  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

flam;flamecylinder;gas
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. 
PACKAGING
 
ETHANE ICSC: 0266
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.

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.
