Final answer:
The minimum clearance distances for working near power lines can typically be found in safety regulations and guidelines set by national electrical safety authorities such as OSHA in the United States.
Step-by-step explanation:
The minimum clearance distances for working near power lines can typically be found in safety regulations and guidelines set by national electrical safety authorities. In the United States, for example, the Occupational Safety and Health Administration (OSHA) provides standards and requirements for working near power lines.
These regulations are put in place to ensure the safety of workers and prevent electrical accidents. They specify the minimum distances that workers should maintain from power lines based on the voltage and conditions of the power lines. The exact clearance distances may vary depending on the specific jurisdiction and country.
For example, OSHA's regulations state that for voltages up to 50 kV, the minimum clearance distance is 10 feet (3 meters) for qualified workers. This distance increases with higher voltages. It is important to refer to the specific regulations and guidelines in your country or region to determine the minimum clearance distances for working near power lines.
