From rodents to regulations to fires to...well...almost any disaster, it is good to think ahead. While one can't plan for every detail, certainly one can gather go-to people that can help when you need it right now.
Here is a book I read a while back from a company which I first met while taking a continuing education course. I have enormous respect for them and the president, Richard Levick, is very smart but also a nice person, and very approachable.
