For how long does the Protective Breathing Equipment (PBE) provide oxygen?

The Protective Breathing Equipment (PBE) is specifically designed to provide flight attendants and crew members with supplemental oxygen in emergencies where smoke or toxic fumes are present. It typically offers a duration of approximately 15 minutes of breathable oxygen, which allows crew members to perform necessary tasks such as evacuation, firefighting, or assisting passengers while maintaining a safe oxygen supply.

This duration is calculated to provide enough time for crew members to operate effectively in a hazardous environment and to help mitigate the situation or ensure passenger safety. Understanding the duration of oxygen supply is crucial for effective emergency response, as it influences how crew members strategize their actions during an emergency.
