First Aid/
Fire Fighting
|
|
FIRE
|
Highly flammable.
|

Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour mixes well with air, explosive mixtures are formed easily.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
Reacts
violently with
strong oxidants
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 50 ppm as TWA; (skin); A4; BEI issued; (ACGIH 2004).
MAK:
Pregnancy risk group: C;
(DFG 2004).
EU OEL: 192 mg/m3 50 ppm as TWA 384 mg/m3 100 ppm as STEL (skin) (EU 2006).
OSHA PEL: TWA 200 ppm C 300 ppm 500 ppm (10-minute maximum peak)
NIOSH REL: TWA 100 ppm (375 mg/m3) ST 150 ppm (560 mg/m3)
NIOSH IDLH: 500 ppm See: 108883
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
and
the respiratory tract
.
The substance may cause effects on the
central nervous system
.
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
Exposure at high levels may result in cardiac dysrhythmia and unconsciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
The substance may have effects on the
central nervous system
.
Exposure to the substance may enhance hearing damage caused by exposure to noise.
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
