Abstract
A chemical containment vessel provides an environmental seal around a bottle containing hazardous chemicals for use in manufacturing processes. An enclosure vessel is made of upper and lower assemblies connected together to form a cavity for housing the bottle. A gasket between the upper and lower assemblies provides the environmental seal for the containment vessel. The inner conduits of first and second coaxial conduits are coupled to the inlet and outlet of the bottle for transporting the hazardous chemical to a reaction chamber. The outer conduits of the first and second coaxial conduits are connected to the cavity to nitrogen purge any chemical compound escaping from the bottle into the cavity. The escaping hazardous chemical can be detected and removed in a safe manner.
