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.
|
Powder, AFFF, foam, 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.
|
In case of fire: keep drums, etc., cool by spraying with water.
|
|
|
|
Exposure
|
|
|
|
|
•Inhalation
|
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest.
|
|
•Skin
|
|
Protective gloves.
|
Remove contaminated clothes.
Rinse and then wash skin with water and soap.
|
|
•Eyes

Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID.
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 burning
producing
toxic and corrosive fumes
including
hydrogen chloride
(see ICSC 0163)
and
phosgene
(see ICSC 0007).
Reacts
violently with
strong oxidants
and
powdered metals
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV not established.
|
