14、anies 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-mounted transformers located in public areas. These accidents, while statistically low in number per year, are usually disfiguring

15、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 Transformers Sited in Public Areas. The Executive Committee charged the Task Force to develop a safety label which would warn small c

16、hildren 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 instructed to develop a standard to accompany the label which would define its scope, content, appearance, and construction. Over a pe

17、riod 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 was underway. The resulting pictorial, “Mr. Ouch,“ was developed from several designs and was psychologically tested in two phases.

18、 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 aged 2-1/2 to 6. Phase I testing indicated no significance in geographical considerations regarding the perceptual attitudes of the

19、 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 2-112 to 6-1/2 in Chicago, Illinois. In Phase II testing, the “Mr. Ouch“ pictorial scored very high in the two major desirable label attributes

20、-the 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. Fraich Associates Testing Organization of Chicago, Illinois. Graphic design was provided by Agnew Moyer Smith Inc., Pittsburgh, Pe

21、nnsylvania. 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 “Mr. Ouch“ pictorial.

31、 GENERAL 1.1 SCOPE These labels are for use on pad-mounted switchgear and transformers sited in public areas, such as utility easements adjacent to residential properties, shopping centers, schools, etc. They may also be used for such equipment sited in utility or industrial properties which are not

32、 normally accessible to the general public. Section 2 MATERIAL 2.1 The labels shall be durable and made of weather resistant material. 2.2 or destroying them. These labels shall meet the requirements of UL 969-1982, Marking and Labeling Systems. Adhesive mounted labels shall be such that removal is

33、impossible, except by defacing, covering, 2.3 Labels mounted by mechanical fasteners shall be used only if the removal of the mechanical fasteners leaves the cabinet with no openings through which foreign objects-such as sticks, rods or wires-mi ht be inserted to contact live components. These label

34、s shall meet the requirements of UL 969-1 982 listed below: 9. Requirement Reference (of UL969) Legibility test Table 4.1 Defacement test Table 4.1 Humidity test Paragraph 8.3 Temperature test Paragraph 8.4 Ultraviolet light test Paragraph 8.5 Section 3 MAINTENANCE 3.1 it is attached. Renewal of the

35、 safety label may be required during normal maintenance. The safety label should remain legible for the service life of the pad-mounted equipment to which This standard is available from Underwriters Laboratory, 333 Pfingsten Road, Northbrook, Illinois 60062 * UL969-1982 is written for adhesively mo

36、unted labels. However, some requirements are appropriate for labels mounted with mechanical fasteners. These latter requirements have been extracted for incorporation in this standard. 260-1 996 Page 2 Section 4 FORMAT 4.1 field shall be red. All label colors depicted in Figures 4-1 through 4-4 shal

37、l conform to the following Munsell Notations: The color of the warning signal word field shall be orange, and the color of the danger signal word Black Oranae I 5.0 YR 6.0/15 I N - 2.0 or lower 1 White I N - 9.0 or higher 1 4.2 The safety labels in Figures 4-1 and 4-2 shall be standard and shall be

The danger label (Figure 4-2) shall be affixed to the inside of the pad-mounted equipment. 4.3

39、 These labels shall be 10.6 inches, -0.0 inches + 1 .O inches (26.92 cm. -0.0 cm, + 2.54 cm) wide, with the height being variable to accommodate the bilingual message. As an option, bilingual labels, such as Figures 4-3 and 4-4, shall be furnished when specified. 4.4 The owners of the pad-mounted eq

40、uipment should preferably be identified with more information than “immediately call the electric power and light company.“ To this end, the owners of the pad-mounted equipment may place their name, company name, and/or telephone number on, or immediately adjacent to, the area which reads “electric

41、power and light company.“ The preceding standard messages shall not be covered by the substitution, and the material used to convey the ownership of the pad-mounted equipment shall meet the material requirements of this standard (if not printed on the NEMA label).
