CHAPTER 6: RAMP DESIGN
1.0 Ramps At Work
For your safety, ramps at work must meet all legal requirements for your area. We
recommend:
1.1 Width
. At least four feet wide.
1.2 Guardrails.
To reduce the risk of a fall, sides of ramp must have raised borders
or guardrails at least three inches high.
1.3 Slope Grade.
Not more than a 10% slope grade. A 10% slope grade means
one foot in elevation for every ten feet of slope length. (See Figure 1. below.)
1.4 Surface.
Flat and even, with a thin carpet or other non-skid material. Make
sure there are no lips, bumps or depressions.
1.5 Bracing.
Ramp must be STURDY. You may need bracing so ramp does not
“bow” when you ride on it.
1.6 Avoid A Drop Off.
You may need a section at the top or bottom to smooth out
the transition.
