b. Clothing.- Workmen on the insulating ladder shall be completely clothed in
conductive clothing designed for barehand work. Workmen on steel towers shall also
wear conductive footwear.
c. Bonding.- Before beginning work, workmen shall bond their conductive clothing to
the energized circuit. Additionally, if two workmen are involved at the same work
location on an insulating ladder, they shall bond their clothing to each other.
d. Rigging.- Before a workman is allowed on the insulating ladder, the crew foreman
must first make sure that all rigging is complete and secure.
e. Passing Objects.- Objects that are to be passed by hot stick to the workman on
the insulating ladder shall be passed only after he or she is bonded to the energized
circuit. These items shall not be passed directly to the workman, but shall first be
touched to the energized circuit.
f. Safety Straps.- Except when mounting or dismounting the insulating ladder,
workmen shall maintain their safety straps around the insulating ladder at all times.
Insulating ladders shall be equipped with nonconductive safety ropes along the rails.
The use of ladder snaps on the safety straps is required. Workmen shall be snapped
to the insulating ladder when they are in a working position and when the insulating
ladder is being moved.
4.3.4 Structure-mounted Ladders. The following additional requirements shall be
observed for structure-mounted insulating ladder operations:
a. Securing Ladder.- One end of the insulating ladder shall be positively secured to
the structure, either by clamps or safety chains. Neither the energized end of the
insulating ladder nor the workmen shall be solidly clamped or tied to the conductor,
insulator string, or other suspended component when a known defect exists or when
the suspension devices or connectors are begin worked on.
b. Control of Ladder.- Positive movement control of the insulating ladder shall
normally be provided from the structure or ground, using hot sticks and/or
nonconductive rope. The control equipment shall provide a positive means of moving
workmen on insulating ladders a safe distance away from any energized feature.
Sufficient personnel shall be provided on the structure on or the ground to
adequately handle and control the insulating ladder. The insulating ladder shall be
moved to a safe deenergized position prior to permitting workmen to mount or
dismount it. Under certain conditions, where work is on other than the conductor or
suspension devices, workmen on the insulating ladder may use a hot stick attached
to the energized conductor or other energized part to help guide them to
