Precautions while using Oxygen Therapy
Oxygen Equipment Safety
Do not store your oxygen system near any heat sources or open flames. Do not expose your oxygen equipment to electrical appliances (such as electric razors, hair dryers, electric blankets, etc.). Check that all electrical equipment in the area near the oxygen is properly grounded. Keep the oxygen system away from aerosol cans or sprays, including air fresheners or hair spray. These products are very flammable. Keep the oxygen system clean and dust free. The person who delivers your oxygen will show you how to do this. Keep the oxygen system in a place where it wont get knocked over.
