  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Forms flammable gas on contact with water or damp air. May ignite spontaneously on contact with air.  Risk of fire and explosion on contact with water or incompatible substances. See Chemical Dangers.  NO contact with air, water or incompatible substances.  PREVENT DISPERSION OF DUST. Use non-sparking handtools.  NO water. Use special powder, dry sand. NO other agents.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 

 PREVENT DISPERSION OF DUST! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
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 CLASSIFICATION & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. Consult an expert! Remove all ignition sources. Cover the spilled material with dry sand or dry powder. Do NOT absorb in saw-dust or other combustible absorbents. Carefully collect remainder. Then store and dispose of according to local regulations.

EXPOSURE & HEALTH EFFECTS

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

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

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


Occupational exposure limits
 

ENVIRONMENT
No data. 

NOTES
Reacts violently with fire extinguishing agents such as water, foam, halons and carbon dioxide.
Do NOT take working clothes home.
Health effects of exposure to the substance have not been investigated adequately.
