Patent ID: 7832492

Claim:
A method of fighting vegetative fires including forest and brush fires, comprising the steps of: deploying by transporting, to a desired site of a fire break, portable firefighting equipment comprised of at least two lengths of releasably couplable conduit with each conduit having a plurality of apertures, a high pressure high fluid flow rate pump which generates an output pressure of 200 psi to 600 psi and an output fluid flow rate of between 200 and 1000 gallons per minute and a conduit closure; creating a fire break by wetting an elongated area of ground with a fire retardant fluid and creating a spray of fire retardant fluid upwardly directed; said wetting and creating a spray steps including the steps of: laying out on the ground said at least two conduits each with an internal cross sectional area of at least 1.75 square inches and with each conduit having at least one row of apertures centered on a plane substantially perpendicular to the ground on which said conduit is laid; releasably coupling together said at least two conduits; applying said closure to one end of said coupled conduits; providing as a part of said portable firefighting equipment means to inhibit longitudinal rotational motion of said conduit; supplying a fire retardant fluid to said site and supplying it to said high pressure high fluid flow rate pump; and forcing by said high pressure high fluid flow rate pump said fire retardant fluid into said conduit and out of said apertures at a rate of at least 200 gallons per minute to wet the longitudinal area and to create a spray of fire retardant fluid to create a fire break to impede or stop a vegetative fire.
