What I already know about this topic

I know a lot about my topic because I do it every day. I know that many fear fire and what it can do to them or their homes. I also know many people do not really understand what fire is I mean by this they have never seen or been right up close to one. they have never been in a back draft, air becomes super heated and cause a push on the structure which causes an explosion, or flash over, when fire is hidden in walls floors were firefighters are unaware of its being it will in about 30 seconds turn black as night and the building will erupt in toxic gases and soon turn to fire burning anything in its path. I also know that some work hard and want to be in a service job helping others and risking their life while doing it. Like me but when you get going you do not think of yourself your on the person in the "danger zone"
