What does PASS stand for and why is it important?

• A. Public Address Safety System
• B. Personal Alert Safety System; sounds an alarm if a firefighter is motionless, aiding rescue.
• C. Portable Auger Safety Sensor
• D. Personal Alarm System for Supervisors

Answer: (B)

Personal Alert Safety System is a wearable safety device that signals if a firefighter remains motionless in a hazardous environment. When it detects no movement for a preset period, it emits a loud alarm to alert nearby teammates and incident command, guiding rescuers to the downed firefighter quickly. This rapid signaling is crucial in smoke-filled, dark, or collapsing environments where visibility is poor and time matters. The device is designed to stay active as long as the wearer moves, and it can be reset or silenced by active movement, helping prevent false alarms while still providing a clear emergency signal. The other names describe systems that aren’t the standard firefighting PASS terminology or functionality.
