Description of first aid measures
If inhaledFresh air, rest. Artificial respiration may be needed. Refer for medical attention.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms and effects, both acute and delayed
Excerpt from ERG Guide 121 [Gases - Inert]: Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. (ERG, 2016)
Excerpt from ERG Guide 120 [Gases - Inert (Including Refrigerated Liquids)]: Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. (ERG, 2016)
Indication of any immediate medical attention and special treatment needed
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Simple asphyxiants and related compounds
Extinguishing media
If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. Material itself does not burn or burns with difficulty. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Argon, compressed; Argon, refrigerated liquid
Specific Hazards Arising from the Chemical
Excerpt from ERG Guide 121 [Gases - Inert]: Non-flammable gases. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)
Excerpt from ERG Guide 120 [Gases - Inert (Including Refrigerated Liquids)]: Non-flammable gases. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)
Advice for firefighters
In case of fire in the surroundings, use appropriate extinguishing media.
NFPA 704
| HEALTH | 3 | Short exposure could cause serious temporary or moderate residual injury (e.g. liquid hydrogen, sulfuric acid, calcium hypochlorite, hexafluorosilicic acid) | |
| FIRE | 0 | Materials that will not burn under typical fire conditions, including intrinsically noncombustible materials such as concrete, stone, and sand. Materials that will not burn in air when exposed to a temperature of 820 °C (1,500 °F) for a period of 5 minutes.(e.g. Carbon tetrachloride) | |
| REACT | 0 | Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2) | |

Personal precautions, protective equipment and emergency procedures
Personal protection: self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid.
Environmental precautions
Personal protection: self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid.
Methods and materials for containment and cleaning up
Personal precautions: Avoid breathing vapors, mist or gas. Environmental precautions: No special environmental precautions required. Methods for cleaning up: Wipe up with absorbent material (e.g. cloth, fleece).
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof if in building. Keep in a well-ventilated room.Keep container tightly closed in a dry and well-ventilated place. Contents under pressure.

Possibility of hazardous reactions
The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.These substances undergo no chemical reactions under any known circumstances. They are nonflammable, noncombustible and nontoxic. They can asphyxiate.
Conditions to avoid
no data available
Incompatible materials
CHEMICAL PROFILE: Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container (Handling Chemicals Safely 1980). (REACTIVITY, 1999)
