What is the maximum slope permitted for clear floor or ground space?

1. 1:48

2. 1:38

3. 1:4

4. 1:2

The correct answer is: 1:48

The maximum slope permitted for clear floor or ground space is 1:48. This standard is important because it ensures accessibility, particularly for individuals with mobility impairments. A slope of 1:48 translates to a rise of one unit for every 48 units of horizontal distance, which is gentle enough to allow wheelchair users and others with mobility challenges to navigate the space safely and comfortably. Maintaining this slope is critical in the design of public buildings and spaces, ensuring compliance with the Americans with Disabilities Act (ADA) and the Florida Building Code. The gentle gradient helps prevent physical strain on users and minimizes the risk of accidents. Other slopes, such as 1:4 or 1:2, are too steep for general use as clear floor or ground spaces, making them unsuitable for accessibility. While 1:38 is more permissible than 1:4 or 1:2, it still exceeds the maximum allowable slope for clear spaces, which should adhere strictly to the 1:48 standard for safety and accessibility compliance.
