An apparatus for safely delivering a hazardous fluid substance to a receiving structure includes a supply cylinder containing the fluid substance and having a supply cylinder release port; a high pressure containment vessel having a vessel wall, for receiving and safely enclosing the supply cylinder; a high pressure first tube extending from, and in fluid communication with, the supply cylinder release port to a vessel port in the vessel wall; and a vessel valve in fluid communication with the first tube for controlling delivery of the fluid substance from the supply cylinder and from the vessel. The vessel valve preferably includes a fluid substance sensing valve assembly mounted in the vessel port, for automatically shutting off the flow of the fluid substance at the vessel port upon detection of the fluid substances outside the containment vessel. The vessel valve preferably includes a reduced orifice controller. A process of delivering a hazardous fluid substance from a supply cylinder having a supply cylinder release valve using the above-described apparatus, including the steps of placing the supply cylinder into the containment vessel; connecting the supply cylinder release valve to the tube extending within the containment vessel; opening the cylinder release valve and the vessel valve to deliver the fluid substance from the supply cylinder and from the containment vessel.
