Allow for platform movement, electrical line sway or sag and beware of strong or gusty winds.
Keep away from the machine if it contacts energized power lines. Personnel on the ground or in the
platform must not touch or operate the machine until energized power lines are shut off.
Do not operate the machine during lightning or storms.
Do not use the machine as a ground for welding.
Keep clear of live electric conductors.
Energized Conductor Contact Hazard
When working in the area of energized conductors the user shall direct and the operator shall comply
with the requirements to:
Stay at least 10 feet away from power lines with any part of their body, conductive object or any
part of the MEWP.
If work requires working nearer than 10 feet, stop and consult a qualified person with respect
to electrical transmission and distribution to have appropriate measures taken (such as de-
energizing and grounding).
If there is a question that the power lines may carry more than 50kV, consult a qualified person
with respect to electrical transmission and distribution before proceeding.
If working or approaching closer than explained above, it shall only be done by a qualified
person with respect to electrical transmission and distribution. Only qualified persons may
work on electric circuit parts or equipment that has not been de-energized. Such persons shall
be capable of working safely on energized circuits and shall be familiar with the proper use
of special precautionary techniques, personal protective equipment, insulating and shielding
materials and insulated tools.
