The combination of a sloped surface with conditions that can make that walking surface slippery, especially at outdoor building access ramps, forms a falling hazard at both ramp ascent, and ramp descent for nearly everyone. Slope represents the proportion of vertical rise to horizontal length The orientation also can mislead people with vision impairments who use curb slopes as a cue to crossings. Recommendation: Providing the least possible slope below the 1:12 (8.33%) maximum offers better usability for a wider range of users. Comparatively, on a forklift ramp, it takes additional time for a forklift operator to stop their lift. In addition, DOT requires detectable warnings on Thelengths of ramps must always be straight, as curved rampsmake it difficult forthe movement of a person in a wheelchair; in reference to this, the transverse slope of a ramp should also not exceed 2%,thereby avoiding any lateral slippage. industry standards for walking and working surfaces (29 CFR 1910, Subpart D) do not include provisions concerning maximum allowable slopes. For medium distancesbetween 3 and 6 metersthe slope should be less than 8%, and for. Under the ADA Standards, which apply primarily to facilities located on , no ramp shall be inclined more than a slope of one vertical to three horizontal (20 degrees above the horizontal). The specific maximum slope depends on the type of forklift being used. certification in an hour or less. *If you are an individual not currently employed by a company use your personal name in the 'Company Name' field. When additional overhead height is required at a tier, a speed ramp can be incorporated into the design for vehicle circulation.
