Abstract: A reflective collar attachment which is designed to be attached around the periphery of an existing fire hydrant includes mating semi-circular halves, each of which has formed therewith a pair of integral semi-circular extensions with a number of circular stair-stepped indentations of incrementally decreasing radii. Each half of the collar can be adjusted in inner radius by severing the semi-circular extensions at any of the indentations so that the collar can be adjusted to fit any fire hydrant design. Other embodiments include a collar attachment of three piece construction and a resilient strip with projecting top and bottom teeth which can fit any fire hydrant design or shape. A removable reflective tape web is positioned in a display area positioned around the periphery of any of the collar attachments.

Abstract: A liquid waste disposal and canister flushing system includes a cabinet with a sink for receiving the canister and a subsink for receiving a lower portion thereof. The subsink is connected to a drain line. A plunger subassembly includes a stopper which functions as a drain valve for the canister. An injection jet is connected to water and cleaning solution sources and discharges diluted cleaning solution into the canister for flushing same. The injection jet engages the plunger subassembly for ejecting the stopper from a canister drain opening. A control system includes a programmable microprocessor which can be programmed to provide drain and flush cycles of predetermined duration. A method of liquid waste disposal and canister flushing utilizes the microprocessor for delaying the flush cycle until completion of the drain cycle.
