As an oxidizer, medical oxygen can be dangerous because it causes materials to burn faster and hotter than in a typical fire event. Oxygen can soak into clothing, hair and bedding making it very easy for a fire to start and spread. Knowing the safety risks is the best way to prevent a serious injury.

Smoking and open flames

Smoking materials are the main cause of fires, injuries, and deaths involving medical oxygen.

  • Do not smoke: there is no safe way to smoke in a home where oxygen is used or stored. This includes cigarettes, pipes, cigars, cannabis and electronic cigarettes.
  • Post warning signs: place "no smoking" signs at the entrance of the home and in any room where oxygen is used or stored.
  • Avoid open flames: do not use candles, matches, woodstoves, or lighters. Keep oxygen cylinders and concentrators at least 1.5 metres (5 feet) away from stoves or any other heat source.

Sparks and heat

  • Avoid electric tools: do not use items that can cause sparks, static-electricity, or friction near oxygen including electric shavers, hair dryers, grinding tools and friction toys (such as pull back toys).
  • Keep away from heat: store oxygen tanks and concentrators far away from electrical devices and open flames.

Oils and sprays

Items that contain oil or grease can catch fire easily when oxygen is present.

  • Check lotions and creams: do not use petroleum jelly (Vaseline), oily lotions, face creams, or hair products while using oxygen.
  • Keep hands clean: ensure hands are free of oil or grease before handling oxygen equipment.

Avoid aerosol sprays: do not use spray cans such as hairspray or cleaning sprays near oxygen equipment. These often contain materials that can catch fire.
