Abstract: FIELD: methods of explosion protection. 
     SUBSTANCE: invention relates to protective devices used in explosive and radioactive facilities, such as easy detachable panels and roofs, blast guards and shields, pressure relief valves. Method of industrial buildings explosion protection is in that performing installation of the explosion-proof elements in the building enclosing structures, in which the explosive and fire hazardous equipment is operating. In the building enclosures, making the explosion-proof elements, wherein for the side enclosures, the explosion-proof elements are arranged in the form of building enclosure safety collapsing structures containing reinforced concrete panels, each of which consists of collapsible and non-collapsible parts. Non-collapsible part is made in the form of load-bearing ribs placed along the contour of the collapsible part, and the collapsible part is made in the form of at least two coaxially located depressions in the wall of the building, one of which, the external one, is formed by planes of right quadrangular truncated pyramid with a rectangular base, and the other, the internal one, represents two inclined surfaces connected by an edge, with formation of a groove, and to the placed along the contour of an organized collapsible structure load-bearing ribs at least three horizontal rods are attached, on which an armored screen is placed, which is fixed to the rods by locking elements. For the upper enclosures, explosion proof elements are arranged in the form of explosion-proof plates on the building roof or attic. Explosion-proof plate is made containing a metal armored frame with metal armored plating and a lead filler, which has four fixed support pipes at the ends. In the building roofing, four support rods are rigidly embedded, which are telescopically inserted into the fixed support pipes of the plate, to the ends of the support rods, on the metal frame facing side, additional elements are attached, damping effect of the blast wave, made combined, for example, elastic-damping, in the form of an elastic element, for example, a filled with polyurethane spring. On the support rods between the additional elements and a metal frame with armored metal lining bushings from the quick-collapsible material are placed. Elastic-damping element can also be made with a quick-collapsible disposable element in the form of a bushing from brittle, collapsible material, which is secured to the stopping sheets by means of a damping base attached to the stopping sheets with screws, and to the base, coaxially to the rod, securing the disposable bushing, wherein the elastic-damping element flexible part is made in the form of at least three leaf springs arranged between the stopping sheets and the bushing-type clamping element with grooves for fixing of the springs one end, at that, each spring second end is secured onto stopping sheets by hinges. Springs are arranged with a slope of about 15°÷45° in the direction of a quick-collapsible disposable element in the form of a bushing, and between the armored screen and the locking elements, coaxial to the rods, bushings from a quick-collapsible material are arranged, which are fixed on the rods. On its side surface, fixing the security indicator in the form of a resistance strain gage, the signal from which is sent to the strain amplifier via the communication line, and from the strain amplifier to the unit of emergency mode of operation warning system. 
     EFFECT: increased reliability of operation of personnel in highly explosive premises.
