Appendix A
Hazard Assessment and Standard Operating Procedures (SOP) for High Voltage Activities
UC Irvine shall develop and employ work practices and procedures to minimize work involving energized electrical
systems and components. In the event that this increases the hazard(s) or is infeasible, UC Irvine shall utilize work
practices and procedures to prevent electrical shock or other injuries resulting from either direct or indirect electrical
contacts.
The best known method for preventing accidents, injuries, and other incidents during energized electrical work is to
pre-plan the corresponding work and use the appropriate work procedures, tools, guards, personal protective
equipment (PPE), and other controls to minimize the potential for contact with energized electrical circuits. UC Irvine
will develop and implement a written Hazard Assessment and SOP for all High Voltage activities. The Hazard
Assessment and SOP should be written and implemented when a project possesses an exposure or a non-routine
task possesses a hazard.
Qualified High Voltage Electrical Workers must assess the tasks to be performed and note whether the work can be
performed with the equipment in the de-energized state, as described below. The equipment manual, as well as
personnel who are experienced with the equipment, shall be consulted for assistance in making these determinations.
When work on equipment must be performed while energized, follow the procedures for energized electrical work as
described in this program.
When work involves cords and plug-in equipment, follow the cord and plug-in procedures as described below.

electrical work must use
good housekeeping
practices.
Housekeeping - Work
areas should be kept
clean and free of debris
to allow for the work to be
completed safely.
Housekeeping Housekeeping duties
should not be performed
when energized parts
present an electrical
contact hazard, unless
adequate safeguards
such as barriers and
insulating equipment are
provided.
Housekeeping Electrically conductive
cleaning materials (e.g.,
steel wool, metallized
cloth, silicon carbide,
conductive liquid
solutions such as
ammonia, etc.) should
not be used in close
proximity to energized
equipment unless
procedures are followed
that will prevent contact
with the energized
equipment.

performing electrical work
shall not wear conductive
apparel such as:
watches, rings, key

headgear (including
glasses), and other metal
accessories unless
rendered non-conductive
by insulating means.
Conductive
Equipment and
Apparel – All
necessary protective
devices such as insulated
and rated gloves, safety
glasses (nonmetallic and
non conductive), hoods,
and rubber blankets must
be used. Shoes or boots
must be nonconductive.
See Appendix C.
Conductive
Equipment and
Apparel - Conductive
measuring tapes, fish
tapes, ladders or tools
shall not be permitted
when working on or near
electrical equipment.
Conductive

inspection shall be made
of all equipment used for
handling or testing
energized lines or
equipment.

heat, light, and oily
environments.
Signs and Labels Safety signs, tags, labels,
and barricades must be
used during electrical
work to warn persons of
electrical shock and burn
hazards.
Signs and Labels - If
safety signs, tags, and
barricades do not provide
sufficient warning about
electrical hazards (e.g.,
an electrical interlock
removed from an AC
distribution box with
voltages above 600
volts), an attendant shall
be stationed to warn
employees and restrict
access.
