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.
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.
