Toilets belong to several levels of lightning protection

The toilet belongs to the third level of lightning protection, and does not belong to the lightning protection standard building. The specific provisions for lightning protection buildings are as follows:

1. Buildings with first-class lightning protection:

Buildings with a height of more than 100 meters.

2. Buildings with secondary lightning protection:

Residential buildings with 19 floors and above and other civil buildings with a height of more than 50m.

3. Three-level lightning protection buildings.

1) When the number of lightning strikes is greater than or equal to the number of lightning strikes in the current year, or the buildings that need lightning protection are confirmed through survey.

2) The tallest building in the complex or located at the edge of the complex with a height of more than 20m.

3) Historically, more important buildings in areas with serious mine accidents or areas with more lightning accidents.

Obviously, none of these three toilets are compliant.

Toilets in general areas belong to the third level of lightning protection; Toilets with electrical equipment in explosive areas belong to the second level of lightning protection.

Lightning Protection Rating for Buildings:

12 2 1 Class 1 lightning protection buildings.

12 2 1 1 Buildings of particular importance. Such as state-level halls, office buildings, archives, and large-scale exhibition buildings; extra-large and large-scale railway passenger stations; international airports and communication hubs; State guesthouse, large-scale tourist buildings, international port passenger terminals, etc.

12 2 1 2 Buildings and structures protected under national key cultural relics.

12 2 1 3 Buildings with a height of more than 100m.

12 2 2 Class 2 lightning protection buildings.

12 2 2 1 Significant or densely populated large buildings. Such as ministerial and provincial office buildings; Provincial halls, exhibitions, sports, transportation, communications, broadcasting and other buildings; as well as large shops, theaters, etc.

12 2 2 2 Buildings and structures protected by provincial key cultural relics.

12 2 2 319 floors and above residential buildings and other civil buildings with a height of more than 50m and 100m.

12 2 2 4 Large-scale computing centers at the provincial level and above and buildings with important electronic equipment.

12 2 3 Buildings with three levels of lightning protection.

12 2 3 1 When the number of lightning strikes is greater than or equal to 0 05 in the current year (see Appendix D 2), or the building is confirmed to be in need of lightning protection through survey.

12 2 3 2 The tallest building in the complex or located at the edge of the complex with a height of more than 20m 50m.

12 2 3 3 Isolated buildings or structures such as chimneys and water towers with a height of 15 m or more can be 20 m or more in areas with weak lightning activity (the average annual thunderstorm day does not exceed 15).

12 2 3 4 More important buildings in areas with severe or frequent lightning accidents in history.

12 2 4 When determining the lightning protection rating of buildings, in addition to the above provisions, the lightning protection level of buildings can be appropriately improved in areas with frequent lightning activities or strong lightning areas.

Toilets in explosive areas with electrical equipment, Level II;

Toilets in any other area are level 3...
