Before the training took place, mountaintop spoke with public information officer Nick Fleming about the importance of knowing when a flash over will occur. Okay, so today we're going to be going over our flash over training. This is a required class for all new firefighters to attend. It consists of four hours of classroom powerpoint and then four hours of the actual live burn which is the trailer behind me here. This is just where we have an elevated structure. We build a fire in a box basically and the students can observe the flash over occurring. We talk about kind of the signs of a flash over. That way if the firefighters are in that situation in real life they can kind of see it before it happens. According to the United States Fire Administration, a flash over is a thermally driven event during which every combustible surface exposed to thermal radiation in a compartment or in closed space rapidly and simultaneously ignites. Instructor Robert Lindsey reveals how the operation works. We have firefighters and instructors inside the facility. It is a two stage or two level facility. The front section is the high temperature area where the fire is actually at. The smoke and the unmarked fuels will build up. They get to the proper ignition temperature and point that will auto ignite and fill the trailer with a flame that goes from starting from the ceiling down toward the floor area. The process for the interior crew or the candidates is they're staggered along the walls and each time we have a flash over we will do a rotation. The one in front will rotate back to the back. We do that hopefully right now we have six candidates in there who will hopefully go through three rotations and bring them out and reset the process. Afterward we spoke with EKU fire investigator student Mary Cottle and recruit Cole Tackett about the experience. Well in my career I have to know fire behavior too like the events leading up the flash over. So doing this really I got to experience flash over so for my career it will help me better understand the events leading up to it and the signs of it and know the fire behavior of it. It's one thing to learn in the classroom. It's a lot better experience learning it in the trailer so that way you can visibly see and feel and hear. Use all your senses to tell when it's going to flash over. It's thick black smoke it's really hot and you can't see nothing. So those are the signs of a flash over. You can also learn the science behind it in the classroom and so I definitely have a better understanding and hopefully this could take my life maybe my fellow firefighters lives one day and you know just get the situation under control before it happens.
