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 powder,carbon dioxide.
|
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 |
Drowsiness.Unconsciousness.
|
Closed system and 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.

IMPORTANT DATA |
PHYSICAL STATE;APPEARANCE: ODOURLESS,COLOURLESS COMPRESSED LIQUEFIED GAS.
PHYSICAL DANGERS: The gas is heavier than air and may travel along the ground;distant ignition possible,and may accumulate in low ceiling spaces causing deficiency of oxygen.As a result of flow,agitation,etc.,electrostatic charges can be generated.
OCCUPATIONAL EXPOSURE LIMITS: TLV: (Aliphatic hydrocarbon gases) 1000 ppm as TWA;(ACGIH 2005). MAK: 1000 ppm,1800 mg/m3;Peak limitation category: II(4);Pregnancy risk group: D;(DFG 2006).
|
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.The substance may cause effects on the central nervous system.

PHYSICAL PROPERTIES |
Boiling point: -42℃ Melting point: -189.7℃ Relative density (water = 1): 0.5 Solubility in water,g/100 ml at 20℃: 0.007 Vapour pressure,kPa at 20℃: 840 Relative vapour density (air = 1): 1.6
|
Flash point: -104℃ Auto-ignition temperature: 450℃ Explosive limits,vol% in air: 2.1-9.5 Octanol/water partition coefficient as log Pow: 2.36
|
ENVIRONMENTAL DATA |
|
NOTES |
Check oxygen content before entering area.Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.Card has been partially updated in July 2007: see Occupational Exposure Limits.
