This patent describes an apparatus for collecting gas from the soil proximate a subterranean enclosure and harmlessly dispensing it in the atmosphere. It comprises: collecting means disposed substantially outside the subterranean enclosure comprising a collection chamber having perforations in the walls of the chamber so the inside of the chamber is in communication with zones outside the subterranean enclosure, suction means comprising a fan having an intake end and an exhaust end and a resealable container within which the fan is disposed wherein the sealed container is mounted outside the subterranean enclosure and under ground level, a ventilation duct having one end connected to the exhaust of the suction means and a second end having access to the atmosphere, Communication means connecting the inside of the collection chamber to the intake end of the fan thereby generating a suction in the collection chamber so that gas in the soil proximate the enclosure and collection chamber is drawn into the collection chamber, with the suction means pulling it therethrough and dispensing it harmlessly into the atmosphere remote from the enclosure.
