EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION

    		• Local exhaust.
    		Fresh air, rest.
  • SKIN

    		• Protective gloves.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES

    		• Safety spectacles.
    		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.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting.
    		Well closed.

    PHYSICAL STATE; APPEARANCE:
     WHITE CRYSTALS OR POWDER , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:
     Dust explosion possible if in powder or granular form, mixed with air.

    CHEMICAL DANGERS:

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as stearates): ppm; 10 mg/m3 (ACGIH 1996).


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

    INHALATION RISK:
     Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly by dispersing aerosols.

    EFFECTS OF SHORT-TERM EXPOSURE:

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point (decomposes): 376°C
    Melting point: 69-72°C
    Relative density (water = 1): 0.94-0.83
    Solubility in water: none
    		 Vapour pressure, Pa at 174°C: 133
    Flash point: 196°C
    Auto-ignition temperature: 395°C
    ENVIRONMENTAL
    DATA
