A PASS alarm activates to indicate which condition?

A PASS alarm activates to indicate which condition?

• A. Movement is excessive
• B. A firefighter is motionless for more than 30 seconds
• C. Gas detected
• D. Low battery

Answer: (B)

The main idea is that a PASS (Personal Alert Safety System) is designed to summon help if a firefighter stops moving. It watches for motion, and if there’s no movement for about 30 seconds, it automatically sounds and flashes to indicate distress so teammates can locate and assist. That’s why the condition described—being motionless for more than 30 seconds—is the correct trigger. The other options refer to different alarms: excessive movement isn’t what triggers PASS, gas detectors alert for hazardous gases, and a low battery warning is about power status rather than producing the PASS distress signal.
