What safety device must a member use when operating in or near a collapse zone without an SCBA?

When operating in or near a collapse zone without a self-contained breathing apparatus (SCBA), the use of a stand-alone Personal Alert Safety System (PASS) device is essential for ensuring safety. The PASS device is designed to emit a loud alarm if a firefighter becomes incapacitated or fails to move for a specified period. This feature significantly enhances the chances of a quick rescue if a member becomes trapped or unable to signal for help while working in hazardous conditions, such as those presented in a collapse zone.

The key function of the PASS device is to provide a clear audible signal that helps rescue teams locate an affected firefighter, thereby improving overall safety and response time in emergency situations. This makes it a crucial safety device in areas where structural integrity is compromised, and the risks of further collapse or injury are high.
