在第二次世界大战期间,美军在向士兵作“这里有危险”、“禁止入内”等指示时。为了简明扼要,便出现了安全色标的最初概念。在1942年,美国一家著名的颜料公司统一制定了一种安全色彩的规则,广泛地被海洋、杜邦公司和其他单位应用。随着工业、交通的发展,一些工业发达国家相继公布了本国的“安全色”和“安全标志”国家标准。 During the Second World War, the U.S. military made “dangerous here” and “no-entry” directives to soldiers. For the sake of conciseness, the first concept of a security color code appeared. In 1942, a well-known American pigment company unanimously developed a safe color rules, widely used by the ocean, DuPont and other units. With the development of industry and transportation, some industrialized countries have successively promulgated their own national standards of “safe color” and “safety sign”.
