The question of evacuation of the interstellar medium of the host galaxy of a quasar is examined. Compton heating due to hard X-rays from the quasar is considered. It is shown that the evacuation radius is much smaller than that hitherto believed and that it is redshift dependent. It is also shown that evacuation of the central part of the interstellar medium need not switch off the central engine, the quasar. 34 references.
