1. The invention method of improving explosion safety in closed spaces by attenuating the effect of a combustion wave or shock wave on a protected surface, comprising placing obstructions before the protected surface in the form of elastic membranes filled with a flame-retardant substance, characterized in that 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, wherein 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.
