TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE      
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  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

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-WHITE HYGROSCOPIC CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Decomposes above 160°C . This produces ammonia, nitrogen oxides and sulfur oxides. The solution in water is a weak acid. Attacks mild steel. Contact with hot water may cause formation of large amounts of steam. Reacts with acids and strong oxidants. 

Occupational exposure limits
TLV: 10mg/m³ as TWA; (ACGIH 2004). 

Routes of exposure
 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly on spraying or when dispersed, especially if powdered. 

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

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 160°C
Melting point: 131°C
Relative density (water = 1): 1.8
Solubility in water: very good
Vapour pressure at 20°C: negligible
