TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking. NO contact with moisture, acids, halogens and many other substances.
Special powder, dry sand, NO other agents. NO water.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Do NOT expose to friction or shock. Prevent build-up of electrostatic charges (e.g., by grounding).

EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION Cough. Laboured breathing. Headache. Dullness. Weakness. Fever or elevated body temperature.


 •SKIN


 •EYES Redness. Pain.
Safety goggles.

 •INGESTION Abdominal pain. Diarrhoea.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for harmful particles.
Fireproof. Separated from strong oxidants, acids. Dry.

PHYSICAL STATE; APPEARANCE:
GREY 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 may spontaneously ignite on contact with air or moisture producing irritating or toxic fumes . Reacts violently with strong oxidants. Reacts violently with many substances causing fire and explosion hazard. Reacts with acids and water forming flammable/explosive gas (hydrogen - see ICSC0001) , causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
Inhalation of fumes may cause metal fume fever.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

DATA

N O T E S
Burns with an intense flame. In order to prevent eye injury do not look directly at magnesium fires. Reacts violently with fire extinguishing agents such as water, carbon dioxide and powder. Explosive limits, vol% in air: (LEL) 0.03 kg/m. Card has been partly updated in October 2005. See section Emergency Response.
