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.
 
EXPOSURE


INHALATION Drowsiness. Unconsciousness.
Ventilation.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
SKIN


EYES


INGESTION


SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Evacuate danger area! Ventilation. Eliminate ignition sources and turn off gas at source if possible (extra personal protection: chemical suit with self-contained breathing apparatus).
Fireproof. Separated from strong oxidants.

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 (OELs):
TLV: ppm; mg/m3 (a simple ashyxiant) (ACGIH 1995-1996).


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 may result in lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
 Boiling point: -104°C
Melting point: -169.2°C
Solubility in water: none
Vapour pressure, kPa at 15°C: 8100		 Relative vapour density (air = 1): 0.98
Flash point: flammable gas
Auto-ignition temperature: 490°C
Explosive limits, vol% in air: 2.7-36.0
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.
