TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances.  NO contact with flammables.  In case of fire in the surroundings, use appropriate extinguishing media. NO carbon dioxide. 
EXPLOSION Risk of fire and explosion on contact with combustible substances or reducing agents.     
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Cough. Shortness of breath. Sore throat. See Ingestion.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 
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 Excessive salivation. Abdominal cramps. Abdominal pain. Diarrhoea. Nausea. Vomiting. Shortness of breath. Weakness.  Do not eat, drink, or smoke during work.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). See Notes. Refer for medical attention .

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

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces nitrogen oxides. The substance is a strong oxidant. It reacts with combustible and reducing materials. Reacts with powdered metals. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 0.5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK (inhalable fraction): 0.5 mg/m³; Peak limitation category: II(2); (DFG 2003). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Exposure could cause hypokalaemia. This may result in cardiac disorders and muscular disorders. Exposure could cause death. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes
Melting point: 590°C
Density: 3.24 g/cm³
Solubility in water, g/100ml at 20°C: 8.7  
The substance is harmful to aquatic organisms. 

NOTES
Temperature of decomposition unknown in literature.
Rinse contaminated clothes (fire hazard) with plenty of water.
Will turn shock-sensitive if contaminated with magnesium-aluminium alloys, sulfur powder or light metal powder.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
