Thus, there is no reliable safety distance for neighborhood power lines. In general, a magnetic field level of 0.5 mG will be reached somewhere between 10 and 200 feet from the wires. But you cannot tell by simply looking up at the power lines. You have to test on-site with a gaussmeter to be sure.
At FPL, safety is a cornerstone of our commitment to our customers, our employees, and those working in the community. We urge anyone who is working near power lines to work safely to avoid serious injuries, save lives, and prevent property damage. Coming into contact with a power line can be dangerous – even deadly.
Determine if any part of the equipment, load line or load (including rigging and lifting accessories), while operating up to the equipment's maximum working radius in the work zone, could get closer than the minimum approach distance of the power line permitted under Table A (see § 1926.1408). If ...
Don’t climb trees near power lines. Never fly kits, remote control airplanes or balloons near power lines. If you get something stuck in a power line, call Dakota Electric to get it. Keep a safe distance from overhead power lines when working with ladders or installing objects such as antennas.
Electricity can "arc" or jump from power lines across a gap, to tools or ladders that you're using. Always maintain a safe distance from power lines: stay back at least three metres (10 feet) from any power lines near your home. That's about the length of a standard four-door car.
Is There a Safe Living Distance from Power Lines? Hundreds of studies worldwide have shown that living next to high voltage power lines and other parts of the power transmission network increases your risk of cancer and other health problems. The closer you are the more you are bombarded with dangerous EMFs.
*According to 1926.1409, for power lines over 350 to 1,000 kV, the minimum distance is presumed to be 50 feet. Over 1,000 kV, the utility/owner or a registered engineer must establish it. Cranes cannot be assembled/disassembled below an energized power line or within the Table A clearances from a power line.
The power line owner/operator or registered professional engineer who is a qualified person with respect to electrical power transmission and distribution determines the minimum clearance distance that must be maintained to prevent electrical contact in light of the on-site conditions.
The minimum safe distance from high-tension electrical wires varies if your concern is for your general health. For people working near electrical wires, at least one utility company advises keeping all equipment under 14 feet tall when near power lines.
Since power lines may carry huge amounts of current, often at high voltages, substantial electromagnetic fields (EMF) are created. In the case of high-voltage transmission lines, the EMF can extend to about 300 meters. Power Line EMF is strongest directly underneath the power lines, and gradually fades away with increasing distance.
