EXPOSURE


  • INHALATION
    		• Cough. Dizziness. Headache. Nausea. Sore throat.
    		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.
    		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

    		• Do not eat, drink, or smoke during work.
    		Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking and spilled liquid in sealable metal or glass containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
    		Fireproof. Separated from oxidants. Cool.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS OR YELLOWISH 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 slowly on contact with air or moisture producing acetic acid and n-butanol. Reacts violently with strong oxidants causing fire and explosion hazard. Attacks many plastics and resins.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 150 ppm; 713 mg/m3 (as TWA) (ACGIH 1997).
    TLV (as (STEL)): 200 ppm; 950 mg/m3 (ACGIH 1997).
    MAK: 100 ppm; 480 mg/m3 (1997).
    OSHA PEL: TWA 150 ppm (710 mg/m3)
    NIOSH REL: TWA 150 ppm (710 mg/m3) ST 200 ppm (950 mg/m3)
    NIOSH IDLH: 1700 ppm LEL


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

    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 and the respiratory tract. Exposure far above OEL could cause lowering of consciousness.

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