Full Answer

Handrails are required when ramp runs are greater than 6 inches. Handrails must be continuous along the side of the ramp. Handrails can be between 34 and 38 inches high above a ramp's surface and must be at a consistent height. The floor of the ramp or landing needs to extend at least 12 inches beyond the end of the handrail. When handrails are not required, provide a curb or barrier that can block a 4-inch diameter sphere on the edges of the ramp.

The surface of the ramp must be stable, firm, and slip-resistant. There can be no changes in level on ramp runs other than the running slope and cross slope. Ramps that change direction need landings between the runs that are at least 60 inches by 60 inches.

While the maximum running slope for a ramp is 1:12, exceptions can be made when they are required due to space limitations. Provide ramps with the least possible running slope. Work area equipment can decrease the width of the ramp below 36 inches if it is essential to the work being performed.
