Safety of power lines

In the immediate vicinity of power lines, there are dangers that need to be taken into account during excavation as well as construction, forestry and agricultural work in order to avoid accidents.

Overhead lines

Working under powerlines with large machinery requires caution

Power lines are high, but not high enough to safely work under with large machinery such as

  • dump trucks,
  • log trucks,
  • lifts or combine harvesters.

Dangerous situations are most often caused by vehicles as well as forestry and construction equipment, especially their moving parts, such as the jib of a crane or the bed of a dump truck. Therefore, the following should always be kept in mind:

  • pay attention to the height of the vehicle and its movement radius. the safe distance from a line is considered at least 2,5 m, both on public roads and, for example, on a field or in a forest.
  • driving with machinery that has a height of more than 4,5 m and with vehicles that have a height of more than 3,5 m on roads and elsewhere (for example fields, forests) requires a permit.

When a machine comes under voltage

When a machine comes under voltage, it must not be exited, as it would increase the danger. Wait for outside help and confirmation that the line has been switched off before exiting the vehicle.

Construction and forestry work can be carried out only with the permission of the owner of the power grid

Planned forest cutting, construction and earth-moving work or material storage in the protection zone must be approved with the owner of the power grid. Outside the protection zone, trees must not be felled in the direction of a nearby power line. Logs must not be stored under an overhead line or in its immediate vicinity. If a tree has fallen on a line, call 112 or the line owner. The line must be switched off by the line owner to safely remove the tree.

A campfire can cause a life-threatening electric shock

A campfire must not be made close to an overhead line, even if there is no wind and the campfire can be kept under control. An electric shock may occur between the flame rising from the campfire and the powerline even when the flame is several metres away from the powerline. Such an electric shock would endanger the lives of people within a 25 metre radius. In addition, the heat rising from the campfire causes the line cords to stretch, as a result of which the powerline will lower closer to the ground and the risk of an electric shock will increase further.

Cords that are on the ground must not be approached

If you notice a line that has fallen to the ground, you should not go closer than 20 metres, as the it can be a live-wire and thus life-threatening. Report it by calling 112 and block access to the line. If you are in a danger zone, you can get out of it safely by keeping your legs together the whole time, by dragging them on the ground or by small jumps.

Working close to power lines

Before starting excavation, it must be clarified whether there might be cables or paths in the excavation area.

Do the following:

Cable lines have an underground installation and crossing them without the approval of their owner is prohibited. Without approval, it is prohibited to:

  • cross a cable or piping system, for example with a tractor or a log truck
  • carry out excavations, build construction works, cut down forest and transport logs
  • make a campfire in the protection zone
  • grow trees and bushes in the protection zone

Approving work

All work in the protection zone of overhead lines and cable lines must be approved by their owner!

Elektrilevi’s approvals

If it is necessary to cut down trees in the protection zone of a power grid or outside the protection zone, and if the possibility of trees falling into the protection zone has not been excluded, please contact us in the following ways for permission.
