ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

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
PREVENT DISPERSION OF DUST!

•INHALATION Cough. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest.
•SKIN Dry skin. Redness.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES

PHYSICAL STATE; APPEARANCE:
ODOURLESS, VERY HYGROSCOPIC COLOURLESS CRYSTALS.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating at high temperature and on burning producing toxic and corrosive fumes. The solution in water is a weak base. Attacks zinc in presence of water forming highly flammable hydrogen gas. Dissolves violently in water with liberation of much heat.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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

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 irritates the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the nasal mucous membrane , resulting in ulcerations.

PHYSICAL
PROPERTIES

Boiling point: 1935°C
Melting point: 772°C
Relative density (water = 1): 2.16
Solubility in water, g/100 ml at 20°C: 74.5
