BEFORE TRYING TO GET ON OR APPROACH THE VEHICLE:
• Is it necessary to approach the vehicle? Can the operator handle the problem from the platform?
• The best procedure is to disconnect or shut off the power to the lines.
• Do not let anyone approach the vehicle until you evaluate where the power line contacts the Aerial
Device.
• Is it above the insulated section of the upper boom?
• Is it above the lower boom insulated section?
• Is it below any insulated sections and a direct short to the vehicle?
• If the vehicle is grounded properly:
• Use a hot stick or hot line tool to perform the operation.
• Approach the vehicle using the shuffling step.
• Lay a rubber blanket down by the vehicle and step on it before attempting to jump on the vehicle.
• Do not touch the ground and the vehicle at the same time. Even a properly grounded vehicle may
have a lethal voltage difference between the truck and ground.
• If the vehicle is not grounded:
• Do not approach the vehicle unless you use insulated blankets to step on as you approach the
vehicle. Stepping from one rubber blanket to the next.
• Use a hot stick or hot line tool to perform the rescue operation while standing on the rubber
blanket.
• As a last resort, jump onto the vehicle.
• Do not touch the ground and the vehicle at the same time.
TOP CONTROL SHUT-OFF
When a situation requires the upper controls be overridden (such as, injured personnel in the platform), use
the Top Control shut-off at the lower controls to stop oil flow to the boom tip. This will make the upper
controls inoperable. Then “lower” controls can be used to lower the operator to the ground, provided the
upper controls are intact. The Top Control shut-off functions as an emergency stop by taking oil flow away
from the active controls.
If the operator is unable to operate the Aerial Device, determine if any damage has occurred to make the
Aerial Device inoperable. If the situation allows safe operation from the lower controls, override the upper
controls and carefully lower the platform to the ground. If the Aerial Device will not operate due to the
damage incurred, consider one of the other auxiliary operating procedures presented in this section to solve
the problem.
