Now the first thing that you need to realize, is that when a building is on fire, it becomes a situation where only the fit can survive. the classic survival of the fittest theory kicks in, and despite it sounding a little odd, it is what dictates just who will make it out before the others.
This is why you need to figure out just how it is that you can stay fit. You need to constantly take care of yourself and stay in shape. Going to the gym and working out will help you cope with and lift heavy weights in case of an emergency. At the same time, if you get in a lot of cardio, you can go on and stay active for even longer, which means that you will be able to help more people.
So remember to get in some gym training and some cardio exercises as well at all times.
The next thing you need to do, is to keep a cool head. Remember that when people are going to be in a burning building, they are not going to be able to control themselves. Their emotions will be running at an all time high, and they will end up being unusually annoying and troublesome.
In order to try and make sure that you don't let this impact you, practice to stay positive and learn how to take control of a situation. The more enforcing you are, the more likely you are to create an escape route and then go on and save anyone who needs saving.
