All materials and equipment required in construction operations shall be stored and placed so as not to endanger the public, the workmen or adjoining property as follows:
(a) Design capacity. Materials or equipment stored within the building, or on sidewalks, sheds or scaffolds shall be placed so as not to overload any part of the construction beyond its design capacity, nor interfere with the safe prosecution of the work.
(b) Pedestrian walkways. No materials or equipment shall be stored on the street without a permit issued by the Superintendent of Inspection. When so stored they shall not unduly interfere with vehicular traffic or the orderly travel of pedestrians on the highways and streets. The piles shall be arranged to maintain a safe walkway not less than four feet wide, unobstructed for its full length, and adequately lighted at night and at all necessary times for the use of the public.
(c) Obstructions. Material and equipment shall not be placed or stored as to obstruct access to fire hydrants, standpipes, fire or police alarm boxes, utility boxes, catch basins, or manholes, nor shall they be located within twenty feet of a street intersection, or so placed as to obstruct normal observations of traffic control lights, or to hinder the use of bus loading platforms.
