    PHYSICAL STATE; APPEARANCE:
     YELLOW OILY LIQUID.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic fumes. Reacts with strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; mg/m3 A3, skin (ACGIH 1997).
    OSHA PEL: 1910.1016 See Appendix B
    NIOSH REL: Ca See Appendix A
    NIOSH IDLH: Potential occupational carcinogen No data


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

    INHALATION RISK:
     No indication can be given about the rate in which a harmful concentration in the air is 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. The substance may cause effects on the liver , resulting in jaundice. The effects may be delayed. Medical observation is indicated. See Notes.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the liver , resulting in liver function impairment and cirrhosis. This substance is probably carcinogenic to humans.
