Positive pressure attack!
Wouldn't it be nice to be able to see victims, dangers, and your way around during interior attacks? It is possible in some cases with a technique called Positive Pressure Attack. This is a new concept to me, in fact I had never heard of it before a recent class on the subject. This technique is, to me, easiest but unused approaches to fire fighting. It increases a victims chances of survival and firefighter safety. Like I said this is a new concept to me but is one I feel so strongly about that I had to get the word out about it. Visit www.positivepressureattack.com for more info, take a class and form your own opinion. This is a good way to become more effective at saving lives, doing less property damage, and increasing firefighter safety all with a piece of equipment I would bet 95% of us already have on our apparatus. Please take the time to atleast look into this, I believe it will truely change how your department will conduct interior attacks. Thanks for reading and be safe out there!

Thanks a lot Chris I'll look into this very much so, the info seems great but there are some questions I've got about this type of attack also. What if you lose water pressure or even water all together in your hose line? I see this could be great for a room and contence fire, but like I said I'll look more into this.

Those are questions I asked too. But it is no more dangerous then if you run out of water in conventional interior attack. The blower/ fan will actually help. How? Two ways, first it keep fresh clean air coming in to you. With clean air comes less heat, as it and dense smoke are pushed out of the building. That allows you to exit very rapidly if need be for what ever reason. Our gas powered fan is LOUD, which will also help you find your way back out of the building. But please look into it, Kriss Garcia and Reinhard Kauffmann are great instructors and have plenty of real world experience and are still active in the job. They don't push products on you during thier classes. They simply want to help us do our jobs better.

On all of our fires we use positive pressure fans not only to ventilate after the fires out, but to clear the air while on an attack. Just gotta make sure you know where the fire is and to have water on it or the added air can cause the fire to grow.

We use it and it has been a very useful tool for us when done right .

I agree this is a method in which you MUST HAVE proper training on. But with the proper education it is safe and effective. Also, like I said this is something new to me, but I just wanted to reach those out there like me who have never heard of this.

"Lead off with the fan"........... Very West Coast! I've even heard it from instructors at FDIC. (They were from Aurora, CO)
If it works for your department.... great. It is not for everybody. I still believe the best chance for victims, etc is a quick knock down and coordinated ventilation. My 2 cents.

Positive Pressure attack like anything else will work I am sure in the right conditions and with the right application. the main thing is drilling on that procedure. Drilling on it is the only way to make it work the way it should. Nice information that is very useful. I do love learning about new techniques. There is always something new to learn in the line of work....

We use PPVs on all of our interior attacks and it definately helps. It reduces the heat, reduces toxic and noxious gases, improves visibility, etc. However, I have seen it go bad when positive pressure is introduced to a fire that is too big or the seat of the fire has not yet been located. Shortly after introducing oxygen to an oxygen starved fire, you won't have to find the fire, it will find you! Another consideration is that in order to do this effectively, you have to have the personnel. Someone to set up the fans, a crew to do S&R, a hose line crew, ventilation crew, backup line, etc. If you don't get everyone in place quickly, things can go bad in a hurry.

Training it has to do with your training . Iwas helping a dept. and they told me how they had tried it and they were lucky they did not lose someone . Through a fan in the door as soon as you get there don't get it .

PPV is not new, and have to say training is an absolute must. Point of fact; why would you want to put 25,000 cfm of fresh air into a building allready on fire? If you know where the fire is and where it's going, then be my guest, if not, leave it on the truck.

Positive pressure is a great way to clear visibilty and heat for your rescue efforts and your handline teams it makes the so much easier. If departments would try this in some of there training drills I think they would be suprised how well it works. Dont let the weve always done things this way stop you from trying new things in your training.

PPA is a proven tactic that has been used very effectively. Don't get it confused with PPV, it's not the same thing. I caution, do not attempt PPA without proper training. If not conducted properly, you can "get yourself into trouble!!!". When properly executed, PPA will allow the attack team to seek and find the fire in "almost ideal" conditions. It greatly reduces heat and smoke, and if in a rescue situation, introduces "clean air" into the structure. This gives any victims, a greater chance of survival by reducing toxic gases and heat, and introducing much needed oxygen into the structure/room.
I strongly urge anyone interested in this topic to hit the website and do the research....it works, and works well when properly executed. TRAIN, TRAIN, TRAIN, before attempting PPA as a tactic on the fireground.
