Marine portable chemical applicator

A portable chemical foam applicator for shipboard use comprising:

• foam generation apparatus including a self-educting nozzle for mixing water and foam concentrate to produce foam for application to a fire;
• a unitary vest having a frontal opening enabling a fire fighter to don the vest from the front, the vest being continuous across the back, sides and those portions of the front located laterally outwardly of the margins defining the frontal opening, the vest including a unitary internal bladder for holding foam concentrate, an internal discharge hose extending around the interior of the bladder and connected to a discharge port in fluid communication with the nozzle, the hose having a plurality of openings along its length whereby foam concentrate may be drawn by the by self-educting nozzle from the bladder and through the hose openings for subsequent mixing with water in the nozzle to produce the foam, the vest being fabricated of a single sheet of material folded along its middle to define an outer surface of fire resistant material and an inner surface defining the bladder, the folded sheet being fabricated to form arm holes in the folded sheet, the margins of the folded sheet being bonded to render the bladder leakproof, the vest further including relatively narrow, vertically extending and laterally spaced apart bonded areas joining the interior of the front and back of the vest, the bonded areas preventing ballooning of the filled vest, and also reducing rapid lateral displacement or sloshing of the chemical concentrate in the vest which might otherwise result in an unexpected change in the center of gravity of the contained concentrate.
