Which protective device is designed to alert teammates if a firefighter becomes immobile?

• A. SCBA
• B. Thermal imaging camera
• C. Helmet microphone
• D. PASS device

Answer: (D)

The key idea here is a safety beacon that automatically calls for help if a firefighter stops moving. A Personal Alert Safety System (PASS) is worn with the breathing apparatus and monitors motion. If the wearer becomes immobile for a set period, the PASS emits a loud alarm and may flash lights to warn teammates of the firefighter’s location and distress, so rescuers can respond quickly in a smoky or low-visibility environment. This direct, automatic alert is what makes it the best choice for signaling when someone is in trouble.

Others serve different purposes: the respirator setup provides breathable air but doesn’t automatically alert others if you’re immobile; a thermal imaging camera helps you see through smoke but doesn’t alert your teammates if you’re stuck; a helmet microphone is for communication, not for signaling distress.
