EXPOSURE


  • INHALATION
    		• Dizziness, dullness, headache, nausea.
    		Ventilation.
    		Fresh air, rest. Artificial respiration if indicated.
  • SKIN
    		• MAY BE ABSORBED! Redness, skin burns.
    		Protective gloves.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention if irritation or pain persists.
  • 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
    		• Diarrhoea, nausea, vomiting.

    		Rinse mouth. Give water or milk to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Ventilation. 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.
    		Separated from strong oxidants.

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing acrid smoke and fumes. Reacts with strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 50 ppm; 266 mg/m3 (as TWA) (skin) (ACGIH 1991-1992).
    MAK not established.
    OSHA PEL: none
    NIOSH REL: TWA 50 ppm (270 mg/m3) skin
    NIOSH IDLH: No data


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation and through the skin and by ingestion.

    INHALATION RISK:
     A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin and the respiratory tract. Exposure to the vapour could cause depression of the central nervous system.

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