Medical oxygen is mainly transported to hospitals by specialized oxygen supply stations. Because oxygen stations are high-risk work environments, the stations are usually located in more remote places. It is still recommended to fill the oxygen at the hospital.
Oxygen tanks can be used as oxygen supply equipment in hospitals, first aid stations, home care, and battlefield rescue. Oxygen tanks should be placed as far as possible to avoid close to open flames or heat sources, it is also best not to be subjected to direct sunlight.
