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.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion. Explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT expose to friction or shock.  Combat fire from a sheltered position. 
 
EXPOSURE      
Inhalation See Ingestion.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. 
Skin MAY BE ABSORBED! Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles 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 Confusion. Drowsiness. Convulsions. Unconsciousness.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-10G1.  Fireproof. Separated from strong bases and strong acids. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS. 

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated. Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Heating may cause violent combustion or explosion. May decompose explosively on shock, friction or concussion. Decomposes on heating. This produces toxic gases including nitrogen oxides. Reacts violently with acids and bases. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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

Effects of short-term exposure
The substance is irritating to the eyes and skin. The substance may cause effects on the central nervous system. This may result in irritability, convulsions and lowering of consciousness. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the kidneys and liver.
