(a) Construction. All scaffolding shall be so constructed as to insure the safety of persons working on, or passing under or passing by the scaffolding.
(b) Material. When the extent or location of scaffolding is such as to create an unusual fire hazard, the building commissioner may require the use of noncombustible material or of treated fire-resistive lumber.
(c) Safeguards. All scaffolding shall be constructed, maintained and disassembled in a manner that follows accepted engineering practice and manufacturer's specifications. “American National Standard ANSI A10.8-2001 Safety Requirements For Scaffolding”, as amended, and “American Society of Mechanical Engineers, ASME A120.1-2014 Safety Requirements for Powered Platforms and Traveling Ladders and Gantries for Building Maintenance”, shall be considered as accepted engineering practice, as shall other national standards deemed applicable by the building commissioner.
(d) When scaffolding is, or is expected to be, unoccupied for more than two hours, such scaffolding shall be safely and securely attached to the building in accordance with federal regulations, ANSI standards and the manufacturer's specifications.
(e) When wind conditions actually do, or are predicted or expected to, or based on other measurements can reasonably be extrapolated to, exceed a velocity at the scaffold level identified in the manufacturer's specifications as posing a hazard, such scaffolding shall be lowered to the ground and secured or, if required by the manufacturers' specifications, raised to the roof and secured.
