SN instructed patient / caregiver about a few simple precautions that can be taken to create a safe home environment when using oxygen. Oxygen canisters should be kept at least 5 - 10 feet away from gas stoves, lighted fireplaces, wood stoves, candles or other sources of open flames. Do not use electric razors while using oxygen ( These are a possible source of sparks ). Do not use oil, grease or petroleum - based products on the equipment. Do not use it near you while you use oxygen. These materials are highly flammable and will burn readily with the presence of oxygen. Avoid petroleum - based lotions or creams, like Vaseline, on your face or upper chest. Check the ingredients of such products before purchase. If a skin moisturizer is needed, consider using cocoa butter, aloe vera or other similar products. For lubrication or rehydration of dry nasal passages, use water - based products. Your pharmacist or care provider can suggest these.
