1339.17 DEMOLITION.
(a) General. In the demolition of buildings, other than buildings of wood frame construction, one story at a time shall be completely removed. No wall, chimney or other construction shall be allowed to fall in mass on an upper story. Bulky material such as beams and columns, shall be lowered and not allowed to fall.
(b) Chutes.
(1) Chutes for the removal of materials and debris shall be provided in all such parts of demolition operations that are more than twenty feet above the point where material is being removed.
(2) Such chutes shall be completely enclosed. They shall not extend in an unbroken line for more than twenty-five feet, but shall be equipped at intervals of twenty-five feet or less with substantial stops to prevent descending material from attaining dangerous speeds.
(3) The bottom of each chute shall be equipped with a gate or stop, with suitable means for closing or regulating the flow of material.
(c) Sprinkling. Chutes, floors, stairways and other places affected shall be sprinkled sufficiently to keep down the dust.
(d) Utilities and Basement Drainage. Sewers shall be plugged and capped, water service shall be shut off at the main, and gas lines shall be shut off at the main. The basement floor shall be broken to permit drainage.
(e) Grading of Lot. When a building has been demolished and no building operation has been projected or approved, the vacant lot shall be filled, graded and maintained in conformity to the established street grades at curb level, or natural grade. The lot shall be maintained free from the accumulation of rubbish and all other unsafe or hazardous conditions which endanger the life or health of the public; and provision shall be made to prevent the accumulation of water or damage to any foundations on the premises or the adjoining property.
(f) Note. All of the requirements hereinbefore stated in this section covering construction and remodeling shall also apply to demolition.
