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   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Burning sensation. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer immediately for medical attention. 
Skin Skin burns. Pain.  Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention . 
Eyes Redness. Pain. Severe deep burns.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.

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

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including phosphorus oxides. The solution in water is a strong base. It reacts violently with acid and is corrosive. Attacks many metals in the presence of water. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
EU OEL ( selected):. 

Routes of exposure
Serious local effects by all routes of exposure. 

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

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 75°C
Relative density (water = 1): 2.5
Solubility in water, g/l at 20°C: 121 (good) 
Environmental effects from the substance have not been investigated adequately.
