What should you do if a smoke detector is triggered by dust or steam during training?

• A. Ignore and continue training.
• B. Reset the detector and proceed.
• C. Inform air traffic control.
• D. Treat as a risk per SOP and report to the instructor; ensure proper troubleshooting.

Answer: (D)

The important idea is to treat any detector trigger as a safety signal and follow the established procedure for abnormal but non-fire events. Dust or steam can set off a smoke detector without there being an actual fire, but you still respond as if there is a potential hazard to ensure everyone’s safety and to verify the situation.

So, the proper action is to treat it as a risk and report it to the instructor, then follow the troubleshooting steps in the SOP. This means pausing as needed, notifying the person in charge, and working through the checklist to determine the source of the trigger, whether it’s a nuisance from dust or steam, and whether the system should be reset or inspected before resuming. This approach preserves safety, ensures responsible handling of the situation, and prevents complacency.

Ignore and continue training isn’t appropriate because you can’t dismiss a detector alarm, even if it’s likely a false trigger. Resetting the detector and proceeding skips necessary verification and could hide a real issue. Informing air traffic control isn’t the correct channel for this scenario in training; the instructor and the aircraft’s SOP are the proper line of communication for such events.
