acids. Well closed. Keep in a well-ventilated room. Store only if stabilized.

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

    PHYSICAL DANGERS:
    The vapour is heavier than air and may travel along the ground; distant ignition possible.

    CHEMICAL DANGERS:
    The substance may polymerize due to warming with fire or explosion hazard. Reacts with strong oxidants and strong acids.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 50 ppm; 242 mg/m3 (as TWA); 100 ppm; 483 mg/m3 (as STEL) (ACGIH 1996).


    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 be reached rather slowly on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the nervous system.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis. The liquid defats the skin. The substance may have effects on the liver and kidneys , resulting in tissue lesions.
