Precautions while using Oxygen Therapy
Always plug your oxygen concentrator
Always plug your oxygen concentrator into a grounded electrical outlet. Never use an extension cord or power board. As the oxygen concentrator becomes hot when in use, locate it in a well ventilated area, away from curtains or drapes. Have your oxygen concentrator inspected and serviced regularly according to the suppliers instructions. Store oxygen cylinders in an upright secure position in a well ventilated area away from any open flame, heat source or direct sunlight. Do not cover with cloth or plastic. Handle oxygen equipment with care to avoid damaging cylinders.
