What is a key characteristic of a Personal Alert Safety System (PASS)?

A key characteristic of a Personal Alert Safety System (PASS) is that it must be tested daily and maintained to ensure it functions effectively in emergency situations. This system is designed to alert others when a firefighter becomes incapacitated or is unable to signal for help. Regular testing is crucial because it ensures that the device is operational when needed.

Daily checks and maintenance include verifying that the battery is charged, confirming that the alarms work properly, and ensuring that all components are in good condition. This level of diligence helps to prevent equipment failures during critical moments. While there are various features associated with PASS devices, the emphasis on routine testing and maintenance is foundational for their reliability and effectiveness in potentially life-threatening situations.
