The “maximum experimental safe gap” (MESG) is the maximum distance (between two flat plates) which still allows flame propagation through the gap; it is for hydrogen 0.08 mm. The “quenching gap” in air is the distance (between two flat plates) at which ignition of a flammable mixture is suppressed.
