in testing for unanticipated events, what are the key take-away's for a facility or business? What should everyone walk away with, and what should be done with that information?

Probably several emergency plans. Having only one plan to handle any emergency is not smart.

Example:
At a high school where I used to teach, we had one fire drill/evacuation plan -- everyone was to go to the football field, gather there, students with their classroom teacher that period, and take roll so we'd know if anyone was missing.

However, to get to the football field, 2/3rds of the school had to go past the swimming pool -- and one day the emergency was a chlorine leak in the pool's equipment! The administrators and counselors had to hustle and get everyone to go back to the classrooms -- except for the PE classes, of course! That experience made everyone understand that there needed to be different emergency plans based on what the problem was.

1. Where else to evacuate if going to the football field was not safe?
2. How to handle an evacuation if the emergency occurred when students were NOT in class? (during lunch or during a passing period)
3. How an earthquake drill/evacuation was different from a fire or chemical evacuation?
Etc., etc., etc.

Bottom line -- you cannot anticipate everything, but you can have a variety of plans drawn up so that at least one plan (or a combination of two) would work reasonably well.

The admins also realized that there needed to be more than one drill a year! We started having one a month -- during different classes, during lunch, during passing times -- different circumstances each time.

This never ends. These kinds of plans need to be continually considered, reconsidered, practiced, etc.
