TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, water spray, 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
PREVENT GENERATION OF MISTS! STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Drowsiness. Headache. Nausea. Unconsciousness.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Redness. Roughness.
    		Protective gloves.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
  • EYES
    		• Redness.
    		Safety goggles, 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
    		• Abdominal pain. (See Inhalation).
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. 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 (extra personal protection: filter respirator for organic gases and vapours).
    		Fireproof. Separated from strong oxidants. Cool.

    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 decomposes on heating, on burning and on contact with hot surfaces, producing corrosive and toxic fumes including phosgene, hydrogen chloride. Reacts violently with strong oxidants, dimethyl sulfoxide causing fire and explosion hazard. Attacks rubber and some plastics.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 10 ppm; 46 mg/m3 (as TWA) (ACGIH 1996).
    MAK: 10 ppm; 50 mg/m3; (1995).
    OSHA PEL: TWA 75 ppm (350 mg/m3)
    NIOSH REL: See Appendix D
    NIOSH IDLH: 1000 ppm


    		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:
     Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. Exposure may result in unconsciousness. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the central nervous system, blood, liver, and kidneys.

    ENVIRONMENTAL
    DATA
         		It is strongly advised not to let the chemical enter into the environment.
    N O T E S
    The odour warning when the exposure limit value is exceeded is insufficient. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
