  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion when exposed to heat or flame. Explosive.  NO open flames, NO sparks and NO smoking. NO contact with hot surfaces.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT expose to friction or shock. Prevent deposition of dust.  Do not attempt to extinguish large fire, evacuate area.  In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. 

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Abdominal pain. Cough. Diarrhoea. Headache. Sore throat. Nosebleeds.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Yellow staining of the skin.  Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Wear protective gloves when administering first aid. 
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 Nausea. See Inhalation.  Do not eat, drink, or smoke during work.  Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
ODOURLESS COLOURLESS-TO-YELLOW CRYSTALS. 

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

Chemical dangers
May decompose explosively on shock, friction or concussion. Decomposes explosively on heating to 187°C. Reacts with some oxidants. This generates fire and explosion hazard.

Molecular mass: 287.15
Melting point: 130°C
Relative density (water = 1): 1.57
Solubility in water: none
Vapour pressure, kPa at 20°C: <0.1

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. The substance may have effects on the liver, kidneys and blood. 


Occupational exposure limits
TLV: 1.5 mg/m3, ppm, as TWA.
MAK: skin absorption (H); sensitization of skin (SH); carcinogen category: 3B
