The owners of real properties, on which transmission facilities are located or over which electrical power lines run, have, in principle, free access to their real properties, which they may use freely while maintaining suitable precautions. They may run their business activities freely using certain equipment and machinery or engage in farming without time limitations. However, it is always important to exercise elementary caution and apply common sense when using transmission facilities.

The equipment included in electrical power lines is designed to minimise the risk of negative effects on persons in the vicinity of the lines. The location of lines is planned so that the transmission facilities do not pose a threat to surrounding human habitats, and so that they blend into the landscape to the greatest extent possible.

In order to eliminate possible hazards, our qualified employees take periodic preventive measures consisting in line surveys and inspection of their condition. If the event of circumstances requiring an intervention, they take actions to eliminate situations that potentially threaten property and people present in the vicinity of the lines. These activities are especially intensified in situations of increased risk or crisis, such as floods or hurricanes. In this aspect, cooperation of the company's employees and the owners of real properties adjacent to electrical power lines, who are often the best source of information regarding the phenomena occurring there, is also important. The goodwill and help of those people can significantly help to address potential risks or shorten the process of remedying a failure.

1. Unauthorized climbing poles and touching of transmission equipment, especially power lines, is forbidden.
2. It is prohibited to erect new residential buildings or new civil structures with rooms to be regularly occupied by people directly under the line or in its buffer zone (the area directly under and on both sides the line).
3. Owners of properties that are farmlands may freely cultivate crops on their land and work using heavy farming equipment (combines, tractors, seeders, and other mechanical farming machinery). Caution is required at the same time – especially in situations where the machinery or equipment used has long booms or is tall by design.
4. There are no restrictions on grazing cattle or other livestock under or right next to overhead lines, nor are there any impediments to the creation of fish ponds. According to review papers and data published by the World Health Organisation (WHO), electromagnetic fields in the vicinity of extra high voltage power lines are not harmful to livestock.
5. Plantings that would come dangerously close to electrical power lines are not permitted due to the potential risk of tree branches touching the electrical power lines. PSE conducts continuous monitoring of company-owned equipment. In case of excessive growth of trees or shrubs near lines, appropriate cutting works are carried out. This work is conducted at the expense of PSE, and the wood obtained during cutting works is transferred to the real property owners. Our company currently performs tree cutting according to a five-year standard, for which the contractor provides a four-year guarantee. The distance of the conductors from the tree crowns is, therefore, determined based on the current crown dimensions, taking into account the five-year growth appropriate to the tree species and the site. In the event of above-normal growth during the guarantee period, additional work is performed immediately at the contractor's expense. Cutting work is only required under strictly defined circumstances. In situations where ornamental or orchard trees that do not reach significant heights are planted, the work mentioned above is not necessary. wymienionych prac jest zbędna.

There is no potential for adverse environmental impacts outside the designated buffer zone area. In addition, stringent requirements imposed for residential development areas are met.
