TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Forms flammable gas on contact with water or damp air. May ignite spontaneously on contact with air.  NO contact with air, water or incompatible substances.  NO water. Use special powder, dry sand. NO other agents. 
EXPLOSION Risk of fire and explosion on contact with water or incompatible substances. See Chemical Dangers.  PREVENT DISPERSION OF DUST. Use non-sparking handtools.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Refer immediately for medical attention. 
Skin Redness. Pain. Serious skin burns.  Protective gloves. Protective clothing.  Rinse contaminated clothes (fire hazard) with plenty of water. Rinse skin with plenty of water or shower. Refer immediately for medical attention. 
Eyes Redness. Pain. Burns.  Wear safety goggles or face shield.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Burning sensation. Abdominal pain. Abdominal cramps. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention. 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
SILVERY-WHITE-TO-GREY POWDER. 

Physical dangers
Ignites in air when finely divided. 

Chemical dangers
The substance is a strong reducing agent. Reacts with moisture, water, alcohols, halogens and many other substances. This produces flammable/explosive gas (hydrogen - see ICSC 0001). 

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

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. 

Effects of short-term exposure
The substance is severely irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
