High-Voltage Power Lines
-Great care must be taken when working or operating equipment near overhead high-voltage power lines
-The required minimum safe distances (clearance) from overhead lines energized by 600 V to 50,000 V are:
a. For boom-type equipment in transit, 6 feet.
b. For boom-type equipment in operation, 10 feet.
c. For people working near overhead lines, 6 feet.
Note: see 2946 for minimum required clearances from voltages greater than 50,000 V.
-Amusement rides or attractions shall not be located under or within 15 feet (4.57 m) horizontally of conductors operating in excess of 600 volts
-The following activities are prohibited unless overhead power lines have been de-energized and visibly grounded:
a. Work over high-voltage lines.
b. Work within required clearances.
Note: when work is to be performed within minimum required clearances, the operator of the high-voltage line must be notified by person or persons responsible for the work before proceeding with any work which would impair the aforesaid clearance.
