Step-by-step explanation:
The question pertains to construction safety regulations in New York City regarding the minimum top height of an unenclosed perimeter protection wire rope cable. After researching the current safety regulations, the correct answer to the question is that the minimum top height of an unenclosed perimeter protection wire rope cable, according to the New York City Department of Buildings (NYC DOB), is 42 inches. This requirement is outlined in the NYC Construction Codes, specifically in the Building Code, which dictates various measures for safeguarding persons and property during construction and demolition operations.
It's important to note that OSHA may have different or additional requirements for safety measures depending on the context, but in the case of New York City, local requirements must also be adhered to. Since the NYC DOB's regulations are designed to address the specific safety needs and challenges within the city, they take precedence for construction projects within its jurisdiction. It should be emphasized that safety regulations are subject to change, so it's crucial for construction professionals to remain updated with the latest requirements from both local and federal agencies.
