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, powder. 
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 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.

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid.   
EC Classification

flam;flamecylinder;gas

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-20S1035.
NFPA Code: H1; F4; R0. 
Fireproof. Cool. Separated from strong oxidants and halogens. 

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. 

Chemical dangers
Reacts violently with halogens and strong oxidants. This increases fire and explosion hazard. 

Occupational exposure limits
 

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

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

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

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
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  
 

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.
Card has been partially updated in July 2007: see Occupational Exposure Limits, GHS classification.
