  • 3%-6% foam in water extinguishers

    Just curious how many departments use 3%-6% foam in "water" extinguishers? Now, I'm not talking about extinguishers marked on the label "Water or Foam", I'm talking about pouring the foam in the water extinguisher and mixing it with water.

    I've seen this done, and wondered if anyone has had any problems with the extinguishers.

    Thanks

    We have used a product called Fuel Buster in water extinguishers for about 4 years. We mix 1 quart in a 2 1/2 gal water extinguisher. It has worked great on small fires.

      Flochief,

      Any problems with damage to the extinguisher itself from the fuel buster product? Pitting? Corrosion?

        Sometimes......

        When things are really dry, and we get woods fires that start to dig in deep into the moss, roots, Etc. we add a cup of liquid detergent to a 2 1/2 gal. water can. Works well if all you need is penetration. Never had a problem that I am aware of.... Stay Safe....

          When we refill APW extinguishers, we dump a small amount of Class A from a bucket sitting around the station. Same stuff we use on the trucks.

              Like hwoods, we do the same thing in our forestry back packs.Pour about 1 1/2 cups of 3% into the reservoir and fill.It penetrates better and we've had no problems.

                I put a cup of foam in a 2.5 gal pressure water extinguisher that I keep in my car. It works alot better on car fires than a 20# dry chem. If you don't have foam, dishwashing liquid works almost as well. I recommend Dawn since it cuts grease & petroleum products really well.

                Only suggestion: put the foam/detergent in AFTER you've put in the water.

                    We now use a product called FIREAID2000. It is mixed with water in the can and labled as such. In our other water extinguisher we put our F500 foam (Class A and B rated).

                    The fireaid2000 stuff I have not yet seen used in the field, but the marketing video claimed one 2 1/2 gallon water extinguisher with the stuff mixed in is enough to put out a fully involved car fire. I'll believe that when I see it, but they did do it in the video ...so who knows. It is supposed to have a "rapid cooling effect". the Jury is still out on the thermodynamic principles behind that, but, if and when we use it (We have only had the stuff for about 2-3 months now) I'll post results.

                    Hey, if the stuff gives the water a lot more penetrating power, it's a force multiplier so what the heck. The way I see it, you can work a lot or, you can work smart. Choose wisely.

                      Most of these additives work real well. From an investigation standpoint, make sure you keep a copy of the MSDS around so the investigator knows what materials have been added to his scene if the ext. has been used on a fire that is being investigated.

                      There is at least one of these additives that uses a small amount of kerosene it.

                          3% -6%

                          I don't suppose it is really either 3, or 6%, unless the ratio is right, right!

                            Mix Ratio..........................

                            You can work out what you need for your area, or the type of Fire that you're going after. A cup of liquid detergent is not the same as a 3% or 6% AFFF mix. Class A fuels, Brush Fires in particular, Liquid Detergent works well at one cup (8 ounces) to 2.5 gallons of water, and that is about a 2% Ratio. I'll get the Foam salesmen upset, but Liquid Detergent is Cost Effective when compared to class A foam, by about a 3 to 1 margin, 5 Gallons of Liquid detergent @ $4.00/Gallon is $20.00 compared to Class A Foam at $80.00 for a 5 gallon Pail. BUT, you do not get the Foam effect from Detergent, it is generally used as a wetting agent only, real Foam is for Blanketing, Etc.

                              We use AFFF (10 oz I think) in water cans on all trucks and some engines. Generally used for oil burner fires. HAZMAT companies also carry some other products premixed in water cans such as biosolve.
