901.08 PROTECTIVE BARRIERS AND ROUTING OF TRAFFIC.
   (a)   It shall be the duty of every person cutting or making an excavation in or upon any public place to place and maintain barriers and warning devices necessary for the safety of the general public.
   (b)   Barriers, warning signs, lights, etc., shall conform to the requirements of the Director. Warning lights shall be flares, torches, lanterns, electric markers or flashers used to indicate a hazard to traffic from one-half hour (1/2 hr.) before sunset of each day to one-half hour (1/2 hr.) after sunrise of the next day. Torches shall be open wick or flame flares or bombs, generally used in connection with roadway repairs or construction, and operating on kerosene or similar fluid.
   (c)   The permittee shall take appropriate measures to assure that during the performance of the excavation work, traffic conditions as near normal as possible are maintained at all times so as to minimize inconvenience to the occupants of the adjoining property and to the general public.
   (d)   When traffic conditions permit, the Director may, by written approval, permit the closing of streets and alleys to all traffic for a period of time prescribed by him, if, in his opinion, it is necessary. The written approval of the Director may require that the permittee give notification to various public agencies and to the general public. In such cases, written approval shall not be valid until such notice is given.
   (e)   Warning signs shall be placed far enough in advance of the construction operation to alert traffic within a public street and cones or other approved devices shall be placed to channel traffic, in accordance with the instructions of the Director.
