12.20.060 Opening or stairway requirements.
   All openings through the sidewalk or street into any such vault, space, room or structure shall be kept covered and guarded. If the opening is a manhole or trapdoor, an adequate, strong metal cover must be provided and must be equipped with rough surface so that there will be no danger of any pedestrian slipping on it. If a stairway is provided, the stairway must be properly guarded with a railing at least three feet high to protect pedestrians from injury.
