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.
This Standards Publication was developed by the Switchgear and Transformer sections. Section approval of
the standard does not necessarily imply that all section members voted for its approval or participated n its
development. At the time it was approved, the Group/Section was composed of the following members:

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.
