ENERGIZED FACILITY MAINTENANCE
FIST Volume 3 - 29
Section 1. Energized Facility Maintenance - General
1.1 Definitions
Insulating - Used to describe a material made up solely of insulation
(dielectric substance offering a high resistance to the flow of current) or that
part of a device that provides the insulation.
(dielectric substance offering a high resistance to the flow of current) or that
part of a device that provides the insulation.
Insulated - Separated from other conducting surfaces by a insulating material.
1.2 Scope
This volume is written to provide procedures for operating equipment near energized
equipment, hotstick work, live-line barehand work, and insulated tools for low voltage
work. Previously where hot work was authorized on energized circuits or apparatus
between 600 and 5,000 volts, rubber gloves, linemen's protector shields, hose,
rubber blankets, etc. were used. Because of the problems of personnel training,
maintaining, and testing these rubber goods, Reclamation no longer uses rubber
goods for energized facility maintenance. Personnel using techniques covered in
this FIST on equipment rated 600-volts and above shall be trained in Power System
Clearance Procedures, FIST Volume 1 - 1; and depending on the type and use, as
detailed in subsequent sections, specialized training, testing, and certification may
be required.

Much of the material contained herein was in sections 8 and 9 of the superceded
Power Systems Safety Standards. Some material from section 14 is also included.
This material was intentionally left out of Reclamation 0 & M Safety Standards
because it was felt that it contained too much specialized information that was in
general not applicable to most O&M employees.

1.2.2. Hotstick work is generally limited to measuring distances between an
energized conductor and ground or another energized conductor, using a hotstick-
held clamp-on ammeter, testing a conductor (buzzing) to determine if it is
