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.
In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water.Combat fire from a sheltered position.
EXPOSURE


Inhalation Drowsiness.Suffocation (see Notes).
Ventilation.
Fresh air,rest.Artificial respiration if indicated.Refer for medical attention.
Skin ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
ON FROSTBITE: rinse with plenty of water,do NOT remove clothes.Refer for medical attention.
Eyes See Skin.
Safety goggles or face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible),then take to a doctor.
Ingestion
Do not eat,drink,or smoke during work.

SPILLAGE DISPOSAL PACKAGING & LABELLING

IMPORTANT DATA
PHYSICAL STATE;APPEARANCE:
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.

CHEMICAL DANGERS:
Reacts violently with oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: Simple asphyxiant A4 (not classifiable as a human carcinogen);Intended change (ACGIH 2005).
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
On loss of containment this gas 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.The substance may cause effects on the central nervous system.Exposure could cause lowering of consciousness.See Notes.

PHYSICAL PROPERTIES
Boiling point: -48℃
Melting point: -185℃
Relative density (water = 1): 0.5
Solubility in water: poor
Vapour pressure,kPa at 25℃: 1158
Relative vapour density (air = 1): 1.5
Flash point: Flammable Gas
Auto-ignition temperature: 460℃
Explosive limits,vol% in air: 2.4-10.3
Octanol/water partition coefficient as log Pow: 1.77
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 partially updated in August 2007: see Occupational Exposure Limits.
