|
Routes of Exposure:
The substance can be absorbed into the body by inhalation of its aerosol
Inhalation Risk:
A harmful concentration of airborne particles can be reached quicklywhen dispersed
Effects of Short-Term Exposure:
The substance
is irritating to the skin
.
The substance may cause effects on the blood
, resulting in the formation of methaemoglobin.
Inhalation may cause lung oedema (see Notes).
Effects of Long-Term or Repeated Exposure:

|
Physical
Properties
|
Decomposes below boiling point at 57°C
Melting point (decomposes): 57°C
|
Relative density (water = 1): 1.9
Solubility in water, g/100 ml: (good)
|
|
Environmental
Data
|
The substance is very toxic to aquatic organisms.
It is strongly advised that this substance does not enter the environment.
|
|
N O T E S
|
Depending on the degree of exposure, periodic medical examination is suggested.
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 is therefore essential.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
