Protector / Protection of firefighters

Firefighters are the first to respond in the line of disaster, and they often encounter some dangerous situations.
Therefore, we come up with the Protector, a belt which can not only light up but also store oxygen. In order to eliminate the heavy weight of the oxygen tank and have something be noticeable in thick smoke, we decided to invent this belt.
It can not only store oxygen in the belt but also transfer kinetic energy when the firefighters are running into electric energy and then light up. If firefighters can wear this,they can eliminate the weight of the oxygen tank and inform one another their location.
