EXPLOSION      
 
EXPOSURE   STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Headache. Nausea. Vomiting. Muscular weakness. Symptoms may be delayed. See Notes.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   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). 
Ingestion Abdominal pain. Nausea. Vomiting. Further see Inhalation.  Do not eat, drink, or smoke during work.  Give a slurry of activated charcoal in water to drink. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including phosphorus oxides. Reacts with oxidants. 

Occupational exposure limits
TLV: 0.1mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued; (ACGIH 2006). 

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

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance may cause effects on the central nervous system and peripheral nervous system. Exposure above the OEL could cause degeneration of the nervous system. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the nervous system.
