A backdraft is a dramatic event caused by a fire, resulting from rapid re-introduction of oxygen to combustion in an oxygen-depleted environment; for example, the breaking of a window or opening of a door to an enclosed space. Backdrafts present a serious threat to firefighters. There is some controversy concerning whether backdrafts should be considered a type of flashover (see below).
A backdraft can occur when a compartment fire has little or no ventilation, leading to slowing of gas-phase combustion (due to the lack of oxygen); combustible fuel gases (unburnt fuel vapor and gas-phase combustion intermediates such as hydrocarbons and carbon monoxide) and smoke (primarily particulate matter) remain at a temperature hotter than the auto-ignition temperature of the fuel mixture. If oxygen is then re-introduced to the compartment, e.g. by opening a door or window to a closed room, combustion will restart, often rapidly, as the gases are heated by the combustion and expand rapidly because of the rapidly increasing temperature.

Great video showing what a backdraft looks like. This fire happened in downtown Nanaimo BC, Canada on March 30, 2016. I assume that air was introduced on the right side of the building off camera.

Alfred Morris was a running back for Florida Atlantic in college, but he don't have the makeup to play there in the pros. But can he earn a draft pick as a fullback?

A whopping 41 cars in this Track Time presentation! Since the Hot Wheels Super 6-Lane Raceway has 6 lanes, I raced 6 cars 6 times to get 6 winners then raced those 6 winners to find an ultimate winner! If you're wondering why 41 cars, it's because when a model won the first race of 36 cars, he was set to the side and a replacement car joined the event. Here are the 2015 K unboxing videos that were used for selection of cars for this Track Time presentation. If you just to 13:04 of the Double-Unboxing video, you can see part of my studio as well as the contents of all thr...
