Every person who digs or causes to be dug in or adjoining any street, alley or public ground any excavation whatsoever, and every person who occupies or causes to be occupied any portion of any street with building material or any obstruction shall provide sufficient warning lights and barricades to adequately protect pedestrian and vehicular traffic. Such person shall cause not less than two warning lights to be secured and conspicuously posted in or near such excavation, building material or obstruction, one or more at each end of the space excavated or occupied. If the space occupied by such obstruction exceeds ten feet in extent, then such person shall cause additional lights to be posted as aforesaid, for every additional ten feet in extent of the position excavated or occupied, as aforesaid, and shall keep such lights burning during the hours of darkness or at any time when ordinary visibility is obscured. The Safety-Service Director may, in his discretion, require additional lights in the case of any excavated area. In the case of excavations, whether in or adjoining a street, alley or public ground and in the case of other open or exposed places within the City, suitable warning barriers shall be set up to protect against accidents. No opening across a public street or alley shall extend from the curb or edge thereof to a point further than one foot beyond the centerline of the street or alley without being refilled and the surface of the street or alley restored in accordance with the provisions of this chapter and the rules and specifications of the Director.
