Electrical Hazard
DANGER
The aerial platform is not electrically insulated. Death or serious injury can result from contact with, or inadequate clearance from, an energized conductor.
-
Do not go closer than the minimum safe approach distance as defined by 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 work platform, 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 con ductor the platform operator must warn ground person nel 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 work platform or any part of the aerial platform is in con tact 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 continu ously aware of electrical hazards, recognizing that death or serious injury can result from contact with an energized conductor.
