Abstract
An apparatus for containing and scrubbing toxic or corrosive gases from a leaking pipe or cylinder is provided. A gas passageway attaches at one end to a leakage location on a pipe or cylinder, and at the other end to an air operated exhauster. The air operated exhauster, through the input of a non-flammable purge gas, creates an exhaust flow from the leakage location to a drum which is attached to the air operated exhauster. The drum contains a scrubbing media which, when it contacts the leaked gas, cleans or removes the harmful component, thus allowing release to the atmosphere of the cleaned air.
