Portable Medical Oxygen Cylinders are utilised to provide a temporary uninterrupted oxygen supply to patients. They may be used where, for example, a patient is being moved on a stretcher from an ambulance to a hospital trolley /bed or vice versa, or in the home environment. 

Oxygen is non-flammable but strongly supports combustion and under high pressure with certain conditions, can cause common materials to ignite suddenly (including some materials which do not normally burn in air).  It is highly dangerous when in contact with oils, greases, tarry substances and many plastics.
