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 oxidizing agents.
|
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).
|
In case of fire: keep drums, etc., cool by spraying with water.
|
|
|
|
Exposure
|
|
PREVENT GENERATION OF MISTS!
|
|
|
•Inhalation
|

|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest.
Refer for medical attention.
|
|
•Skin
|
Redness.
|
Protective gloves.

Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH PUNGENT 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 decomposes
on heating and
on burning
producing toxic and irritating fumes (sulfur oxides).
Reacts violently with oxidizing materials, including fuming nitric acid.
Occupational Exposure Limits:
TLV not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour.
Inhalation Risk:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
irritates
the eyes and
the skin.
Effects of Long-Term or Repeated Exposure:
