Handling and delivery system for dangerous gases

摘要

Method and apparatus to contain dangerous gases venting or leaking from a primary containment vessel. An outer containment vessel holds the primary containment vessel in fluid tight relationship to the outer vessel. The outer vessel has an internal volume large enough to contain the entire contents of the inner vessel and includes means to absorb or scrub gas leaking from the inner vessel. Removal of gas from the inner vessel to a point of use is controlled by valves and conduits contained in the outer vessel, the valves being controlled from outside the vessels.
