ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable in powder form. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking. NO contact with moisture or acid.
Dry sand. Special powder. NO hydrous agents. NO water.
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
  • Cough.
    Local exhaust or breathing protection.
    Fresh air, rest.
  • SKIN

  • Protective gloves.
    Rinse skin with plenty of water or shower.
  • EYES
  • Redness. Pain.
    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.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into container. Do NOT wash away into sewer. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).
    Fireproof. Separated from strong oxidants, acids, carbonates, halogens. Dry.
    Airtight.

    PHYSICAL STATE; APPEARANCE:
    SILVERY-WHITE METALLIC SOLID IN VARIOUS FORMS.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance may spontaneously ignite on contact with air if finely divided or on heating. Upon heating, toxic fumes are formed. The substance is a strong reducing agent and reacts violently with oxidants and many other substances causing fire and explosion hazards. Reacts with moisture or acids, evolving combustible gas (Hydrogen - see ICSC # 0001), causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


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

    INHALATION RISK:

    DATA

    N O T E S
    Magnesium burns with an intense flame. Avoid direct viewing of magnesium fires. Reacts violently with fire extinguishing agents such as water, powder, carbon dioxide and halons.
