What is the primary function of the PASS device?

The primary function of a Personal Alert Safety System (PASS) device is to alert if the firefighter is inactive. This device is a critical safety tool designed to enhance the safety of firefighters, particularly in emergency situations where a firefighter may become incapacitated or unable to move.

When a firefighter becomes inactive for a predetermined amount of time, the PASS device emits a loud alarm to alert others to their situation, helping ensure that the firefighter can be located and assisted quickly. This alerts other team members to potential danger and helps facilitate a prompt rescue.

While the other functions mentioned in the choices have their roles in firefighting operations, they do not represent the main function of a PASS device. Rather, the PASS device specifically aims to prevent accidents related to inactivity and keep firefighting personnel safe.
