We use Class A and B foam all the time in Australia. Our agency uses Class A (We call it B-Tripple-F (Bush Firefighting Foam) and it's incredibly versatile. We do run a Foam proportioning system on most of our units though. 6% for mop-up all the way down to .25%.
Great video Dave! I can't think of a time I've ever used foam on a field fire and it's most likely because water is "free". Great examples though. Thanks
Your math is wrong. 1% of 100 gallons is 1 gallon...not because you dropped the .28....you meant to say 1.28 ounces of foam per 1 gallon or 128 ounces per 100 gallons
You DON'T want a foam "blanket" on class A materials, you want it to soak in. Using too much class A will make a blanket that will sit on top of materials like mulch and sawdust, and the fire will just smolder underneath. Remember that with Class B foam, we are separating the fuel from air. With Class A fires, there is already air mixed in with the fuel, and often it can draw more air in from underneath or from the sides. Just a few fine bubbles on the top in a thin layer is just about what you want. A thick blanket like what you would use on a Class B fire is not helpful. You want the foam concentrate to enable the water to soak into every little nook and cranny. Using a higher percentage than what you need is also wasteful.
Rick1885 Have my own type 1 engine with 750gals of water, and dual foam. Mostly to protect my own property. Have put out several neighborhood fires over the years. I'm surprised more people don't have their own fire trucks.
***** Well, I ran class A foam at 0.5% instead of my usual 1%. Still made great foam at the lesser concentration. Now I can foam the backyard twice as often.
@@rleslie845 I couldn't agree more. Used fire engines are surprisingly cheap, are usually meticulously maintained and have amazingly low miles. We live on acreage in wildfire area so we bought our own Type 6 engine with 300 Gal tank and foam system. We have a 16' walmart/coleman pool which holds about 5500 Gal that we use for extra water supply. Our primary use for foam would be preventative to wet things down or foam them up ahead of an advancing fire so we don't have to fight things that are on fire.

Our depts use class A foam on wild land fires for sure as we get a lot of them and we need to conserve water.
Hey, I think that is our old engine in the background. Engine 14-1 out of Lebanon , Pennsylvania (Neversink Fire Company)
will this attach to a 3/4" garden hose?
Awesome vid! Thanks!
love this vid in billions of ways
Didn't realize 0.5% is as effective as 1%.
I'll have to do some trials with my private engine.
You have a private fire engine?

It seems pretty logical to me to own an engine.
I'm in Southern Calif No shortage of fires and earthquakes.
And I was told by a UTubr that foam was a waste on grass fires.
