You must take steps to eliminate or minimise the risks when working near overhead power lines, so far as is reasonably practicable. Orchard and horticulture workplaces should think about what they plant near overhead power lines that may grow into the safe distances around the power lines in the future. Staying outside The Safe Distances

Possible Safety Distances to Consider for EMF Sources. The following table of Safe Distances from EMF Sources is offered below to help reduce your exposure to electromagnetic fields (EMFs). But the actual EMFs emitted from different sources can vary greatly, and the distances needed to reach a desired "safety level" are difficult to predict.

Equipment traveling under or near a power line must: (a) Have a lowered boom/mast and support system (b) Obey minimum clearance distances set in Table T (c) Reduce speeds to minimize breaching (d) Use a dedicated spotter if closer than 20 feet (e) Illuminate or identify the power lines at night (f) Identify and use a safe path of travel. TABLE T

Erect and maintain an elevated warning line, barricade, or line of signs, in view of the operator, equipped with flags or similar high-visibility markings, at 20 feet from the power line (if using Option (2) of this section) or at the minimum approach distance under Table A (see § 1926.1408) (if using Option (3) of this section).If the operator is unable to see the elevated warning line, a ...

An example of one and the same property located near high voltage power lines. It is for sale frequently, gets sold and some time after is back on the market for a long time. High voltage power lines can be problematic at far greater distances, but small street power lines can also produce similar problems.

Overhead power lines are subject to strict guidelines for minimum height clearances over streets, sidewalks, alleys, driveways, and other traffic areas. This is a safety consideration, aimed at keeping people safe from the danger of shock.

advice. If the line cannot be moved or made dead you will need to assess the risks and agree a safe system of work. This may involve the erection of barriers to keep machinery a safe distance away from OHPLs, and other precautions as described in the HSE guidance note Avoidance of danger from overhead electric power lines (see ‘Further ...

Look up for power lines when using tools of any kind. Even nonmetallic tools can conduct electricity. Cranes and derricks that approach working distance within 20 feet of power lines with operating voltages up to 350 kV, or within 50 feet of power lines with voltages greater than 350 kv, are mandated to take “encroachment prevention measures.”
