The process of self-ignition of a hydrogen-air mixture during the interaction of a shock wave with a destructible granular screen or permeable wall was studied experimentally. The wall was made of polyurethane, the destructible screen was made of quartz sand with a small amount of binder. The parameters of incident, reflected and transmitted shock waves were determined at an initial pressure of 0.02 MPA and a molar hydrogen concentration of 14%. Conditions were determined under which the placement of the destructible screen may be appropriate to prevent spontaneous ignition of the mixture. Keywords: destructible screen, shock wave, hydrogen, ignition.
