Electrical Hazard
The aerial platform is not electrically insulated.Death or serious injury can result from contact with,or inadequate clearance from, an energizedconductor.
Do not go closer than the minimum safe approachdistance as defined by the minimum Safe ApproachDistance 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 platformcontacts a high-voltage electrical conductor, the entiremachine can become electrically charged.
If that happens, remain on the machine and do not con-tact any other structure or object. This includes theground, adjacent buildings, poles, and any other objectsthat are not part of the aerial platform.
Such contact could make your body a conductor to theother object, creating an electrical shock hazard result-ing 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 conductelectricity creating an electrical shock hazard resultingin death or serious injury.
Do not approach or leave the aerial platform until theelectricity has been turned off.
Do not attempt to operate the lower controls when thework platform or any part of the aerial platform is in con-tact with a high-voltage electrical conductor or if there isan immediate danger of such contact.
Personnel on or near an aerial platform must be continu-ously aware of electrical hazards, recognizing thatdeath or serious injury can result from contact with anenergized conductor.
