Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
NO contact with oxidants,combustibles,reducing agents.
|
Powder, alcohol-resistant foam, water spray, carbon dioxide.
|
|
Explosion
|
Vapour/air mixtures are explosive.
Risk of fire and explosionon contact withcombustible substances.
|
Do NOT expose to friction or shock.
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Use non-sparking handtools.
|
In case of fire: keep drums, etc., cool by spraying with water.
Combat fire from a sheltered position.

Important Data
|
Physical State; Appearance:
COLOURLESS
TO YELLOW
LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
Heating may cause violent combustion or explosion.
May decompose explosively on shock, friction, or concussion.
The substance decomposes
on burning
producing
nitrogen oxides
.
The substance is a strong oxidant and reacts violently with combustible and reducing materials.
Reacts violently with strong oxidants.
Occupational Exposure Limits:
TLV: 25 ppm as TWA; 40 ppm as STEL; BEI issued; (ACGIH 2004).
MAK: 25 ppm, 110 mg/m3
Peak limitation category: II(2);
(DFG 2003).
OSHA PEL: TWA 25 ppm (110 mg/m3)
NIOSH REL: TWA 25 ppm (105 mg/m3) ST 40 ppm (170 mg/m3)
NIOSH IDLH: 500 ppm See: 627134
|
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 respiratory tract
,
the eyes
and
the skin
.
Inhalation of high concentrations of
the substance may cause effects on the
blood
, resulting in
the formation of methaemoglobin.
The effects may be delayed.
Medical observation is indicated.
See Notes.

|
|
N O T E S
|
Combustion in a confined space may turn into detonation.
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
