Most important symptoms/effects, acute and delayed

Excerpt from ERG Guide 122 [Gases - Oxidizing (Including Refrigerated Liquids)]: Vapors may cause dizziness or asphyxiation without warning. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases. (ERG, 2016)

Inhalation of 100% oxygen can cause nausea, dizziness, irritation of lungs, pulmonary edema, pneumonia, and collapse. Liquid may cause frostbite of eyes and skin. (USCG, 1999)

Excerpt from ERG Guide 122 [Gases - Oxidizing (Including Refrigerated Liquids)]: Vapors may cause dizziness or asphyxiation without warning. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases. (ERG, 2016)

Indication of immediate medical attention and special treatment needed, if necessary

Some protection against oxygen toxicity syndrome is offered by admin of gamma-aminobutyric acid, succinate, chelating agents, certain anesthetics, and trimethamine (tris-(hydroxymethyl)aminomethane).

SECTION 5: Firefighting measures

Suitable extinguishing media

LIQ: When fire results from a leak or flow of liq oxygen onto wood, paper, waste or another similar material, the first thing to do is stop flow if possible. For small spills, or after leak or flow of liq oxygen has been stopped, use enough water to put out fire quickly. When fire involves liq oxygen and liq fuels, control it as follows: (a) When liq oxygen leaks or flows into large quantities of fuel, shut off flow of liq oxygen, and put remaining fuel fire out with extinguishing agents suitable for use on class B fires. When fuel leaks or flows into large quantities of liq oxygen, shut off flow of fuel. (b) When fuel and liq oxygen are mixed or mixing but are not yet burning, isolate area from sources of ignition and get out quickly, allowing oxygen to evaporate. When large pools of water-soluble fuel are present, use water to dilute fuel and reduce intensity of fire. This method cannot be used with fuels which do not mix with water. Appropriate extinguishing agents may be used to put out fuel fires after the oxygen has evaporated.

Specific hazards arising from the chemical

Excerpt from ERG Guide 122 [Gases - Oxidizing (Including Refrigerated Liquids)]: Substance does not burn but will support combustion. Some may react explosively with fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Vapors from liquefied gas are initially heavier than air and spread along ground. Runoff may create fire or explosion hazard. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)

Behavior in Fire: Increases intensity of any fire. Mixtures of liquid oxygen and any fuel are highly explosive. (USCG, 1999)

Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)

Special protective actions for fire-fighters

SECTION 10: Stability and reactivity

Reactivity

The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard.

Chemical stability

no data available

Possibility of hazardous reactions

Gas: moderate fire risk as oxidizing agent.The gas is heavier than air.,The gas is heavier than air.Oxygen, which is a major component of air, is a propellant; ignites upon contact with alcohols, amines, ammonia, beryllium alkyls, boranes, dicyanogen, hydrazines, hydrocarbons, hydrogen, nitroalkanes, powdered metals, silanes, or thiols [Bretherick 1979. p.174]. Heat of water will vigorously vaporize liquid oxygen, pressures may build to dangerous levels if this occurs in a closed container. Liquid oxygen gives a detonable mixture when combined with powdered aluminum [NFPA 491M. 1991]. Almost any reducing agent and all hydrocarbons can form explosive mixtures with liquid air [Chem. Eng. News 27:2612. 1949]. Explosions have occurred when liquid air contacts organic matter. A cracked tube of activated charcoal immersed in liquid air exploded violently [J. Sci. Inst. 5:24. 1928]. Allyldimethylarsine ignites in air and on filter paper [NFPA 491M. 1991].
