ETHANE	ICSC: 0266 (April 2006)

CAS #: 74-84-0

UN #: 1035

EC Number: 200-814-8

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Extremely flammable. Gas/air mixtures are explosive.	NO open flames, NO sparks and NO smoking. 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.	Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray, powder. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Suffocation. See Notes.	Use ventilation, local exhaust or breathing protection.	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.	Wear face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid.	According to UN GHS Criteria DANGER Extremely flammable gas Contains gas under pressure; may explode if heated Transportation UN Classification UN Hazard Class: 2.1
STORAGE
Fireproof. Cool. Separated from strong oxidants and halogens.

PHYSICAL & CHEMICAL INFORMATION
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. Chemical dangers Reacts violently with halogens and strong oxidants. This increases fire and explosion hazard.	Formula: C₂H₆ / CH₃CH₃ Molecular mass: 30.1 Boiling point: -89°C Melting point: -183°C Solubility in water, ml/100ml at 20°C: (very poor) Vapour pressure, kPa at 20°C: 3850 Relative vapour density (air = 1): 1.05 Flash point: Flammable gas Auto-ignition temperature: 472°C Explosive limits, vol% in air: 3.0-12.5 Octanol/water partition coefficient as log Pow: 1.81

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure Rapid evaporation of the liquid may cause frostbite.	Inhalation risk On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

Effects of short-term exposure
Rapid evaporation of the liquid may cause frostbite.

Inhalation risk
On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT

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. Other UN number : 1961 (refrigerated liquid), Hazard class : 2.1.
