TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use foam, dry powder, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.   
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough.  Use ventilation (not if powder).  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.  Do not transport with food and feedstuffs. 
EC Classification
 
UN Classification
UN Hazard Class: 6.1; UN Pack Group: II

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-61s1578.  Separated from bases, strong oxidants and food and feedstuffs. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive fumes of nitrogen oxides and hydrogen chloride (see ICSC 0163). Reacts with strong oxidants and bases. 

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

Routes of exposure
The substance can be absorbed into the body by ingestion. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.
