North Carolina Building Contractor License Practice Exam

For floor decking to be used as a working platform it must hold _____ pounds per square foot.

1. 50

2. 60

3. Cellular

4. 70

The correct answer is: Cellular

For floor decking to be considered a safe and effective working platform, it must have the structural integrity to support a specific load. In the context of construction and building practices, particularly in North Carolina, the standard requirement is that the floor decking should be able to hold a minimum of 60 pounds per square foot. This ensures that the surface can support not only the weight of workers and their equipment but also provides a margin of safety for unforeseen circumstances. Choosing "cellular" does not pertain to the weight requirement but rather describes a type of construction material that might be used. This type of material does not specify the load-bearing capacity required for a working platform, which is critical in maintaining safety and compliance with building codes. Therefore, a numeric answer that reflects the proper load capacity is essential for this question, with 60 pounds per square foot being the correct choice for a working platform made from floor decking.
