The equipment, by design, cannot be shut down 

The decision to work without de-energizing shall be made by management and
documented before work begins
When any employee is exposed to direct or indirect contact with parts of fixed electrical
equipment or circuits that have been de-energized, the electrical energy source will be locked
out.
Energized Parts
If work must be performed while equipment is energized or if de-energizing is not feasible,
additional safety measures will be taken to ensure the safety of the qualified employee and
any other persons who may be exposed. Protection from energized parts will be suitable for
the type of hazard involved. Exposed energized parts in areas accessible to the public shall be
continuously protected by an authorized attendant. In areas not accessible to the public,
employees shall be protected from exposed energized parts by the use of signs or tags. In
addition to signs or tags, barricades shall be used where necessary to limit access to areas
with exposed energized parts.
Only Qualified persons will be allowed to perform work directly on energized parts or
equipment. Qualified persons will be capable of working safely on energized circuits and will
be familiar with special precautionary techniques, personal protective equipment, insulating
and shielding materials and insulated tools. Qualified persons must also have received the
training required in this safety procedure.
Illumination
Employees will be provided with adequate light to work on energized equipment or
equipment will be relocated to ensure adequate light is available.
Portable Ladders
Portable ladders will have nonconductive surfaces if they are used where the employee or
the ladder could be exposed to electrical shock hazards.
Reclosing Circuits
If circuits are tripped using a protective device such as ground fault circuit interrupter (GFCI),
power will not be restored until the reason for the interruption is determined and corrected.
Fuses or breakers will not be replaced or reset until it is determined that the circuit is safe to
operate. Fuses will not be replaced with higher rated fuses or with makeshift devices to
bypass circuit protection as designed. Problems will be identified and promptly repaired by a
qualified person.
Vehicular and Mechanical Equipment Near Overhead Power Lines
Overhead power lines will be de-energized and grounded before any work is performed by
any vehicle or mechanical equipment near the energized overhead power lines. If the
overhead lines cannot be de-energized, then the vehicle or mechanical equipment will be
operated so that a clearance of 10 feet is maintained. If the voltage of the overhead line
exceeds 50 kV, the distance will be increased 4 inches for every 10 kV increase in power. If
