Important Data
|
Physical State; Appearance:
WHITE CRYSTALLINE POWDER.
Physical Dangers:
Chemical Dangers:
The solution in water is a medium strong acid.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation or
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly by dispersing.
Effects of Short-Term Exposure:
Corrosive.
The substance
is corrosive to
the eyes,
the skin and
the respiratory tract.
Corrosive on ingestion.
Inhalation of aerosol may cause lung oedema (see Notes).
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:

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.
