Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
The vapour mixes well with air, explosive mixtures are easily formed.
Chemical Dangers:
Reacts violently with oxidants.
Attacks many alkaline and earth alkaline metals forming flammable/explosive gas (hydrogen - see ICSC 0001.
Occupational Exposure Limits:
TLV not established.
MAK: 20 ppm, 73 mg/m3
Peak limitation category: I(4); Pregnancy risk group: C
(DFG 2007).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour or aerosol,
through the skin
and
by ingestion.
Inhalation Risk:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
The substance may cause effects on the
central nervous system
, resulting in depression.
Exposure at very high concentrations may result in unconsciousness.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
