Oxygen tanks are containers that store oxygen gas under high pressure. They are commonly used in various settings, such as hospitals, scuba diving, and for people with breathing difficulties. The tanks allow users to breathe in pure oxygen, which is essential for maintaining good health and supporting life. These tanks come in different sizes and are made from strong materials to ensure safety. When using an oxygen tank, it’s important to follow safety guidelines, as the high-pressure gas can be dangerous if not handled properly. Proper maintenance and regular checks are also crucial to ensure the tank functions effectively.
