Скачать или смотреть Quick Clips: Pushing Fire

While there are varying schools of thought in the fire service about ‘pushing fire,’ perhaps none of our videos could be more clear than this example. While an attack line cannot physically ‘push’ a flame (it would only extinguish it), it can push a change in conditions. Opening an attack line can upset the thermal layering, entrain air into the stream, and push smoke, gases, and unburned particulates. This can then create an opportunity for the fire to ignite that combination in a new location. In this clip, you can clearly see that the two story, single family home is well involved and self ventilating out of any opening it can find. When the firefighter opens the nozzle for attack, the entrained air provides much needed oxygen to ignite the heavy black smoke and particulate exiting the attic dormer. This lights off, providing an excellent example of how a hose line can ‘push fire.’ These crews continued an excellent interior attack, then extinguished this fire and saved the structure.

Our video guy recently found dozens of short clips that he edited from fires ten (and more) years ago. These ‘Quick Clips’ might be an excellent jumping off point for other firefighters to discuss strategies and tactics. We will try to post more in the future.
