Foreword In early January 1981, several member companies of the NEMA Transformer Section indicated a strong desire to reduce the number of accidents involving children coming into contact with the active elements of pad-m
5、ounted transformers located in public areas. These accidents, while statistically low in number per year, are usually disfiguring and can result in death. In February 1981, the Power Equipment Division Executive Committee established the Task Force on Safety Labels for Pad-mounted Switchgear and Tra
6、nsformers Sited in Public Areas. The Executive Committee charged the Task Force to develop a safety label which would warn small children away from an open pad-mount and simultaneously elicit an adults attention to contact the owner of the pad-mount to remove the hazard. The Task Force was also inst
7、ructed to develop a standard to accompany the label which would define its scope, content, appearance, and construction. Over a period of 14 months, the Task Force pursued a liaison with manufacturers and user groups in order to obtain acceptance of the safety label concept while label development w
8、as underway. The resulting pictorial, “Mr. Ouch,“ was developed from several designs and was psychologically tested in two phases. In the fall of 1981, 16 possible pictorials were tested in Chicago, Illinois and San Antonio, Texas, among an equal number of English and non-English speaking children a
9、ged 2-1/2 to 6. Phase I testing indicated no significance in geographical considerations regarding the perceptual attitudes of the children. The best four pictorials of Phase I testing were redesigned and tested again in January 1982 among English and non-English speaking children aged 2-1/2 to 6-1/
10、2 in Chicago, Illinois. In Phase II testing, the “Mr. Ouch“ pictorial scored very high in the two major desirable label attributesthe depiction of an immediate hazard and the elicitation of a safe response from the child to avoid the hazard. The psychological testing was conducted by the George R. F
11、raich Associates Testing Organization of Chicago, Illinois. Graphic design was provided by Agnew Moyer Smith Inc., Pittsburgh, Pennsylvania. This revision of the standard was undertaken to make editorial changes to the standards text and figures. NEMA has exclusive rights for the management of the “
