|
FIRE
|
Highly flammable.
Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
NO contact with oxidants.
|
Powder, alcohol-resistant foam, water spray, carbon dioxide.
|
|
Explosion
|
Vapour/air mixtures explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Do NOT use compressed air for filling, discharging, or handling.
|
In case of fire: keep drums, etc., cool by spraying with water.

Important Data
|
Physical State; Appearance:
CLEAR COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour mixes well with air, explosive mixtures are easily formed.
Chemical Dangers:
Reacts
with
strong oxidants
causing fire and explosion hazard.
Attacks some forms of plastic and rubber.
Occupational Exposure Limits:
TLV: 200 ppm as TWA, 400 ppm as STEL; A3 (confirmed animal carcinogen with unknown relevance to humans); Intended change (ACGIH 2005).
MAK not established.
OSHA PEL: TWA 200 ppm (500 mg/m3)
NIOSH REL: TWA 200 ppm (500 mg/m3) ST 250 ppm (625 mg/m3) skin
NIOSH IDLH: 800 ppm See: 71238
|
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
irritates
the eyes
.
The substance may cause effects on the central nervous system.
Exposure at high levels may result in unconsciousness.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
