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

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.

PHYSICAL PROPERTIES
Boiling point: 1100C
Melting point: 649C
Relative density (water = 1): 1.74
Solubility in water: reaction
ENVIRONMENTAL DATA

NOTES
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.
