Overhead Line Work
Use of Aerial Lifts
1910.67(c) and 1910.269(p) contain specific
requirements for aerial lift equipment commonly used in overhead line work.
Among these requirements are:
Overhead Line Work
- Equipment can only be operated by trained workers and within equipment
rating and design limitations.
- Personnel working in an aerial lift must wear fall protection and cannot belt
off to a pole or other structure.
- The lift controls of bucket, derrick, and pole setting trucks, etc. must be
tested before use each day to be sure they are in safe working condition.
||See: 1910.67(c) on vehicle-mounted elevating and
rotating work platforms
1910.269(p) on Mechanical Equipment
- Critical safety components that affect raising, lowering, or rotating of lifts
must be visually inspected before use on each shift for indications of any
- When other workers are present, vehicles must not be backed up unless (1)
the driver has a clear rear view and the vehicle has a back-up alarm or (2)
another Worker serves as a guide.
- If a vehicle has outriggers, they must be used unless the work area or terrain
prevents their use. Vehicles may only be used within their maximum load limits
and without outriggers if the manufacturer's design and instructions indicate
that it is safe to operate without the outriggers.
- Before outriggers are set, the operator must have a clear view of the
outriggers or otherwise ascertain that all workers are clear of outrigger
Several of the proposed fall protection design and use requirements apply to
users of aerial lifts. See the proposed rule for additional information.
- When a load is suspended from a boom, operators must remain at the controls
unless it can be shown that there is no hazard to personnel, such as those
created by a falling load, wind, or unstable soil.
- When operating near energized lines or equipment, aerial lift equipment must
maintain the minimum approach distance unless the insulated portion of the
aerial lift is operated by a 269-qualified employee. If necessary, another worker must be a spotter for the
operator to ensure the minimum approach distance is maintained.
If the aerial lift could contact energized lines, then at least one of the
following must be done (see 1910.269(p)(4)):
- The energized lines exposed to contact must be covered with insulating
protective material that will withstand the type of contact that might be made
during the operation; or
- The aerial lift must be insulated, and uninsulated portions of the lifts must
maintain the minimum approach distance from live parts. The aerial lift must
also be positioned so that uninsulated portions of the lift cannot come within
the minimum approach distance from the live parts. (Note that insulated booms
require electrical testing at voltages and intervals specified in ANSI A92.2. An
untested boom or one that fails a test is considered non-insulating. See 1910.67(c)(3)); or
- Workers must be protected by implementing all of the following:
- Each piece of equipment (trucks, trailers, etc.) must be grounded.
- All pieces of equipment must be bonded together.
- Ground mats must be used around equipment to extend the equipotential zone.
- Insulating protective equipment or barricades must be used around the equipotential zone.
