Abstract
Method and apparatus for increasing the velocity of sweeping gas as it moves across a gas delivery system contained in a hazardous material delivery enclosure, e.g. a gas cabinet valve manifold box or gas isolation box. An exhaust port with selectively opened and closed apertures juxtaposed to non-soldered or non-welded fittings or connections in the gas delivery system is placed in or on said enclosure to create an accelerated and directed flow of sweeping gas across the non-soldered or non-welded fittings or connections.
