Which feature on SCBA gear is designed to alert teammates if a firefighter stops moving or is incapacitated?

• A. PASS (Personal Alert Safety System).
• B. Regulator purge valve.
• C. Low-air alarm.
• D. Facepiece anti-fogging system.

Answer: (A)

The Personal Alert Safety System (PASS) is designed to alert teammates if a firefighter stops moving or is incapacitated. It continuously monitors motion and, if there’s a period of inactivity or if the firefighter manually triggers it, emits a loud, distinctive alarm that others can hear and respond to. This audible cue helps the team locate and reach the individual quickly in smoky or low-visibility environments, enabling an immediate rescue or intervention. Some PASS units also provide a visual indication or data to teammates about the alarm state, reinforcing rapid deployment of assistance. In comparison, a regulator purge valve serves to clear the regulator; a low-air alarm warns the wearer when air supply is running low, which is a self-use alert rather than a team alert; and a facepiece anti-fogging system is about maintaining visibility, not about signaling distress.
