Oxygen is safe and non-flammable; however, it supports combustion (materials burn more readily in an oxygen-enriched environment), so be careful when on oxygen therapy.

Traveling by air may be a problem for persons using supplemental oxygen. Commercial air carriers' policies regarding in-flight oxygen vary considerably. Most airlines require a letter on your health provider’s letterhead, with his or her name and contact information, your specific underlying lung condition, approval for air travel, and verification of the need for in-flight oxygen. Be aware that airlines do not provide oxygen for ground use, so take enough for layovers and weather delays. Check with the particular airline you intend to fly regarding their specific policy.

There are fewer restrictions when traveling by land; however, you should still talk with your health provider. Let him or her know about the altitudes you'll be traveling to because your flow rate prescription may need to be altered. Do not store oxygen in the trunk of a vehicle where it can get very hot. Because oxygen containers release small amounts of gas periodically, keep a window partially open, regardless of the weather.

Remember these safety tips from the American Lung Association when using supplemental oxygen:

You should never smoke while using oxygen and warn visitors not to smoke near you.

Stay at least 5 feet away from gas stoves, candles, lighted fireplaces, or other heat sources.

If you use an oxygen cylinder, make sure it is secured to some fixed object or in a stand.

If you use liquid oxygen, make sure the vessel is kept upright to keep the oxygen from pouring out; the liquid oxygen is so cold it can hurt your skin.

Keep a fire extinguisher close by and let your fire department know that you have oxygen in your home.
