TYPES OF HAZARD / EXPOSURE 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) if in liquid state. Use non-sparking handtools.
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE


Inhalation Simple axphyxiant.
Ventilation.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves. Protective clothing.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
Eyes ON CONTACT WITH LIQUID: FROSTBITE.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion


SPILLAGE DISPOSAL PACKAGING & LABELLING

ETHANE ICSC: 0266
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS COMPRESSED LIQUEFIED GAS, ODOURLESS WHEN PURE.

PHYSICAL DANGERS:
The gas mixes well with air, explosive mixtures are easily formed. As a result of flow, agitation, etc., electrostatic charges can be generated.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: Simple asphyxiant; (ACGIH 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.

EFFECTS OF SHORT-TERM EXPOSURE:
Rapid evaporation of the liquid may cause frostbite.

PHYSICAL PROPERTIES
Boiling point: -89C
Melting point: -183C
Solubility in water, ml/100 ml at 20C: 4.7
Vapour pressure, kPa at 20C: 3850
Relative vapour density (air = 1): 1.05
Flash point: flammable gas
Auto-ignition temperature: 472C
Explosive limits, vol% in air: 3.0-12.5
Octanol/water partition coefficient as log Pow: 1.81
ENVIRONMENTAL DATA

NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
