WHAT IS INSULATED AND WHAT IS NOT INSULATED
The term insulated means separated from other conductive surfaces by a dielectric substance (including air
space) offering a high resistance to the passage of current (from OSHA 1926.960).
Area A.
Upper Boom Insulation, provides an insulating area between area D and earth ground when in
properly maintained condition.
Area B.
Lower Boom Insert, provides an insulating area between area C and area E when in properly
maintained condition.
Area C.
Elbow, does not provide insulation. This area contains conductive materials such as cylinders, pins,
boom structure, and other metal components. The operator shall not allow any portion of this area to come
in contact with an energized phase, ground conductor, or grounded objects. Proper protective devices shall
be used on all conductors. Any contact with a ground and phase line or between two-phase conductors will
create a hazard.
Area D.
Boom Tip, does not provide insulation. This area contains conductive materials such as control
levers, un-insulated platform(s), platform support shaft, boom-tip structure and other metal components.
These objects must be considered connected. The operator shall not allow any portion of this area to come
in contact with an energized phase, ground conductor or grounded objects. Proper protective devices shall
be used on all conductors. The operator shall not make contact with any portion of this area when working
on or near an energized phase, ground or grounded objects, unless wearing proper protective clothing such
as rubber gloves and sleeves rated at the voltage of the lines. Any contact with a phase line, a ground and
phase or between two-phase conductors will create a hazard. Accidental contact of any portion of area D to
an energized conductor will energize the entire area D.
NOTE: A properly maintained platform liner will only provide protection for those portions of the
body or materials entirely within the liner and not in contact with any part of area D.
Area E.
Does not provide insulation. This area contains conductive materials such as cylinders, pins, boom
structure, turntable, pedestal and other metal components. The operator shall not allow any portion of this
area to come in contact with an energized phase, ground, or grounded objects. Proper protective devices
shall be used on all conductors. This area is attached to the vehicle and connected trailers, which must be
barricaded and/or grounded through an approved ground system when working in the vicinity of energized
conductors. Any contact with a phase or between two-phase conductors will create a hazard.
