|
Acute Hazards/ Symptoms
|
Prevention
|
First Aid/
Fire Fighting
|
|
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 are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Prevent build-up of electrostatic charges (e.g., by grounding).
|
In case of fire: keep drums, etc., cool by spraying with water.

Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may travel along the ground; distant ignition possible.
Chemical Dangers:
The substance decomposes
on heating
producing toxic fumes of nitrogen oxides.
The substance is a strong base, it reacts violently with acid and is corrosive to copper and zinc and their alloys, aluminium and galvanized steel.
Reacts
violently with
oxidants
causing fire and explosion hazard.
Attacks some forms of plastics.
Occupational Exposure Limits:
TLV: 5 ppm as TWA; (skin); (ACGIH 2004).
OSHA PEL: TWA 5 ppm (20 mg/m3) skin
NIOSH REL: TWA 5 ppm (20 mg/m3) skin
NIOSH IDLH: 200 ppm See: 108189
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour,
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
Tear drawing.
The vapour
is corrosive to
the eyes
and
the respiratory tract.
Inhalation of the vapour may cause lung oedema (see Notes).
Contact of the eyes with the vapour or liquid may induce visual disturbances.
Exposure may result in death.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.

N O T E S
|
Other reported melting points: -91°C and -96°C.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
