When does a PASS alarm activate after being motionless?

• A. 10 seconds
• B. 30 seconds
• C. 1 minute
• D. 5 seconds

Answer: (B)

A Personal Alert Safety System (PASS) alarm is designed to enhance firefighter safety by alerting others in case a firefighter becomes incapacitated. The PASS device is activated when it detects a lack of movement for a specified period, signaling a potential emergency situation. A 30-second interval is standard for PASS alarms to activate after a firefighter has been motionless. This time frame allows for a brief pause in activity, such as during observation or planning, while still providing a timely alert to prevent prolonged silence in case the firefighter is unable to call for help. In contrast, shorter activation times like 5 seconds or 10 seconds may not account for brief periods of stillness that do not indicate an emergency. A longer duration, such as 1 minute, could delay alerting teammates, which is critical in ensuring timely rescue operations for any firefighter in distress. Thus, 30 seconds strikes a balance between sensitivity and practicality in emergency situations.
