A system for the containment of a toxic material storage vessel is disclosed. In one example, a cylindrically shaped hollow jacket having upper and lower half sections are fastened together along flanged borders to form a leak resistant seal for enclosing a conventional toxic material storage vessel therein. Elongated channels extend the length of the jacket along upper and lower surfaces of the upper and lower half-sections, respectively. The channels communicate with the interior of the jacket and are tilted relative to the horizontal such that lighter-than-air gases escaping from the vessel migrate along the upper channel and accumulate at one end of the jacket and such that a liquid leaking from the vessel gravitates along the lower channel and accumulates at the same end of the jacket where conventional gas and liquid detecting means is employed to detect the presence of such accumulated liquid and gases. A second example comprises a cylindrically shaped jacket mounted on one end and containing a raised disc shaped base eccentrically located relative to a longitudinal axis of the jacket upon which a conventional toxic material storage vessel rests, whereby a crescent shaped depression is formed in a lower end portion of the jacket for accumulating liquid leakage from the vessel. |
