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 defined by ANSI standards.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, stack, 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 in-
cludes 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.

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, stack, 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, recogniz-
ing that death or serious injury can result from contact with an energized conductor.
