	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Highly flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with acids, halogens or water.	NO contact with water, acids or halogens. NO open flames, NO sparks and NO smoking.	Use special powder, dry sand. NO other agents. Combat fire from a sheltered position.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Burning sensation.	Use closed system or ventilation.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance SILVERY SOLID IN VARIOUS FORMS. Physical dangers Chemical dangers Reacts violently with water. This generates fire and explosion hazard. Decomposes rapidly under the influence of air and moisture. This produces flammable/explosive gas (hydrogen - see ICSC 0001).	Formula: Na Atomic mass: 23.0 Boiling point: 880°C Melting point: 97.4°C Density: 0.97 g/cm³ Solubility in water: reaction Vapour pressure at 20°C: negligible Auto-ignition temperature: 120-125°C
