The aerial platform is not electrically insulated. Death or serious injury will result from contact
with, or inadequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach distance as dened by the Minimum Safe
Approach Distance section in Chapter 3–Safety.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, scissors structure, or any part of the aerial platform contacts a high-voltage electrical
conductor, the entire machine can become electrically charged.
If that happens, remain on the machine and do not contact any other structure or object. This includes
the ground, adjacent buildings, poles, and any other objects that are not part of the aerial platform.
Such contact could make your body a conductor to the other object, creating an electrical shock hazard
resulting in death or serious injury.
If an aerial platform is in contact with an energized conductor the platform operator must warn ground
personnel in the vicinity to stay away. Their bodies can conduct electricity creating an electrical shock
hazard resulting in death or serious injury.
Do not approach or leave the aerial platform until the electricity has been turned off.
Do not attempt to operate the lower controls when the platform, scissors structure, or any part of the
aerial platform is in contact with a high-voltage electrical conductor or if there is an immediate danger
of such contact.
Personnel on or near an aerial platform must be continuously aware of electrical hazards, recognizing
that death or serious injury can result from contact with an energized conductor.

platform. For example, use two hands and one foot when
climbing into the platform.
While operating the aerial platform, a good safety prac-
tice is to have qualied personnel in the immediate work
area to:
y Help in case of an emergency
y Operate emergency controls as required
y Watch for loss of control by platform operator
y Warn the operator of any obstructions or hazards that
may not be obvious to them
y Watch for soft terrain, sloping surfaces, drop-offs, etc.
where stability could be jeopardized
y Watch for bystanders and never allow anyone to be
under, or to reach through the scissors structure while
operating the aerial platform
Make sure the area below the platform is free of personnel before lowering.
Keep both feet positioned rmly on the platform oor.
Do not dismount while the aerial platform is in motion or
jump off the platform.
Properly stow the aerial platform and secure it against
unauthorized operation at the end of each work day,
before transporting, or if it is left unattended.
Tip-Over and Falling Hazards

Do not climb on the guardrails or use ladders, planks,
or other devices to extend or increase the work position
from the platform.
Take care to prevent rope, electrical cords, and hoses,
etc., from becoming caught in or on the aerial platform.
y If the platform or scissors structure becomes caught
on an adjacent structure or other obstacle and is
prevented from normal motion, reverse the control to
free the platform.
y If control reversal does not free the platform, evacuate
the platform before attempting to free it.
It is best not to transfer from the platform to another
structure or from the structure to the platform, unless
that is the safest way to do the job. Judge each situation
separately taking the work environment into account. If
it is necessary to transfer from the platform to another
structure the following guidelines apply:
1. If you are using a fall restraint, transfer your anchorage from one structure to the other before stepping
across.
Chapter 3 – Safety
3. Use the platform entrance, do not climb over or
through the guardrails.
Electrical System
Charge the batteries in a well-ventilated area free of
ame, sparks, or other hazards that might cause re or
explosion.
Do not operate any of the aerial platform functions while
the battery charger is plugged in.
Warning
Batteries give off hydrogen and oxygen that can com-
bine explosively. Death or serious injury could result
from a chemical explosion. Do not smoke or permit
open ames or sparks when checking the batteries.
Battery acid can damage the skin and eyes. Serious
infection or reaction could result if medical treatment
is not given immediately. Wear face and eye protec-
tion when working near the batteries.

The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a tip-
over accident. Do not position the aerial platform for
elevated use within 4′ (1.2 m) of any drop-off, hole, or
other tip-over hazard.
Note
The lower controls override the upper controls. If the upper control emergency stop button is engaged, the lower
controls can still be used to operate the aerial platform.
At the upper controls, the emergency stop is a two-position red push button (refer to Figure 4.2).
