First Aid/
Fire Fighting
|
|
FIRE
|
Extremely flammable.
|
NO open flames, NO sparks, and NO smoking.
NO contact with hot surfaces.
|
Alcohol-resistant foam.
Powder.
Carbon dioxide.
|
|
Explosion
|
Vapour/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Prevent build-up of electrostatic charges (e.g., by grounding).
Do NOT use compressed air for filling, discharging, or handling.
Use non-sparking handtools.
|
In case of fire: keep drums, etc., cool by spraying with water.

Important Data
|
Physical State; Appearance:
VERY VOLATILE, COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
The substance can form explosive peroxides under the influence of light and air.
Reacts
violently with
halogens
,
interhalogens, sulfur compounds and
oxidants
causing fire and explosion hazard.
Attacks plastic and rubber.
Occupational Exposure Limits:
TLV: 400 ppm as TWA; 500 ppm as STEL; (ACGIH 2001).
EU OEL: 100 ppm, 308 mg/m3 as TWA; 200 ppm, 616 mg/m3 as STEL (EU 2000).
OSHA PEL: TWA 400 ppm (1200 mg/m3)
NIOSH REL: See Appendix D
NIOSH IDLH: 1900 ppm 10%LEL See: 60297
|
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 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
.
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
The substance may cause effects on the
central nervous system
, resulting in narcosis.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
The substance may have effects on the
central nervous system
.
Caution, may cause addiction.
