I was recently in Las Vegas at a convention and trade show and was sitting at a table and was speaking too a group of people when someone interrupted and asked where the first aid station was and where they could go to get someone looked at. This is a bit disconcerting as I was one of the organizers of the event. I had no idea where the attendee could get help.
As it turned out the person was having some issues related to their blood pressure medicine and a scary moment was turned into a not so scary moment. It did however teach me a lesson. Everyone on your organizational staff must know all about emergency procedures, including fire escape plans and in this case, where the first aid station is located. Had this person had a more serious problem, the difference between surviving a bad event and not could be the fact of getting help as soon as possible. Before your event or show begins, sit down with everyone and go over a disaster preparedness plan and all other possible emergency procedures.
