We consider the destruction of dust at high galactic altitudes based on an earlier developed model of the movement of dustin the Galaxy, due to the stellar radiation pressure, gravity and gas drag. The possibility of dust sweeping is consideredtaking into account its collisions with the Galactic gas and between dust particles. Also, we clarify the range of grain sizesthat can get into intergalactic space due to the described mechanism.
