Important Data
|
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.
