Abstract
A perimeter warning system is provided having a plurality of substantive stand bases and stanchions, which when combined together with a flag line provide a means to demark the perimeter of a surface across which there is danger. The stand bases include a surface onto which an insertion sleeve is placed, for holding the stanchion stably, and an opening symmetrically equidistant from the center of the surface of the stand base from the sleeve. In this way, stand bases can be stacked together with the sleeve of one placed in the opening in the surface of the other for stability. The system includes storage and transportation elements; wherein the surface of the base stand defines an opening through which the pillar of a storage unit can be threaded to stack the plurality of base stands together onto the storage element. Stanchions are provided with storage boxes configured to stack together neatly and stably.
