What is the new class ratio for a ramp as per fire codes?

The correct answer regarding the new class ratio for a ramp as per fire codes is indeed 1:12. This ratio is important because it dictates the maximum slope allowed for ramps to ensure safety and accessibility, particularly for individuals with disabilities.

A ratio of 1:12 means that for every inch of vertical rise, there must be at least 12 inches of ramp run. This design provides a gradual slope that is manageable for users, allowing them to ascend or descend comfortably without risking falls or injuries. The 1:12 ratio aligns with accessibility standards set forth in various codes, including the Americans with Disabilities Act (ADA), which stresses the necessity of safe and navigable pathways for all individuals.

In comparing this to other ratios, options such as 1:8 or 1:10 would result in a steeper slope, which may be too challenging for some users, particularly those using wheelchairs or other mobility devices. A steeper ramp can also increase the risk of falls and decrease the overall usability of the ramp for everyone. Therefore, the adoption of the 1:12 ratio helps to foster an inclusive environment while adhering to safety regulations.
