The main idea here is that a Mayday signals immediate danger and a call for urgent help. In this phase framework, that immediacy and need for rapid assistance places you in Distress—the moment danger is present and you require immediate rescue or intervention. A fire creates time-critical danger, so a Mayday is the distress signal used to summon help right away.

Uncertainty is when the situation isn’t fully known yet, Alert is recognizing a potential problem that could become serious, and Emergency refers to a situation where danger is present and an active response is underway or the situation has escalated beyond distress.
