violently with
water
.
Attacks many metals in presence of water.
Occupational Exposure Limits:
TLV not established.
MAK not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is corrosive to
the eyes,
the skin
and
the respiratory tract.
Inhalation of the vapour may cause lung oedema (see Notes).

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 is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do NOT take working clothes home.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
