Confining Fire
Foam retardants
Foam retardants can be applied on a fireline just prior to fire initiation. They are excellent fire confinement tools, but they have the drawbacks of an additional crew and special equipment.Some advantages of using foam over water and chemical retardants are that (1) foam expands the amount of water available and extends a given water supply 3 to 10 times, (2) it incorporates the characteristics of a wetting agent, (3) it has smothering and insulation effects, and (4) foam is more persistent and visible than water.
