TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water in large amounts, powder, carbon dioxide. 
EXPLOSION Risk of explosion. Explosive.  Do NOT expose to friction or shock. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Combat fire from a sheltered position. In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Weakness. Dizziness. Headache. Nausea. Convulsions. Unconciousness.  Use closed system or ventilation.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Do NOT induce vomiting. Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention.

Physical dangers
 

Chemical dangers
May decompose explosively on shock, friction or concussion. May explode on heating. This produces nitrogen oxides. Reacts with strong oxidants and combustible substances. 

Occupational exposure limits
TLV: 0.5mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); (ACGIH 2006). 

Routes of exposure
The substance can be absorbed into the body in hazardous amounts by inhalation and by ingestion. 

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

Effects of short-term exposure
The substance may cause effects on the central nervous system. This may result in irritability, insomnia, convulsions and unconsciousness. 

Effects of long-term or repeated exposure
The substance may have effects on the central nervous system. Repeated or prolonged contact with skin may cause dermatitis.
