How long do the PBEs generate oxygen when activated?

• A. 10 minutes
• B. 15 minutes
• C. 20 minutes
• D. 25 minutes

Answer: (B)

The correct duration for oxygen generation when Portable Breathing Equipment (PBE) is activated is indeed 15 minutes. This time frame is crucial for ensuring that individuals can maintain adequate oxygen supply in emergency situations, particularly during smoke or fire events on board an aircraft. The 15-minute duration is generally considered sufficient for passengers and crew to either secure their evacuation or to reach a safe area where air quality is restored. In practice, this 15-minute operation time must be carefully communicated and understood by all relevant personnel to ensure preparedness during emergencies. Understanding this aspect also highlights the importance of regular training and familiarization with safety equipment available on aircraft.
