FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Above 27░C explosive vapour/air mixtures may be formed.
Above 27░C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

  • INHALATION
    		• Dizziness. Drowsiness. Headache. Unconsciousness.
    		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. Pain.
    		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. Burning sensation (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    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.
    		Fireproof. Separated from strong oxidants.

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

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

    CHEMICAL DANGERS:
     Reacts violently with strong oxidants such as nitric acid.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 100 ppm; 434 mg/m3 (as TWA) (ACGIH 1993-1994).
    TLV (as STEL): 150 ppm; 651 mg/m3 (ACGIH 1993-1994).


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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes. Exposure far above the OEL may result in central nervous system depression, unconsciousness and death.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The liquid defats the skin. The substance may have effects on the central nervous system , resulting in decreased learning ability.
