FIRE Combustible.
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.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


  • INHALATION
  • Cough.
    Local exhaust or breathing protection.
    Fresh air, rest.
  • SKIN
  • Redness.
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
  • Redness.
    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. Wash hands before eating.
    Rinse mouth.
    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: P2 filter respirator for harmful particles).
    Separated from strong oxidants.

    PHYSICAL STATE; APPEARANCE:
    WHITE CRYSTALLINE POWDER.

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

    CHEMICAL DANGERS:
    Reacts violently with strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


    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 when dispersed.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes and the skin.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
