FIELD: blasting operations.
SUBSTANCE: invention relates to protective devices used in explosion hazardous and radioactive objects, such as easy detachable panels and roofs, blast guard and gates, excess pressure valves. Explosion protection method of explosion hazardous objects with emergency warning system involves the following: weak link elements of the ES safety system, for example, anti-explosion panels, support rods of which have bushings from destructible material, such as triplex type glass, have emergency warning system arranged on them. Between the metal frame with metal armored lining and the upper part of the coating of the explosion hazard object, near the opening intended to release excess pressure, safety indicator is installed; it performs the functions of a weak link in the safety system of explosion hazard object and responds to occurrence of an emergency situation; safety indicator is executed in the form of a sensor responding to deformation, for example, a resistive strain gauge, its output is connected to a signal amplifier, for example strain-gage amplifier, and the output of the strain-gage amplifier is connected to the input of the device of the emergency situation warning system. Explosion protection device is also described.
EFFECT: technical result - increase of reliability of explosion-proof devices in case of an explosion at the site and providing the return of these structures into their initial positions after the explosion.
