SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Extremely flammable.
NO open flames, NO sparks, and NO smoking. NO contact with hot surfaces.
AFFF. Alcohol-resistant foam. Powder. 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


  • INHALATION
    		• Drowsiness. Headache. Unconsciousness. Vomiting.
    		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. Pain.
    		Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Dizziness. Drowsiness. Vomiting.
    		Do not eat, drink, or smoke during work.
    		Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: A/P2 filter respirator for organic vapour and harmful dust).
    		Fireproof. Separated from strong oxidants. Cool. Dry. Keep in the dark. Store only if stabilized.
    		Airtight.

    PHYSICAL STATE; APPEARANCE:
     VERY VOLATILE, HYGROSCOPIC, 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:
     The substance can form explosive peroxides under the influence of light and air. Reacts violently with oxidants causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 400 ppm; 1210 mg/m3 (as TWA); 500 ppm; 1520 mg/m3 (STEL) (ACGIH 1993-1994).
    PDK: 300 mg/m3 (USSR 1988).
    MAK: 400 ppm; 1200 mg/m3; (1992).


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes and the respiratory tract. 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 , resulting in narcosis.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The liquid defats the skin. The substance may have effects on the central nervous system. Caution, exposures may become addictive!
