The fiberglass boom and platform liners must be dielectrically tested periodically to
insure the insulating properties are being maintained.
Do not assume that it is so.
Ground personnel must be warned to stay away from vehicle in case of accidental boom
contact between conductor and metallic portion of boom, which will cause serious injury
or death.
The fiberglass upper boom, fiberglass lower boom insert and fiberglass platform,
including its components, do not protect the platform operator from injury in case of
contact between two energized lines or between an energized line and a grounded
conductor.
Upper Controls can become energized if any part of the boom-tip past the band of arrows
on the boom contacts a conductor. The Aerial Device upper control station has metal
parts that are necessary to provide the structural support for the components. These
metal parts at the boom-tip are interconnected. The main shaft that supports the
platform(s) and controls also support other load carrying options that can be added to the
boom-tip.
Do not depend on Aerial Device covers for insulation. Plastic or fiberglass covers offer
limited electrical insulation. Covers are not tested, certified or maintained as insulation.
All conductors including grounds and neutral lines are current carrying conductors and
must be treated as energized unless properly grounded and tested.
The fiberglass upper and lower boom, in a well maintained condition, provides electrical
insulation between the upper boom-tip and the vehicle to ground. This fiberglass will not
protect the platform operator if any portion of the boom tip or upper arm control station,
including options is brought into contact with an energized or non-energized conductor
and the operator is in contact with a different potential, such as grounded non-energized
conductor. This type of contact can energize or ground the controls because all
components of the upper control station are interconnected. The fiberglass will not
provide protection for the operator in phase to phase contact or a phase to ground wire
contact above the upper boom insulation. Nor will it protect the vehicle from becoming
energized if the steel boom section below the lower boom insert, if so equipped, is
brought into contact with an energized conductor. Serious injury or death could result.
