Whenever any person or corporation shall, under authority of this chapter or otherwise, place any obstruction in a street or alley or make any excavation therein for any purpose whatsoever, it shall be the duty of such person or corporation to keep the obstructions or excavation properly safeguarded by substantial barricades and display lighted red lanterns or other lights or flares from dusk until daylight in conformity with such regulations as may be specified by the City Engineer. Whenever, in the opinion of the City Engineer, the public safety is so seriously endangered by such cuts or excavations as to require constant supervision from dusk to daylight to insure that all barricades are in proper condition and location, all warning lights are burning, and all traffic is properly routed around such barricades, the person to whom the permit for work has been granted shall be responsible for furnishing a night watchperson for that purpose.
