Ramp runs shall have a running slope not steeper than _____.

1. 1:22

2. 1:28

3. 1:48

4. 1:12

The correct answer is: 1:12

The correct answer is based on accessibility standards that ensure ramps are usable by individuals with disabilities. A ramp with a running slope not steeper than 1:12 means that for every inch of vertical rise, there should be at least 12 inches of ramp run. This standard is critical as it helps to ensure that the ramp is navigable for wheelchair users and other individuals with mobility impairments. In contrast, other options represent slopes that are steeper than the recommended maximum for accessibility. A slope of 1:12 provides a manageable incline, whereas a 1:22, 1:28, or 1:48 slope would indicate less steepness, thus not aligning with typical ramp standards where a gentle slope is essential for safety and usability. The 1:12 ratio establishes a balance between stability and ease of ascent or descent, making it the universally accepted guideline in building codes regarding ramp construction.
