IMPORTANT DATA

Physical State; Appearance
COLOURLESS TO YELLOW LIQUID

Chemical dangers
The substance decomposes on heating at temperatures above 320° C producing hydrogen chloride and phosphorus oxides. Reacts with strong bases and strong oxidants.

Occupational exposure limits
TLV not established.
MAK 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 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.
