What safety feature should be activated if you become disoriented while using SCBA?

Activating the PASS (Personal Alert Safety System) device is crucial when a firefighter becomes disoriented while using a self-contained breathing apparatus (SCBA). The PASS device is designed to alert other personnel of a firefighter's location and status, helping to ensure prompt rescue if needed. It generates a loud audible alarm after a preset period of inactivity, allowing team members to locate an individual who may be in distress or has become incapacitated.

This feature enhances situational awareness and safety within a potentially hazardous environment, such as during firefighting operations where visibility is poor and conditions can change rapidly. By using the PASS device, a firefighter can signal to their team that they are in trouble, which is essential for effective rescue operations. Such proactive safety measures are vital in emergency situations where every second counts.

Other options, while they have their respective roles in fire safety and equipment function, do not specifically address the immediate need for alerting others in the event of disorientation.
