The Drager PBE lasts approximately how many minutes?

Explanation:
The main idea here is how long the Dräger PBE provides breathable air. This emergency breathing device is designed with a finite air supply to give you enough time to don the hood, move through a smoky or hazardous environment, and reach safety. For the standard aviation PBE, the manufacturer-rated duration is about 15 minutes under normal breathing at a calm pace. Activity or heavy work can shorten that time, but 15 minutes is the typical planning figure. Shorter durations like five minutes wouldn’t provide enough evacuation time, while longer durations such as 25 or 30 minutes aren’t standard for the PBE used in most commercial aircraft.
