What is the maximum slope of an egress exit ramp?

1. 1:12

2. 1:10

3. 1:15

4. 1:8

The correct answer is: 1:12

The maximum slope of an egress exit ramp is 1:12, which means for every 12 units of horizontal distance, the ramp can rise 1 unit vertically. This standard is widely adopted to ensure accessibility and safety for all users, particularly those with mobility impairments. The 1:12 slope ensures that the ramp is not too steep, allowing individuals using wheelchairs or other mobility aids to navigate the ramp without excessive effort or risk of falling. A steeper slope, such as 1:10 or 1:8, would create significant challenges and hazards, making it difficult for individuals with disabilities or those carrying heavy loads to safely use the ramp. Meanwhile, a gentler slope, like 1:15, although more accessible, may not be considered necessary for general building codes regarding egress ramps. Therefore, adhering to the 1:12 standard strikes a balance between safety and functionality.
