Abstract
A decontamination system for rinsing hazardous materials from victims or suited emergency personnel using hand held thin flat octagonal rings of square aluminum tubing having a plurality of radially inwardly directed nozzles for simultaneously spraying water inwardly toward all sides of the part of a person at the center of the ring in a pattern from each nozzle which is wide but confined to about the thickness of the ring. Each ring has two external diametrically opposed sockets for receiving telescoping handles for spraying movement by one or two assisting persons, or it may be manipulated by a user for self-spraying by being hand held or by being pulled down around the user from an elevated horizontal position in which it is supported by elastic cords within a tent frame structure. Multiple rings for a method of decontamination spraying using a system having two different sets of multiple stations, reserved for emergency personnel and for victims, receive individually controlled supplies of water from one manifold having a single female inlet connector fitting different sizes of fire hose. Each spray station has a separate collecting receptacle and all stations of the two-set sy…
