All walking and working surfaces should be safe, even, slip resistant, and free of debris and holes. Walking and working surfaces may include, but are not limited to, stairs, parking lots, passenger loading zones, and sidewalks. Use the following standards to ensure walking and working surfaces are safe:

  • Identify and clean up spills quickly.

  • Replace or restretch loose or buckled carpeting.

  • Bevel uneven surfaces with height differences between ¼ inch (0.35 cm) and ½ inch (1.27 cm) with a slope of 1:2 or less.

  • Ramp or replace uneven walking surfaces that have a height difference larger than ½ inch (1.27 cm). The slope of a ramp should not exceed 1:12.

  • Patch or fill cracks or holes greater than a ½ inch (1.27 cm) in walkways and parking areas.

  • Paint elevation transitions on curbs, ramps, or walkways that are difficult to see.
