TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Many reactions may cause fire or explosion. See Chemical dangers  NO open flames. See Chemical Dangers.  NO hydrous agents, foam, carbon dioxide. Use inert gas, dry sand, special powder. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Burning sensation. Nausea. Vomiting. Shortness of breath.  Use closed system or breathing protection.  Fresh air, rest. Half-upright position. No mouth-to-mouth artificial respiration. Refer immediately for medical attention. 
Skin Redness. Pain. Blisters. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Put clothes in sealable container. Rinse skin with plenty of water or shower. Refer immediately for medical attention . 
Eyes Redness. Pain. Blurred vision. Severe deep burns.  Wear face shield or eye protection in combination with breathing protection if powder.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Sore throat. Nausea. Abdominal pain. Burning sensation. Vomiting. Diarrhoea. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

NFPA Code: H3; F2; R2; W.  Separated from incompatible materials. See Chemical Dangers. Dry. Keep under mineral oil or inert gas. Cool. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
ODOURLESS WHITE-TO-GREYISH HYGROSCOPIC SOLID IN VARIOUS FORMS. TURNS DARK ON EXPOSURE TO LIGHT. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces irritating alkali fumes. The substance may ignite spontaneously on contact with moist air. The substance is a strong reducing agent. Reacts violently with oxidants, halogenated hydrocarbons and acids. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Reacts violently with water. This produces corrosive fumes of lithium hydroxide. 

Occupational exposure limits
TLV: 0.025mg/m³ as TWA; (ACGIH 2014). 

Routes of exposure
Serious local effects by all routes of exposure. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause severe swelling of the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. See Notes. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 850°C
Melting point: 680°C
Density: 0.8 g/cm³

NOTES
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
Do NOT take working clothes home.
Reacts violently with fire extinguishing agents such as water, carbon dioxide and foam.
