Abstract
The invention relates to methods of decreasing the effect of blast loads on industrial spaces relating to, inter alia, nuclear power plant and large chemical manufacturing facilities. A method of improving explosion safety in closed spaces by attenuating the effect of a combustion wave or shock wave on a protected surface consists in placing obstructions before the protected surface in the form of elastic membranes filled with a flame-retardant substance. A non-flammable gas is used as the substance filling the membranes; the membranes themselves are made of a material that disintegrates during, and under the action of, displacement of the front of a combustion wave or shock wave along the surface of the membranes. The membranes are filled with a non-flammable gas immediately after flammable gas is detected at a dangerous concentration in the space in front of the protected object. The technical result consists in increasing explosion safety, decreasing the effect that an explosive wave formed in an accidental explosion of fuel-air mixtures has on the walls and floors of protected spaces.
