TYPES OF HAZARD/ EXPOSURE 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

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 hazard. Reacts with moisture or acids, evolving combustible gas (Hydrogen - see ICSC 0001), causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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

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. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
