TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.     
 
EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.  AVOID ALL CONTACT!   
Inhalation   Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves. Protective clothing.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes above 320°C . This produces hydrogen chloride and phosphorous oxides. Reacts with strong bases and strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body in hazardous amounts by ingestion. 

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
