Which of the following is not a minimum height for handrails at ramps?

The minimum height for handrails at ramps is governed by safety codes and standards to ensure they provide adequate support and safety for users. When considering the options provided, the correct answer of 38 inches is significant because it exceeds the standard regulations typically set for handrail heights.

Handrails on ramps are generally required to be installed between 34 inches and 38 inches above the ramp surface. This range is designed to offer support to individuals traversing the ramp, particularly those with mobility challenges. Heights below this range, such as 30 inches or 32 inches, do not meet the minimum safety requirements, thus prioritizing safety standards.

By identifying 38 inches as not a minimum height, it highlights that while it is within the acceptable range, it does not function as a minimum measure, illustrating the importance of adhering to the established guidelines that balance usability and safety effectively.
