Purpose
When it is necessary for Jefferson
Lab to build or modify electronic
equipment, including AC utilization equipment, it is done in compliance in
accordance with “10
CFR 851 – Worker Safety and Health Program.” This is
achieved by assuring that final products meet the intent of applicable
electrical safety standards and are maintained in a safe working condition. This
chapter defines the practices used to achieve this goal.

Scope
This
chapter and its associated appendices, applies to the construction and
modification of electronic equipment at Jefferson Lab. Items that have not been altered, and are recognized by a Nationally
Recognized Testing Laboratory-NRTL (e.g.: those that are UL listed), are not
included within the scope of this document.
Equipment that is
built in compliance with an appropriate industry standard is documented
in accordance with department procedures. The guidelines in this chapter define
minimum design considerations that reduce hazards and incorporate engineering
safeguards.
