TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Highly flammable when finely divided. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking. NO contact with water or any other substances.  Use dry sand, special powder. NO hydrous agents, carbon dioxide, other agents. 
EXPLOSION See Notes.     
 
EXPOSURE      
Inhalation See Notes.    Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion Burning sensation in the mouth and in the chest and stomach.  Do not eat, drink, or smoke during work.  Rinse mouth. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT wash away into sewer. Sweep spilled substance into covered dry containers. Carefully collect remainder. Then store and dispose of according to local regulations.  Airtight.

IMPORTANT DATA
Physical State; Appearance
SILVERY-WHITE METALLIC SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
Reacts with water. This produces flammable/explosive gas (hydrogen - see ICSC 0001). This generates fire and explosion hazard. Contact with many other substances may cause dangerous reactions. Decomposes on heating. This produces toxic and irritating fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (not established):. 

Routes of exposure
 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 1100°C
Melting point: 649°C
Density: 1.7 g/cm³
Solubility in water: reaction 
 

NOTES
Burns with an intense flame.
In order to prevent eye injury do not look directly at magnesium fires.
Magnesium powder could be present with pellets. It is strongly recommended to consult the card for magnesium powder.
See ICSC 0289.
Reacts violently with fire extinguishing agents such as water, powder, carbon dioxide, halons and foams.
