Certified Playground Safety Inspector (CPSI) Practice Exam

Ramps with no handrails or a single rail and no barrier do not necessarily require a curb projecting above the ramp because they do not have a guardrail that could potentially block the wheelchair from slipping off the ramp. Additionally, ramps less than 48 inches high may not need a curb unless there is a risk of falling. Therefore, ramps must have guardrails that extend to within 1 inch of the ramp surface to ensure safety for wheelchair users and avoid the need for a curb.
