	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible. Heating will cause rise in pressure with risk of bursting.		In case of fire in the surroundings, use appropriate extinguishing media.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Dizziness. Lethargy. Headache. Suffocation.	Use 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.	Wear safety goggles or 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
Personal protection: self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 2.2

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
Asphyxiation. 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
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.
