What is the maximum slope allowed when beveling changes in level between 1/4 inch and 1/2 inch?

1. 1:2

2. 1:4

3. 2:3

4. 1:3

The correct answer is: 1:2

When beveling changes in level between 1/4 inch and 1/2 inch, the maximum slope allowed is 1:2. This means that for every 1 unit of vertical rise, there should be 2 units of horizontal run. This slope is significant in maintaining accessibility and safety standards, particularly for individuals with disabilities. The guidelines typically follow the Americans with Disabilities Act (ADA) and other building codes, which strive to minimize the steepness of changes in elevation to reduce the risk of trips and falls. A 1:2 slope provides a gentle transition that is easier for individuals using wheelchairs, walkers, or other mobility aids to navigate. This is crucial in residential, commercial, and public buildings to ensure compliance with accessibility requirements and to provide a safe environment for all users. Utilizing a steeper slope, such as those described in the other options, would not meet the standards required for changes in level, which could compromise safety and accessibility. Therefore, 1:2 is the appropriate and acceptable maximum slope in this context.
