ELECTROCUTION HAZARD
Vehicle is not insulated.
Do NOT raise boom into power lines.
Look up and use light to search for power lines in the dark.
Keep boom and vehicle a minimum of 20 ft. (6.1 m) away from power lines.
Do not step off a charged vehicle.
If you touch a charged vehicle while standing on the ground, you will die.
Overhead power lines are not insulated. While some lines have a weather covering and appear
to be insulated, they are not. The vehicle or parts of the vehicle do not need to touch the power
line for the vehicle to become energized. Electricity will arc across gaps, and all overhead wires
or cables should be considered hazardous and dangerous. Always operate the crane so that no
part of the crane or load enters the "Danger Zone", the minimum clearance distance for a
powerline.
DANGER
VOLTAGE HAZARD
The danger zone of a particular powerline is based on its voltage. High voltage levels increase
the danger zone. See figure.
