EXPOSURE


  • INHALATION

    		• Ventilation.
    		Fresh air, rest.
  • SKIN

    		• Protective gloves.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES

    		• Safety goggles,
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Diarrhoea. Nausea.
    		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 and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in vermiculite, sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS TO YELLOW VISCOUS LIQUID

    PHYSICAL DANGERS:
     As a result of flow, agitation, etc., electrostatic charges can be generated.

    CHEMICAL DANGERS:
     The substance decomposes on burning producing toxic and irritating fumes (phthalic anhydride, ICSC # 0315).

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as TWA): ppm; 5 mg/m3 (ACGIH 1992-1993)
    MAK not established (1992)
    OSHA PEL: TWA 5 mg/m3
    NIOSH REL: TWA 5 mg/m3
    NIOSH IDLH: 4000 mg/m3


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation 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:
