Stochastic heating of dust particles resulting from dust charge fluctuations is considered in some laboratory situations, where high kinetic temperatures of dust particles have been suggested or could be observed. A particular case, in the conditions of the scrape-off layer in tokamak plasmas, is also considered and it is shown that kinetic energies corresponding to velocities of ≃ km/s can be reached in times of order ≃ 1 ms by micron-size particles interacting with a background of stochastically heated nanosize particles.
