What ramp ratio is mandated for all Class B ramps?

For Class B ramps, the mandated ramp ratio is 1:8. This ratio is significant as it ensures that the ramp is accessible and provides adequate slope for individuals using wheelchairs or other mobility devices. The 1:8 ratio means that for every 8 units of horizontal distance, the ramp rises 1 unit in vertical height. This slope is gentle enough to help prevent falls and make it easier for individuals to ascend or descend the ramp safely.

This standard is often outlined in accessibility guidelines such as the Americans with Disabilities Act (ADA) requirements, which set forth specifications to promote inclusivity for individuals with disabilities. Compliance with these ramp ratios is crucial, as it directly impacts the safety and usability of facilities for all individuals.
