TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water in large amounts. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation   Use ventilation.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Keep wet. Collect leaking and spilled liquid in covered containers as far as possible. Carefully collect remainder. Then store and dispose of according to local regulations.

IMPORTANT DATA
Physical State; Appearance
WHITE SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
The substance is spontaneously flammable when dry. Decomposes rapidly on burning. This produces nitrogen oxides. This generates fire and explosion hazard. Reacts with oxidants, bases and acids. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

Inhalation risk
 

Effects of short-term exposure
See Notes. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Relative density (water = 1): 1.66
Solubility in water: none 
 

NOTES
The commercial products are formulated with 30-35% of water, or ethanol, or 1-butanol or Isopropanol.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvents also consult the ICSCs of these materials.
The formulation with more than 12.6% nitrogen is used exclusively for the explosives; EU classification: Index number 603-037-00-6, symbol E, R:1-3, S:(2-)35.
