A floor perimeter safety rail arrangement for the protection of workers on a cement floor. The cement floor has an upper surface thereon upon which they are working. The rail arrangement comprises a cement encasable hollow receiving base having a lower end for welded attachment to an "I" beam support surface and a "floor-even" upper end arranged to be even with the upper surface of the cement floor; a stanchion post removably securable onto the receiving base; and a locking arrangement for temporarily securing and unlocking the stanchion post with respect to the receiving base; wherein the base comprises a means for temporarily securing the stanchion to the upper surface of the floor, wherein the "floor-even" upper end of the base also comprises a means for leaving a flat planar floor where nothing extends beyond the upper surface of the floor upon removal of the stanchion from the base encased within the cement floor.
