Xenon appears as a colorless odorless gas. Noncombustible. Heavier than air. May asphyxiate by the displacement of air. Under prolonged exposure to fire or heat containers may rupture violently and rocket.

-112 °C

-108 °C

Solubility in water, g/100ml at 20°C: 0.6 (very poor)

Relative vapour density (air = 1): 4.5

No rapid reaction with air. No rapid reaction with water.

Not Chemically Reactive

These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions. These materials may be nontoxic. They can asphyxiate.

The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.

Excerpt from ERG Guide 121 [Gases - Inert]: Non-flammable gases. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)|Not combustible. Heating will cause rise in pressure with risk of bursting.

|Warning|H280 (73.72%): Contains gas under pressure; may explode if heated [Warning Gases under pressure]|P282, P315, P336, P403, and P410+P403|Aggregated GHS information provided by 353 companies from 5 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.

Excerpt from ERG Guide 121 [Gases - Inert]: Use extinguishing agent suitable for type of surrounding fire. Move containers from fire area if you can do it without risk. Damaged cylinders should be handled only by specialists. FIRE INVOLVING TANKS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)|In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water.

Excerpt from ERG Guide 121 [Gases - Inert]: As an immediate precautionary measure, isolate spill or leak area for at least 100 meters (330 feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 121 [Gases - Inert]: Do not touch or walk through spilled material. Stop leak if you can do it without risk. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. Do not direct water at spill or source of leak. If possible, turn leaking containers so that gas escapes rather than liquid. Prevent entry into waterways, sewers, basements or confined areas. Allow substance to evaporate. Ventilate the area. (ERG, 2016)

Excerpt from ERG Guide 121 [Gases - Inert]: Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing will only provide limited protection. (ERG, 2016)

Personal protection: self-contained breathing apparatus. Ventilation.

Fireproof if in building. Keep in a well-ventilated room.

On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.

Asphyxiation. The liquid may cause frostbite.

Use ventilation.

Cold-insulating gloves. Protective clothing.

Wear safety goggles or face shield.

Gases or volatile liquids that vary in the rate at which they induce anesthesia; potency; the degree of circulation, respiratory, or neuromuscular depression they produce; and analgesic effects. Inhalation anesthetics have advantages over intravenous agents in that the depth of anesthesia can be changed rapidly by altering the inhaled concentration. Because of their rapid elimination, any postoperative respiratory depression is of relatively short duration. (From AMA Drug Evaluations Annual, 1994, p173) (See all compounds classified as Anesthetics, Inhalation.)

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 121 [Gases - Inert]: Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Keep victim calm and warm. (ERG, 2016)

Fresh air, rest. Artificial respiration may be needed. Seek medical attention if you feel unwell.

ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .

Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention.
