David Maeker different take on fire growth in relation to oxygen. Great stuff.

So have there been any studies to see the measured amount of O2 a fire consumes in a given time? For instance in the video you show the “study” house closed up and basically have nothing showing. The time measured O2 consumption of a structure?

Great explanation of fire growth to the new guys. Ventilation and fire attack go hand in hand. You manage both the fire will go out.

Now you are putting out extremely useful information. But there is more that needs to be done showing how surfactants and bubbles work to change the way water behaves when applied to the fuel rich and oxygen limited fire. Absorb the fuel into the bubbles of surface active agents and cool the heat.

When I was a fireman, I was amazed by how fast high-pressure fog will knock down a fire while shielding the user from extreme heat.

Next year please look at how a good CAFS can be used clear the air of heat AND carcinogens in the smoke without ventilation feeding the fire oxygen. It is so much more important than studying how to squirt water at a fire.

It is important that the firefighters understand how a tiny bubble works to extinguish fires. Consider how much heat a gallon of water can absorb before boiling into steam. The gallon of water must absorb enough heat to reach 212 degrees farenhieght. Have you ever tried to boil a gallon of water. It would take a very long time if you placed the gallon into a hot oven such as a house fire. Now consider if the gallon of water was stretched into a million tiny bubbles that exposed a much larger surface area to the heat, that would take much lest time to absorb enough heat to reach the boiling temperature. Then the gallon of water expands into 1,700 times its original volume in the form of steam that displaces oxygen and dilutes fire gases. Now then when the heat has been absorbed and the fire gases have been diluted the fire goes out and the steam begins to cool and condense back into liquid form and the heat and fire gases contract back to original volume. Now here is when the surfactants come into play, the bubbles stay where you put them and don't run off like water does. The surfactant causes the bubbles to share the water with the surfaces they are on and anything that is wet can not get hotter than 212.f and that is not hot enough to cause any more fire or smoke. So I believe that when fire fighters understand how CAFS foam works to put more fire out faster and requires much less water it will make their job much less difficult and much safer for them and for the citizens they are working to save lives and property.
