Which duration matches the PBE?

Which duration matches the PBE?

• A. 13 minutes
• B. 15 minutes
• C. 17 minutes
• D. 19 minutes

Answer: (B)

PBE duration is about the air supply life of protective breathing equipment. The equipment is designed to provide breathable air for a fixed period, typically 15 minutes, which is why 15 minutes is the correct match. This standard duration gives crew enough time to don the gear, manage the situation in smoke, communicate, and move to safety before the air supply runs out. The other options don’t align with the PBE’s rated air life, so they don’t reflect the equipment’s standard performance under normal conditions.
