A light-weight, liquid-blocking ring assembly for a surface drain for preventing a harmful liquid spilled nearby from entering the drain, which can be quickly and easily installed by a single person, and includes positive verification that none of the undesired liquid has entered the drain. The assembly includes (1) a center portion having a latching mechanism for attaching and drawing the assembly towards the drain, (2) a peripheral band which surrounds and is spaced from the drain, and which carries at its bottom edge a resilient gasket conformable to the surface surrounding the drain, and (3) an intermediate structure connecting the center portion and the peripheral band without blocking a clear view of the entire surface surrounding the drain.

A device for preventing a liquid flowing over a hard liquid-impervious surface from entering a drain of said surface, which comprises: a support structure, including a central portion, a peripheral band portion having a top edge and a bottom edge, and an intermediate connecting portion for affixing the peripheral band portion to the central portion; a gasket of resilient material which is affixed to the peripheral band portion of the support structure, said gasket being impervious to said liquid and conformable to the surface about the drain over which liquid flows to enter the drain, said gasket being disposed along the bottom edge of the peripheral band portion, wherein the band and gasket assembly has a height greater than the anticipated depth of the flowing liquid and has an inner periphery of a size and shape such that the band and gasket assembly can be disposed on the surface to completely surround and be spaced from the drain; and latching means, disposed on the central portion of the support structure, for attaching and drawing the device towards the drain so as to press the gasket of resilient material carried by the peripheral band against the surface surrounding the drain with sufficient force to prevent the flow of liquid therebetween; wherein the intermediate connecting portion of the support structure comprises a plurality of spaced-apart members, each affixed to and extending between the central portion and the top side of the peripheral band portion, the number and widths of the intermediate connecting portion members being such that most of the inner periphery of the gasket and most of the entire surface within the inner periphery of the gasket and surrounding the drain is visible in a plan view of the device, each intermediate connecting portion member being spaced at a distance from said surface so as to allow the entire surface within the inner periphery of the gasket and surrounding the drain to be readily observed and inspected visually after the device has been installed.
