How to check a shower without taking one is accomplished by special shower tester used in the General Electric Company's Research Laboratory. Showers are installed at strategic points in workrooms of the laboratory to douse a scientist in case his clothes catch on fire or in event of acid burn. Although they rarely are used, showers have to be in working order and are checked periodically. Devised by Howard H. Fawcett, Laboratory safety engineer, special tester permits water from shower to be squirted into a large funnel, from which it is carried into a can. A hose conducts the water to a nearby sink.
