Does anyone have a list of things to check for before starting an investigation? Not the usual safety concerns, but a list of things they check to make sure they are shut off or at least that we should be aware of in advance?
I fly by the seat of my pants and know to watch for the obvious things like having everyone shut off their cell phones and if the location has WiFi, but I don't want to backtrack or waste time after the investigation begins because I missed something that should have been obvious.
