Which signal is considered a distress signal for firefighters apart from a mayday?

• A. PASS device alarm.
• B. A routine hand signal for 'okay'.
• C. A shout for attention.
• D. An emergency vehicle siren.

Answer: (A)

In this context, the PASS device alarm serves as a built-in distress signal that crews rely on when a firefighter cannot call for help verbally. The Personal Alert Safety System is worn by each firefighter and is designed to alert nearby teammates and incident command if the wearer stops moving for a set period or manually activates the alarm. That audible alert (and often a location cue) helps others quickly locate and assist someone who may be incapacitated in zero-visibility conditions. It functions independently of a verbal Mayday, making it the recognized internal distress signal. The other options don’t serve the same purpose: a routine hand signal for “okay” is just a status update, not an emergency cue; a shout for attention can be easily lost in noise and smoke; a siren on an emergency vehicle is an external warning and not a signal transmitted by the distressed firefighter to their team.
