What is the duration of the PBE?

Explanation:
PBE duration refers to the amount of breathing air the device provides, and PBEs are built for quick, emergency use rather than long operations. They’re designed to give you just enough air to exit a hazardous area or complete a brief entry, typically about 15 minutes. That’s why 15 minutes is the best answer. A shorter duration like 10 minutes wouldn’t match standard PBE specifications, while longer times such as 20 or 25 minutes would imply a different, longer-duration system.
