Which statement best describes the meaning of a PASS alarm during interior operations?

• A. A PASS alarm indicates ventilation is ready.
• B. A PASS alarm means moisture level in gear.
• C. A PASS alarm indicates a firefighter in distress and requires team coordination.
• D. A PASS alarm is a signal that all clear.

Answer: (C)

A PASS alarm is a distress signal from a firefighter inside a hazardous environment, indicating that someone needs urgent help and requires immediate team coordination to locate and assist. The device activates when a firefighter stops moving for a set period or manually triggers it, and it alerts nearby teammates to locate the firefighter and execute a rescue plan, often involving a rapid intervention approach. It is not a signal that ventilation is ready, nor a readout of moisture in gear, and it does not mean all clear. When heard, the response is to stop what you’re doing, locate the distressed firefighter, confirm their status, and initiate rescue and accountability procedures quickly.
