Hopefully there were no injuries to anyone related to this incident, once they got the front opened up and the fire shot out, the explosion came unexpected. Maybe propane tanks for forktrucks blew. Thank you to all firefighters for protecting the citizens of your coverage area.
That's called a smoke explosion, or sometimes called a backdraft. All of that smoke that you see is actually combustible gas and particulates, but it's not hot enough to burn because it cools as it escapes the building. Inside the building, that trapped smoke is definitely hot enough to burn, but it can't burn because there's not enough oxygen inside to support combustion. When the building is opened, and air is let in fast enough that the smoke doesn't have time to cool below its ignition temperature, it starts burning hot and fast, making it look like an explosion.
Completely agree. Its only a matter of time before the armchair Firefighters show up. Seems like they are everywhere now. I love how none of them have little to any experience on an actual fireground yet tell all of us how it's supposed to be done. They are a joke and would get people hurt if they were ever on an actual fireground.
