Acute Hazards/ Symptoms
|
Prevention
|
First Aid/
Fire Fighting
|
|
FIRE
|
Extremely flammable.
|
NO open flames, NO sparks, and NO smoking.
|
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with
water spray.
|
|
Explosion
|
Gas/air mixtures are explosive.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Prevent build-up of electrostatic charges (e.g., by grounding).
Use non-sparking handtools.
|
In case of fire: keep cylinder cool by spraying with water.
Combat fire from a sheltered position.

Important Data
|
Physical State; Appearance:
COLOURLESS
COMPRESSED GAS
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The gas is lighter than air.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
The substance may polymerize to form aromatic compounds
under the influence of temperatures above 600°C.
Reacts
with
strong oxidants
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: 200 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2005).
MAK:
Carcinogen category: 3B;
(DFG 2005).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.
Effects of Short-Term Exposure:
Exposure could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
|
|

none
Vapour pressure, kPa at 15°C: 8100
|
Relative vapour density (air = 1): 0.98

Environmental
Data
|
|
|
N O T E S
|
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
