In industrial buildings with a height of more than 10 m to the top of the cornice, external steel fire escapes should be provided; in buildings with lanterns and elevation differences, in addition, there must be fire escapes connecting the coatings at different levels.
Fire escapes should be designed:
- for buildings up to the top of the cornice (or up to the top of the parapet) 30 m and more - inclined at an angle of no more than 80 °, 700 mm wide and with intermediate platforms - at least every 8 m in height;
- for buildings with a height to the top of the cornice (or to the top of the parapet) less than 30 and - vertical with a width of 600 mm.
The distance between fire escapes along the perimeter of the building should be no more than 200 m.
Crane overpasses are equipped with ladders located at least 200 m apart, and if the length of the crane runway is less than 200 m, the overpass must have at least one ladder located at one of the ends of the span. Ladders to crane ramps, landing and repair platforms are accepted with a width of at least 700 mm, and the distance between steps is no more than 300 mm.
For access to the crane runways, permanent ladders are arranged with an angle of inclination of no more than 60 °. No vertical ladders are allowed.
The distance between the deck of the crane bridge and the lower belt of the supporting structures of the coatings is taken at least 1.8 m, and the distance from the highest points of the crane to the lower belt of the supporting structures of the coatings is not less than 100 mm.
The distance from the landing sites and running galleries to the main trolls located at an accessible distance should be at least 2.5 m. At a shorter distance, the main zip lines at the landing sites and running galleries are fenced off with nets.
Freight lifts are the most common type of vertical transport, their placement in a production building is determined by the course of the production process. Since elevators, like stairs, are connected with passages along the infantry, it is recommended to block them into transport hubs. In the case of built-in arrangement of transport units, their dimensions must be combined with the dimensions of precast floor slabs and roofs.
Doors in the walls of the hoist shafts must open outward and be fireproof.
The shaft, intended to accommodate several lifts, is unclosed to the full height with steel nets separating the lifts from each other. The device under the lift shaft of premises intended for the stay of people is not allowed.
The distance from the top of the hoist at its highest working position to the structures of the charge overlap is arranged at least 600 mm, and the distance from the bottom of the hoist at its lowest position to the mine floor is at least 750 mm.
The width of the passages between the parts of the lifting mechanism and the walls of the engine room must be at least 500 mm, at the exit from the engine room a free area of at least 1 X 1 m is provided.
