An interesting dance of communications. Surely there must be some way to describe risk assessment and decision-making in disaster / emergency situations, but my questions have not succeeded in eliciting that information.

It seems to me subjective decision-making and alertness, pre-suppose some learned standards and methods for deciding and some pre-determined finite list of things to which you choose to be alert. I am probing to try to see what those standards, methods, and things may be for each type of emergency /disaster.

Put another way, I believe you have learned what to pay attention to in an emergency / disaster. What are those things?

One example would be the things posted about fire by Nighthiker. These are not random, made-up-on-the-fly considerations but a specific list of factors.

Edit: surely responders are taught specific things to gauge when to flee?

Edit 2: surely some factors go into deciding evacuation orders?
