ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION

  • Avoid inhalation of fine dust and mist.
    Fresh air, rest. Refer for medical attention.
  • SKIN


  • 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

  • Do not eat, drink, or smoke during work.
    Rinse mouth. Give plenty of water to drink.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P1 filter respirator for inert particles).

    PHYSICAL STATE; APPEARANCE:
    WHITE, FINE, SOFT POWDER.

    PHYSICAL DANGERS:
    Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc.

    CHEMICAL DANGERS:
    The substance decomposes on heating producing acrid smoke and fumes of zinc oxide.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: ppm; 10 mg/m3 (ACGIH 1992-1993).


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:


    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
