    CAFS quite simply is one of the best tools we now have in our arsenal.

    It's great for structure protection in wildland interfaces. Saw it firsthand on about 50 homes in the High Meadow fire in Jefferson County Colorado last year.

    There are also numerous products out there like Barricade (rated in my book at about a 9, although this is a homeowner product) I would recommend to any fire department that you show this product to your homeowners groups and residents because you can do a lot in minutes with barricade and a garden hose.

    The Odin weapon foam system is also one of the best systems Ive ever seen.

    There will be a chapter I think on foam and cafs in the new 1051 update for struture protection specialist and structure triage specialist certs. These should be due at anytime.

    Captian Who pretty much sums up why one would want to use class A foam. All I can add is that in just about every instance we would use water, the mixture of .5 to 1% of class A foam has done it better. For instance. I have seen a rooms and contents knocked down and overhauled with about 120 gallons (via the flow meter on the pump). This usually would have taken a few hundred gallons in the past. A few years back we had a dumpster arsonist. With the foam we increased the % and snow coned it We were back in service in no time. No more rekindles either. Overhaul it is great! Had a house with stuff packed to the ceilings and smoldering. Covered it with 1% and it was out. Not even a heat signature on the TIC. That was the proof for me how well it works. Very good wetting agent.

    My advice is if you can afford to use class A foam, then you can't afford to go without it.

    Thanks Larry

    Lets not forget this is A thread about foam not our product. Your comments are welcome in the appropriate thread. Unfortunatly I can not respond on the threads because of the rules, and since you wont answer my e-mails I guess we wont be able to have a proffessional discussion on what our products aplication or applications are.

    We use three different foam systems.

    Our 1995 Engine-Tank has a Hale FoamPro system on it.

    Our 1995 Service truck has a Darley Snuffer CAFS system on it.

    And on our 1978 Engine-Tank we use an old-fashion early 70s era foam eductor, originally for Class B foam. We usually set it at 3%, then take a 5 gallon pail and mix 1 part foam, 9 parts water to make the end result 0.3% foam coming out of it. For that matter, we keep a couple of foam pails we previously emptied filled with the 10% solution (3% of 10% is... 0.3%)

    Our new Ladder being delivered late in May will also have a Foam-Pro handline sized system on it, and a "T" connector on the ladder pipe feed -- so we can run a preconnect around flowing 100gpm of 3% Class A and add it to the T in the prepiped waterway flowing 900gpm water to yield 1000gpm 0.3% Class A. We went with this over having a foam system large enough to directly feed the ladderpipe mainly to save a little money, and since we're more likely to flow handlines with foam than the stick, the smaller handline sized system proportions the foam more accurately at lower flows than bigger systems do.

    We use this stuff called fuel buster. We put it in our tanks and it has worked out quite well. We had a drill with a truck tire that was burning pretty good put this stuff on it and it put the fire out. We have used it for a few years now and had no ill effects. We also have class a foam but we really don't use it because of the fuel buster.

    Many of my clients and home town FD. Feel free to pickup up the phone KEA dial 775 423 4942 and ask The Chief Engineer if they got a pallet of foam, what my role this week has been, what it will be in the future and what it has been in the past. This might be hard for you to understand but there is more to a FD than holding hoses, oh I've done that too in town. Oh, ask if I profit in anyway in my role with the home town FD.

    "We" save money, "we" do a better job. Gee, I saw one of your nozzles on an attack line today, I guess they weren't fully sold, they used other nozzles on all the other lines. Hmmm, something wrong with that thing?? Seems to be a confidence issue, the FD had the $800,000 I got tyhem to spend and couldn't or wouldn't buy enought of your tips to do all the lines. Why is that? Very strange, almost every department equips their rigs with one standard preconnect nozzle on their lines, I guess yours is special. Gosh, everytime they go to the crosslay they have to decide do I dare or don't I. What gives, can't it do the entire job?

    The funny thing even the guys sold on your tip don't put it on more than one line at their paid job. One nozzle at a time is a hard way to make an impact.

    If they are sold on the small nozzle, why not the bigger one and the deck gun tip? It has got to be a trust issue or limited ability, don't you think? The American fire service votes with their pocket books, they aren't buying many of your gig are they? The fire service is full of one of a kind stuff we bought just one of. Not much af a legacy to build.

    An addendum to mu above post:
    I'm not sure what the foam setting was on the CAFS system, but the foam was VERY dry. The dept only had 1 attack truck running with all foam and serveral FF's with Indian Tanks. If we had used our 2500 gals of water from our tanker, plus the 1000 on the other 2 trucks that were sitting idly by, we could've knocked the fire out with just water, and used the foam for protecting exposures.
    As a side note, I think the dept has learned the foam lesson. Today we had anothe brush fire in that town, and not a single drop of foam was applied.

    Class A is great, but you have to know how to use it.

    CAFS is currently the the top of the line tool for its application.

    CAFS is able to operate in 3 modes.

    Compressed Air Foam
    Foam
    Water

    Compressed Air Foam is very limited in a wildland application. If the solution is to dry all the water is held by the bubbles. All this does is block air to the fuel. As the bubbles break down you get rekindle.
    If you need to protect a structure CAFS is great the Dry sticky foam clings to things and reflects the radiant heat. Such as the tank and building mentioned above.

    FOAM- For wildland fires. injected at .1 to .2% this produces very little bubbling but allows the carbon loving component of class A to penetrate and draw the water into the fuel to prolong the cooling effect.
    In the situation above the actual extinguishment of the fire and a fire break ground soak around the base of the tank and the structure.

    Water only. Pretty much anywhere you used any foam. Protection or extinguishment. But you'll need more apparatus and several extra water tenders to do the same job.

    CAFS is establishing a strong place in the industry. We just need to learn when and why we use it.

    Hydraulic tools in Vehicle extrication have made a large difference. But there are times when a recip saw, air chisel or Haligan tool, will do a better and faster job for a given task.

    We don't use a 10lb sledge hammer to drive a finishing nail in a block of wood. The right tool at the right time in the right application.

    I have a question about foam use. Our neigboring town recently had a brush fire, we were called in for mutual aid. When we arrived on scene, the dept was applying foam to the brush fire. The fire was on a hill with small saplings up to about 3' high with sparse taller trees. At the top of the hill(the fire started at the bottom and worked it's way up) was a house with a 500 gal propane tank. My dept's tanker was used to fill the "home" dept's trucks and were relieved when we were empty. Back at the station, we were discussing the use of foam on a brush fire. Wecame to the conclusion that if foam were to be used, it would be used to "secure" the perimeter along with any other objects in the way such as the propane tank, which they did not foam. About 15 min after we were back in service, they called the other dept that was on standby to go to the scene for rekindles. They were on scene just as long as we were for rekindles. Our thoughts on this situation was that if straight H2O was applied in the beginning, the rekindles wouldn't have happpened. When we left, the foam was dissapating, and firelets were popping out. We just rescently took delivery of a new pumper with on board foam and was wondering if foam for initial attack on brush fires is commom. I think the dept uses a CAFS system. This dept also dumped their foam into a portable tank during a tanker shuttle a few years ago

    We use a Class A/B foam with microbes. It is a univeral foam that can be usesd at 1% to 2 tenths. We only pay $7 a gallon or 35 gallons a can, if we buy 8 five gallon cans at a time. It is really good foam. If you want to know where we get ours email me at [email protected] What do you guys pay?

    Hello all,

    I would have to agree with most of the statements made regarding class"A" foam.

    We've been using Class "A" foam for 3 years now in conjunction with CAFS. Our results have been all positive. The basic firefighting tatics of an aggessive interior fire attack remain the same. Just having Class "A" foam or CAFS on the fireground will not put out the fire. You still have to "put the wet stuff (foam solution) on the red stuff", CAFS or otherwise. Class "A" foam enhances water! When applied with CAFS it incredibly enhances water!

    Just a quick comment to IRFD120. Class "A" foam is in no way comparable to high pressure fog. It works entirely different than the way high pressure fog does or dosen't work. It is like comparing apples to oranges.

    And, if you fill a homeowners house with foam during a fire attack, then you are doing something very, very wrong with regards to your your tatics and procedures. When the Class "A" foam is properly applied during an interior attack with CAFS or just class "A" foam through a fog nozzle, there is little foam residue left. It gets absorbed by the class A materials. Class "A" foam is basically soap detergent.

    If your using Class "A" foam for fire attack, your ahead of the others who don't. The only thing that puts you further ahead is CAFS!

    Training and education on the topic of Class "A" foam and CAFS is still the simple solution to the many "questions" and/or "problems" that come up on this subject.

    Good Luck!

    We have had LOTS of positive things happen with the use of foam. try this experiment sometime and see for yourself. next time you guys have a house to burn to the ground and use for training. just before you let er go for good, spray some foam on one or two sides of the exterior walls. as the house eventually collapses, the walls you coated will almost defintley fall last. we've experimented with this trick several times. you may have to reapply foam to it a couple more times though.

    i have seen the foam used looks like awinner but i have been around long enough to also see high pressure fog and where is it now.
    also i have a hard enough time explaining a hole in the roof to homeowners let alone trying to explain why thier house is full of foam

    The main benefit of Class A foam is that it alters the physical properties of water. Class A foam decreases the 'surface tension' of water allowing water to soak into the surfaces increasing cooling. The surface area in contact with water is greater. Water molecules tend to stick to each other resulting in the 'beading' commonly seen on car hoods and stuff. Class A alters that property giving us faster extinguishment with less water. Hope that helps.
