Alabama Contractors License Practice Exam

Access to underfloor spaces shall be at least how many square feet?

1. 3 sq ft

2. 5 sq ft

3. 4 sq ft

4. 6 sq ft

The correct answer is: 3 sq ft

Access to underfloor spaces must be a minimum of 3 square feet to ensure that adequate space is available for inspection and maintenance activities. This requirement is crucial for ensuring that contractors and maintenance personnel can safely enter these often cramped and potentially hazardous spaces to perform necessary work, such as inspecting plumbing, electrical systems, or foundations. The 3-square-foot minimum allows for a standard-sized access opening that provides enough room for an individual to navigate into the underfloor area, ensuring visibility and operational access without compromising safety. This standard helps enforce building codes designed to promote safety and accessibility in various construction contexts. The other options provide insufficient access space, which would not meet these critical safety and operational requirements.
