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.
