Abstract: PURPOSE: A method for decreasing a gale pressure in an energy absorption manner and an explosion proof wall using the method are provided to minimize a mechanical loading to be applied to explosion proof equipment of explosive substance storage facilities. CONSTITUTION: The method for deceasing a gale pressure in an energy absorption manner adopts an explosion proof tissue(20) made of fine porous material. The fine porous explosion proof tissue can reflect a gale pressure produced by an explosion and absorb the gale pressure as deformed energy of the tissue while the gale pressure passes the tissue so as to decrease the gale pressure with viscosity dissipation depending on speed gradient. The explosion proof tissue uses fine metal screen mesh.
