TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Not combustible. Heating will cause rise in pressure with risk of bursting.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE
Inhalation	Dizziness. Dullness. Headache. Suffocation.	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.	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

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Ventilation. NEVER direct water jet on liquid. (Extra personal protection: self-contained breathing apparatus.)	UN Hazard Class: 2.2

EMERGENCY RESPONSE	STORAGE
Transport Emergency Card: TEC (R)-20S1951	Fireproof if in building. Keep in a well-ventilated room.

IMPORTANT DATA
Physical State; Appearance ODOURLESS, COLOURLESS, LIQUEFIED GAS. Physical dangers The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. Occupational exposure limits TLV: Simple asphyxiant, (ACGIH 2003). 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 Suffocation. The liquid may cause frostbite.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: -185.9°C Melting point: -189.2°C Solubility in water, ml/100 ml at 20°C: 3.4 Relative vapour density (air = 1): 1.66 Octanol/water partition coefficient as log Pow: 0.94

NOTES

Other UN number: 1006 Argon, compressed.
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
