Electrical Hazard Warning
THE SNORKELIFT AERIAL WORK PLATFORM
IS NOT ELECTRICALLY INSULATED.
Electrical Hazard
DANGER
If the platform, booms, or any other conductive part of a Snorkelift contacts a high-voltage electrical con
ductor, the result can be SERIOUS INJURY or DEATH for persons on or near the machine.
GO NO CLOSER THAN THE MINIMUM SAFE APPROACH DISTANCES
(M.S.A.D) - AS OUTLINED IN TABLE 1. AND FIGURE 3.,
ON THE NEXT PAGE.
Be sure to allow for sag and sway in the wires and the work platform.
If a Snorkelift comes in contact with a live electrical conductor, the entire machine can be charged.
If that happens, you should remain on the machine and not contact any other structure or object within
reach. That includes the ground, adjacent buildings, poles, and any object not a part of the Snorkelift.
Suchcontact could makeyourbody aconductor to theother objectcreating an electricalshock hazardre-
sulting in SERIOUS INJURY or DEATH.
DO NOT attempt to enter or leave the Snorkelift until you are sure the electricity has been turned off.
If aSnor kelift is in contactwith a liveconductor, the platform operator MUST warn others on the ground in
the vicinity of the Snorkelift to STAY AWAY from the machine, since their bodies can also form a path for
electricity to ground thus creating an electrical shock hazard with possible ELECTROCUTION and
DEATH.

Regard all conductors as energized.
Personnel working on or near a Snorkelift must be continuously aware of electrical hazards, recognizing
that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.
