Safety spectacles
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID

PHYSICAL DANGERS:


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 20C.

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.
