Clear, unambiguous radio phraseology is essential to safely end a Mayday. To announce a Mayday cancellation, the exact phrase used is “MAYDAY is canceled.” This direct statement removes any doubt about whether the distress signal is still active and tells all crews to cease the Mayday procedures and resume normal operations. The phrase should be spoken by the person who declared the Mayday or by incident command once the situation is resolved, and it’s best repeated to ensure everyone hears. Other options sound more formal or vague and don’t communicate cancellation of the distress status as clearly, which can lead to confusion on the fireground.
