Building Code Administrators and Inspectors Florida Principle and Practice Licensure Practice Exam

The running slope of walking surfaces shall be no steeper than _____.

1. 1:22

2. 1:28

3. 1:48

4. 1:20

The correct answer is: 1:20

The correct choice reflects the requirement that the maximum running slope of walking surfaces, such as sidewalks or ramps, must not be steeper than a specified ratio to ensure safety and accessibility. A ratio of 1:20 indicates that for every 20 units of horizontal distance, there can be a rise of 1 unit. This guideline is crucial because steeper slopes can pose risks for individuals with mobility challenges, including those using wheelchairs or other assistive devices. In the context of building code regulations, particularly those related to accessibility, maintaining a moderate slope is essential for compliance with standards like the Americans with Disabilities Act (ADA). These standards are established to create an inclusive environment, promoting ease of access for all individuals. A less steep slope, such as the other options provided, would not be incorrect for some situations, but in this particular context, the requirement for a maximum slope of 1:20 aligns with the broader goals of ensuring that walking surfaces are not only usable but also safe for the general public.
