FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Foam, alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION Above 28°C explosive vapour/air mixtures may be formed.
Above 28°C 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
    		• Cough. Dizziness. Drowsiness. Headache.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Dry skin.
    		Protective gloves.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
    		• Redness. Pain. Blurred vision.
    		Face shield 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
    		• Diarrhoea. Nausea. Vomiting (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give plenty of water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Wash away remainder with plenty of water (extra personal protection: A filter respirator for organic vapour).
    		Fireproof. Separated from strong oxidants.

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     Reacts with strong oxidants, such as chromium trioxide, causing fire hazard. Attacks some plastic and rubber.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 50 ppm; 152 mg/m3 (as TWA) (ACGIH 1994-1995).
    MAK: 100 ppm; 300 mg/m3 (1994).
    OSHA PEL: TWA 100 ppm (300 mg/m3)
    NIOSH REL: TWA 50 ppm (150 mg/m3)
    NIOSH IDLH: 1600 ppm


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its vapour, 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 vapour of this substance irritates the eyes and the respiratory tract. The substance may cause effects on the central nervous system. Exposure to high concentrations could cause lowering of consciousness.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact with skin may cause dermatitis.
