PHYSICAL STATE; APPEARANCE:
ODOURLESS HYGROSCOPIC WHITE GRANULES OR POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The solution in water is a medium strong base. Reacts with strong acids.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.
PDK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of dust.

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

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
 Melting point: 1090°C
 Solubility in water: Very good (187 g/100 ml at 25°C)
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.
