Survival Survival School 30 Tips for Surviving a Shooting These are DOs and DON'Ts from Bob Stuber's Survival School that apply anywhere. Do create a personal emergency plan ahead of time with your family. Do make note of where all exits are and where they lead to.
Some exits are for another room or building or floor.
Know how to get out. Do leave doors open, they can provide added cover. Do dial 911 and leave the phone near the hook as you try to get away. That way emergency crews know where the problem is. Don't hide under the desk - it does not provide enough protection, making you a sitting duck.
