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 water spray, foam, carbon dioxide, powder. 
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.  Avoid inhalation of dust.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion Abdominal pain. Diarrhoea.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered non-metallic containers. Carefully collect remainder. Then store and dispose of according to local regulations.   
EC Classification
 
UN Classification
 
GHS Classification
Signal: Warning
May be harmful if swallowed
Causes eye irritation 

EMERGENCY RESPONSE SAFE STORAGE
  Separated from strong oxidants, metals and food and feedstuffs. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS OR WHITE POWDER. 

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

Chemical dangers
Decomposes on heating. This produces toxic fumes of nitrous oxides. Reacts with strong oxidants. Attacks some forms of metals and rubber. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (2b (not established but data is available)): (DFG 2009). 

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

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly. 

Effects of short-term exposure
The substance is irritating to the eyes. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
