Overhead Powerline Tips for Construction Workers
|
Overhead Utilities
On a construction site or at home, overhead power lines can present hazards to anyone doing work over head. Accidental contact with power lines while doing work such as cleaning gutters, painting the outside of your home or operating cranes or booms, can result in serious injury or death.
Stay safe and make sure you observe OSHA guidelines:
- For lines rated 50 kV. or below, minimum clearance between the lines and any part of the crane or load shall be 10 feet;
- For lines rated over 50 kV., minimum clearance between the lines and any part of the crane or load shall be 10 feet plus 0.4 inch for each 1 kV. over 50 kV., or twice the length of the line insulator, but never less than 10 feet;
- In transit with no load and boom lowered, the equipment clearance shall be a minimum of 4 feet for voltages less than 50 kV., and 10 feet for voltages over 50 kV., up to and including 345 kV., and 16 feet for voltages up to and including 750 kV.
- A person shall be designated to observe clearance of the equipment and give timely warning for all operations where it is difficult for the operator to maintain the desired clearance by visual means.
