Closed-Circuit SCBA

A Closed-Circuit Self-Contained Breathing Apparatus (SCBA) is a device that allows a person to breathe safely in environments with harmful air, such as in firefighting or hazardous material situations. Unlike open-circuit systems that release exhaled air, closed-circuit SCBAs recycle air by removing carbon dioxide and adding oxygen, allowing for longer use. They consist of a mask, air supply tank, and a system for handling the air you breathe out, making them efficient for extended operations. This technology enhances safety and endurance in critical situations where clean air is essential.
