The first step, as it is for most things, is realizing that you have a problem. For our purposes we can assume that your problem is not you. Your problem will be something of or relating to your safety and/or the safety of those you care about. Living in fear is foolish but to be prepared is essential. Preparedness is the key to surviving anything. If you are not prepared to act on a moments notice then your odds of survival diminish exponentially. No matter what the problem is you must have a plan.
