This poster, with its graphic illustration of the difference between safe and unsafe clothing on the factory floor, was produced by the National Safety Council, apparently in collaboration with C.J. Gerhart, then a superintendent at Westinghouse Electric and Manufacturing Co., headquartered in East Pittsburgh. This vast operation began to turn to wartime production in 1940 as the government filled orders from Allied nations fighting Nazism in Europe; the firm ultimately played an important role in the U.S. war effort, making critical developments in the fields of plastics, X-rays, radar, bombsights, and atomic energy. It also built improved power plants for naval vessels and the first American-designed jet engine. The diagram here, showing the hazardous clothing on a bright red ground and the safe, streamlined outfit on a sober black one, clearly communicates the risks to factory workers, many of whom would have been civilians entirely new to this risky kind of work.
