Little Drops Of Water & Application of Water


So when is it a good idea to use a Fog Attack or a Combination Attack? When should we set our Fog Nozzle on a fog pattern? When Should we set our Fog/combination nozzle on straight stream? Do we push fire and if so; when? Does the setting of the nozzle effect te ability to push fire? Is there ever a time we would want to push fire? When is it ok to apply water from the outside?

  1. Do fire streams “push” fire? According to the science? No, the fog entrains air and creates a pressure that pushes the gasses and smoke. Fine, but isn’t the result nearly the same? If the gasses and heat being moved by this pressure front are not sufficiently cooled before reaching ignition temperature, say on the other side of a doorway, then the result is the same. The fire moved. A flashover creates enough energy to initiate a flashover in another room, provided it is properly charged with smoke and gasses. So are “smoke explosions” seen on youtube a series of stacked flashovers from room of origin to the flowpath inlet? Who Cares? The result is the same, runaway oxidation in the modern fire environment.

    Interior fire operations where the crew is not isolated from the fire room should keep their combination nozzles on straight stream to entrain as little air as possible while providing cooling to gasses and fuels. Transitional type attacks on rooms of origin or flow path inlets I believe still are better served with narrow streams directed to the ceiling to maximize the cooling of gasses while excess rain-down positively affects fuel packages.

    Or I’m wrong. I also like black over red fire apparatus, traditional leather helmets, and mechanical Federal Q’s, if anyone wants to fight about that.

    • Tim- I think that you are exactly right. We need to apply water directly to the fire as quickly as possib
