TYPES OF
HAZARD/
EXPOSURE
ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
  • Dizziness. Drowsiness.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • Dry skin.
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • 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
  • Nausea (further see Inhalation).
    Do not eat, drink, or smoke during work.
    Rinse mouth. 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 dry sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: filter respirator for organic gases and vapours).
    Fireproof. Separated from strong oxidants.

    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. As a result of flow, agitation, etc., electrostatic charges can be generated.

    CHEMICAL DANGERS:
    Reacts violently with strong oxidants, causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 400 ppm; 1610 mg/m3 (ACGIH 1996).


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

    INHALATION RISK:


    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes and the skin. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. The substance may cause effects on the central nervous system. Exposure could cause lowering of consciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    The liquid defats the skin.
