    I will explain right away that I searched the forum in the topic I am interested in and I did not find a clear answer what regulations or standards prohibit the laying of electrical installation wires - I note that in a non-flammable conduit - in gravitational ventilation ducts. Some write that it is possible, others refer to the "REGULATION OF THE MINISTER OF INFRASTRUCTURE of 12 April 2002 on the technical conditions to be met by buildings and their location." in which there is nothing about running installations in gravitational ventilation ducts. I would like to ask you to indicate specific provisions of standards or laws that prevent such assembly.

    Do you want to consciously reduce the cross-section of an important installation line?

    There are no such unambiguous records. The owner of the facility (or manager or administrator) decides on the installation method after consulting a chimney sweep. If the assembly was carried out in such a way that "there is no path for the spread of fire" and the patency of the ventilation duct is not disturbed, I believe that there are no other obstacles. There was a similar thread recently, maybe you can use something: https://www.elektroda.pl/rtvforum/topic1129384.html#5679078

    You can also use the WC sanitary sewer riser.
    Also Ordinance of the Ministry of Infrastructure of April 12, 2002. does not forbid it.

    This "recently" means that the WT Regulation has been amended fifteen times since then.
    Coming back to the topic, I propose to note that ventilation regulations were written with cemetery crosses and I do not know a chimney sweep who will tolerate any wires in ventilation ducts. All the more I do not understand people who, completely ignorant of the situation on the spot, advise plugging the sewers like professionals. And if there is a gas installation in the building?
    This is what extreme irresponsibility looks like, my dear Colleague.

    I did not refer to this regulation. But since you indicate them, then quote the current interpretation and the fragment regarding this case. Don't take this to be mean, but unconstructive criticism doesn't help at all.

    Mine just tolerates it. In a similar situation, he only ordered:
    - place the wires in a rigid conduit
    - conduit made of non-combustible materials,
    - install in a "way that does not hinder inspection of the duct".

    That's why I wrote: The owner of the facility (or manager or administrator) decides on the method of installing the installation after a possible one consult a chimney sweep ". I think that both the administrator and the chimney sweep will take into account the comments regarding gas (which the author does not mention).

    There are no materials, especially "non-flammable" plastics.

    The ventilation duct is not a cable shaft (duct).
    But I do not understand why you are asking if you can see that you want to push these wires for ventilation, contrary to logic?

    Regulation of the Minister of Infrastructure on the technical conditions to be met by buildings and their location:

    § 268. 1. Installations of mechanical ventilation and air conditioning in buildings, with the exception of single-family buildings and individual recreation, should meet the following requirements:
    3) other installations should not be carried out in the ventilation ducts;

    NOTE: this is MECHANICAL ventilation, not GRAVITY ventilation, with the exception described above.

    That is, water, gas installation. CO, sanitary sewage system, rainwater sewage system, compressed air installation, WLZ - you can?

Report a violation of the law

Topic summary

The discussion revolves around the regulations concerning the installation of electrical wires within gravitational ventilation ducts. Participants express differing opinions on the legality and safety of such installations. Some assert that there are no explicit prohibitions in the "Regulation of the Minister of Infrastructure of 12 April 2002," while others emphasize the importance of consulting a chimney sweep and ensuring that fire spread is not facilitated. A key point raised is that mechanical ventilation regulations explicitly prohibit other installations in ventilation ducts, but this does not apply to gravity ventilation. The consensus suggests that installation methods should prioritize safety and compliance with local regulations, particularly regarding the use of non-combustible materials and maintaining duct accessibility for inspection.
