ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Burning sensation. Cough. Sore throat.
Local exhaust.
Fresh air, rest. Refer for medical attention.
•SKIN Redness. Burning sensation. Pain. Blisters.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Redness. Pain. Severe deep burns.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS OR AMBER LIQUID.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating at 240°C producing toxic fumes of phosphorous oxides. Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001).

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and through the skin.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes and the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Decomposes below boiling point at 240°C

g/cm3
Solubility in water, g/100 ml at 20°C: 0.21
Vapour pressure, Pa at 20°C: <10
Flash point:
196°C o.c.
Octanol/water partition coefficient as log Pow: 2.67

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.
