A child drowning protection guard for an open head, plastic industrial container to prevent a toddling child from toppling head first into the container containing a liquid. The guard is provided by a tapered tube integral with the bottom wall of the container and extending upwardly from the bottom wall, through the surface of the liquid, a distance at least one-half the height of the container, and having an effective diameter at the top so that the radial space between the tube and the inner side wall of the container is dimensioned to be less than the diameter of the head of a typical toddling child. The tube is hollow so that a plurality of empty containers can be stacked in nested relationship, and the side wall of the tube can be corrugated or fluted to conserve on the amount of volume taken from the container by the placement of the tube therein.
