FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

EXPOSURE		AVOID ALL CONTACT!
Inhalation	Burning sensation. Cough. Shortness of breath. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Refer for medical attention.
Skin	Skin burns. Pain. Blisters.	Protective clothing.	Rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
Eyes	Redness. Pain. Severe deep burns.	Face shield or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Burning sensation. Shock or collapse.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest. Refer for medical attention.

TRISODIUM PHOSPHATE (ANHYDROUS)

ICSC: 1178

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including phosphorous oxides. The solution in water is a strong base, it reacts violently with acid and is corrosive. Attacks many metals in presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of dust may cause lung oedema (see Notes).

PHYSICAL PROPERTIES

Melting point (decomposes): 75°C
Relative density (water = 1): 2.5
Solubility in water, g/100 ml: 8.8

ENVIRONMENTAL DATA

NOTES

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
