I have done gas cooling for most of my 30 year's of service. This nails what I see. Straight stream goes through the gasses and cools the surfaces . Colling the hottest part first. Cooling ahead. As it steams off the surface it cools the gases. Once you see the seat of the fire a couple of pulses. That steam release will cool more gasses. Best part is this is easy to teach, don't require expensive kit, and works for most situations. P.S. Australian Fire Fighter.
The key to any residential fire is to turn off combustion as quickly and safely as you can. That means, find the fire room from the exterior, break out the windows, to give the heat and gasses a direct route out of the structure and away from any victims, and then apply tank water onto the burning material. All the gasses including water vapor, continue flowing out those windows. Now, the firefighters go into a much safer environment to mop up while they search for the victims. That exterior fire suppression can be accomplished before an entry team can be assembled, get fully dressed and get the front door open so no rescue time is wasted. Going into a burning building to extinguish a fire that can be extinguished quicker and safer from the exterior makes no sense whatsoever. I don't care how you apply the water from the inside, you will be standing IN the steam bath!
You dont need to use anywhere as much water as that as all you do is create shit loads of steam. Try pulsing with a wider cone to start with then narrow down the cone as you push the fire back. Far easier and much more comfortable
Three things. Why would you waste your time adjusting the stream pattern in an idlh environment. A wider patter makes more steam. There is no such thing as too much water. You can dry stuff out but you cant un burn it. Stop worrying about too much water. Its not enough until the fire is out.
@@crustytomato5164 You obviously don't understand fire behaviour very well. Wider pattern on a pulse uses less water which also creates more droplets which give you more surface area which in turn reduces the heat quicker and creates less steam. If you charge in with it on a tight jet all you do is waste much of the water as its not absorbed. If the fire is rolling over your head wide pulsing fan and narrow down as you knock it back. I take it don't spend much time training at a fire behaviour venue.When you watch those guys you can see that there is shit loads of water on the floor. Which hasn't been absorbed. We use high pressure hosereels at 100 litres a minute on a half jet/half fan we use shit loads less water than these guys by quick sharp pulses. The fine mist is far more effective than your solid stream. Every litre of water you use in a fire compartment creates 1700 litres of steam. That is the expansion rate. So if you guys go charging in and whack an open jet which let's say you use 30 litres of water then you will create 30 x 1700 litres of steam. The only time you won't do that is if its a really small fire and you knock it out with a couple of pulses. I take it you are not a career firefighter with continuous very good training if you use comments like you did about you can never use too much water?
@@crustytomato5164 "There is no such thing as too much water." That's what everyone says just before they run out and because they weren't surgically applying the water and the fire is still burning when they do run out. This is how you address the JOB! "Eliminate the threat quickly and safely while using the least amount of water." That requires thinking rather than Fountain Statue squirting.
Genius. This man knows his stuff

Thank you for the video
