Abstract
A method of proportioning a finished foam at or near a hazard comprising proportioning and delivering a first finished foam to the hazard, determining if the first finished foam extinguishes or suppresses the hazard, if not, selecting an amount of a fluorinated additive, and proportioning a foam solution including the selected amount of the fluorinated additive to form a fluorinated finished foam. A foam injection system is also disclosed.
Claims5
A method of proportioning a finished foam, the method comprising:
- a) foaming a stream of a first foam solution to form a first finished foam, and delivering the first finished foam on a hazard;
- b) selecting an amount of an additional fire suppression additive;
- and
- c) adding the selected amount of the additional fire suppression additive to the stream of the first foam solution to form a modified foam solution stream.
A method of forming a fire fighting foam comprising:
- a) diluting a base foam concentrate with a stream of dilution water to provide a first foam solution stream;
- and foaming the first foam solution stream to provide a first finished foam;
- b) modifying the first foam solution stream to include a selected amount of an additional fire suppression additive to form a second foam solution stream;
- and
- c) foaming the second foam solution stream to form a second finished foam.
