After how many seconds of no movement will the PASS device emit a low level alarm?

The PASS (Personal Alert Safety System) device is a critical safety feature for firefighters, specifically designed to alert others when a firefighter is in distress. The device activates a low-level alarm after a period of inactivity, which serves as an important indicator of a firefighter's condition.

In this case, the correct answer indicates that the PASS device emits a low-level alarm after 30 seconds of no movement. This duration is significant because it strikes a balance between allowing time for legitimate pauses or brief stops that may occur during firefighting operations and ensuring that a potentially incapacitated firefighter can be quickly identified and assisted. A shorter timeframe might lead to false alarms that could disrupt operations, whereas a longer one could delay the alert in a dangerous situation.

Understanding this timeframe emphasizes the importance of constant movement and awareness in high-risk environments, highlighting the retrospective benefit of the PASS device in increasing safety and response efficacy in emergencies.
