FIELD: fire safety.
SUBSTANCE: method of explosion protection of industrial buildings is that in the enclosing structures of a building, in which explosive and fire hazardous equipment is functioning, explosion protection elements, explosive and fire hazardous equipments are installed on the foundation of the building, and explosion protection elements are made in the side and top fences of the production building. For side fences, explosion protection elements are installed in the form of safety fences collapsing of buildings, and for the upper protections - as explosion-proof plates on the roof or attic ceiling building located therein explosive objects, explosion-proof elements operate as explosion-proof plates, comprising metal armored frame with metal armored plating and filling - lead, which is at the ends of the four fixed-bearing pipe, and roof of the building rigidly hurt s four support rods which are telescopically inserted in the fixed panel-supporting tubes. Filler is made in the form of dispersed air-lead system. The lead is made in the form of crumbs, and the support rods are made of elastic, explosion-proof elements are made in the form of a protective collapsible construction of a fence containing reinforced concrete panels, each of which consists of destructible and non-destructive parts. The non-destructive part is made in the form of carrying ribs placed along the contour of the collapsing part, and the fracturing part is made in the form of at least two coaxially located depressions in the wall of the building, one of which, external, is formed by the planes of a regular quadrilateral truncated pyramid with a rectangular base, and the other - internal, represents two inclined surfaces connected by an edge, with formation of a groove. The wall thickness from the edge to the outer surface of the building fence must be no less than δ = 20 mm. When exposed to an explosive shock load, this section of the wall can be split into separate parts. Between the additional elements and the metal frame with armored metal lining, bushings of quick-disintegrating material, for example, glass of the "triplex" type, are mounted on the support rods, and in the upper part of the support rods a damping plate is fixed to the stop sheets, opposite to the panel and in the direction of the shock wave, a buffer device is made in the form of a cone, the top of which is placed on the axis of the opening of the protected object.
EFFECT: increasing the reliability of personnel in explosive areas.
