Which of the following PASS device features is NOT currently approved for LAFD use?

• A. Monitor battery status
• B. Bluetooth technology (not currently approved for LAFD use)
• C. Monitor air cylinder pressure
• D. Monitor time remaining on air

Answer: (B)

The key idea here is reliability and independence of life-safety equipment. PASS devices are meant to be self-contained, delivering critical status information without relying on other devices or networks in a hazardous environment. Monitoring battery status, monitoring air cylinder pressure, and showing the time remaining on air are all metrics that the device can measure and display on its own, ensuring a firefighter can understand the device’s health and their air situation at a glance, even in smoke or low-visibility conditions.

Bluetooth connectivity, while useful in other contexts, introduces potential points of failure for a device that must work every time. It would require pairing, a compatible external device or app, and ongoing software maintenance. In a fireground setting, signals can be disrupted by heat, EMI, or obstacles, and external devices may not be readily available or accessible. Additional battery drain and cybersecurity concerns further argue against relying on Bluetooth for PASS functionality. For these reasons, Bluetooth technology is not approved for LAFD PASS devices. The other three features remain approved because they provide essential, self-contained information without depending on external systems.
