Final answer:
Frame scaffolds exceeding 125 feet in height are allowed with additional support and are subject to special inspection to maintain safety standards. Options A) Prohibited and D) Permitted without any restrictions are incorrect as safety is a paramount concern.
Step-by-step explanation:
When dealing with frame scaffolds exceeding 125 feet in height, there are specific regulations that must be followed to ensure safety. The correct answer to whether these types of scaffolds are allowed is B) Allowed with additional support. This means that such scaffolds must have extra support mechanisms in place to maintain structural integrity and safety. Support can take various forms, including but not limited to, additional bracing, tying into the building at specific intervals, and ensuring that the scaffold is designed by a qualified engineer. Moreover, option C) Subject to special inspection is also important to note as these scaffolds will require special inspection protocols to ensure they conform to safety standards. These may include adherence to Occupational Safety and Health Administration (OSHA) standards or local regulations depending on where the scaffold is erected. As for options A) and D), frame scaffolds of this height are neither prohibited nor permitted without restrictions as safety is of paramount concern on construction sites.
