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 system are in a larger collecting pool created by placing a large plastic sheet over a fire hose in a closed loop on a flat surface . a person is moved through successive stations of one set with the first station having soap selectively added to the spray by a controlled mixing device connected to the manifold . all rings , telescoping handles and a manifold for one two - set system may be packed as a kit in a single flat square bag .
