An oxygen concentrator is an electronic, and as with all electronics, you have to practice a few simple safety measures while using it. The fact that it puts out a very pure form of oxygen also makes it a special case, and more volatile than other medical machines. It's still a very safe piece of medical equipment to use, and our portable oxygen concentrators are even safe to use on airplanes, as approved by the Federal Aviation Administration.
You'll stay safe if you just follow a few simple safety guidelines while using your oxygen concentrator. You can find even more safety instructions in the owners manual of your oxygen concentrator.
Staying away from heat and flames is the most important thing you can do to stay safe while using an oxygen concentrator. Oxygen itself won't explode or combust when coming in contact with flames. It's a non-flammable gas, and won't go up in flames like gasoline fumes. However, a high purity of oxygen feeds a flame quicker than regular air, and you know how quickly a flame can ignite just in the air in a room.
