PHYSICAL STATE; APPEARANCE:
COLOURLESS, HYGROSCOPIC CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating (924°C), producing toxic fumes. The solution in water is a strong base, it reacts violently with acid and is corrosive to aluminium and zinc. Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol 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 the substance may cause lung oedema (see Notes). Exposure may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point (decomposes): 924°C
Melting point: 450-471°C
Density: 1.51
g/cm3
Solubility in water, g/100 ml at 20°C: 10.9

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to water organisms.

N O T E S

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.
Transport Emergency Card: TEC (R)-751
