What is the main purpose of the PASS device?

• A. To regulate a firefighter's breathing rate.
• B. To monitor ambient temperature around the firefighter.
• C. To alert others if a firefighter is immobile or in distress and to aid rescue.
• D. To track the firefighter's location using GPS for later review.

Answer: (C)

A Personal Alert Safety System is a wearable safety device that continuously monitors a firefighter’s movement and will emit a loud alarm if the wearer becomes motionless or presses the alert switch. This immediate alert helps teammates locate and reach a firefighter in trouble, especially in smoke, darkness, or heat where visibility is poor. The audible alarm (and sometimes a light) tells the crew that someone may be incapacitated and needs rescue, so it directly supports rapid rescue actions. This isn’t about regulating breathing rate, or monitoring ambient temperature around the firefighter, or tracking location with GPS for later review. Those functions aren’t the primary purpose of a PASS device; its main role is to warn others and aid in locating and rescuing the wearer.
