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-mounted ransformers 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 Transformers 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 adult's 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 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 was underway. The

resulting pictorial, Mr. Ouch, was developed from several designs and was psychologically ested 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 aged 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 2-112 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-the depiction of an

immediate hazard and the elicitation of a safe response from the child to avoid the hazard.

The psychological esting was conducted by the George R. Fraich 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 standard's text and figures.

NEMA has exclusive rights for the management of the Mr. Ouch pictorial. Rights may be obtained for the

use of the pictorial from the National Electrical Manufacturers Association, Suite 1847, 1300 North 17th

Street, Rosslyn,

VA 22209.

the standard does not necessarily imply that all section members voted for its approval or participated n its

Purpose

These labels are intended to identify pad-mountedequipment as potentially hazardous to anyone who

comes in contact with its contents. The pictorials are designed to be meaningful

o

children and the

illiterate and

to

contain supportive wording expected to elicit a safe response from an adult.

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 normally accessible to the general

public.
