FIRE
|
Flammable.
|
NO open flames, NO sparks, and NO smoking.
|
Alcohol-resistant foam,
dry powder,

Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
Reacts with oxidants
,
bases
and
reducing agents
.
Occupational Exposure Limits:
TLV: 50 ppm as TWA (ACGIH 2000).
OSHA PEL: none
NIOSH REL: TWA 50 ppm (235 mg/m3)
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance
is mildly irritating to
the eyes
and
the skin
.
The vapour
is irritating to
the respiratory tract
.
Exposure at high levels may result in lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
