This value varies according to the measurement The standards require ground and floor surfaces to be slip resistant,īut they do not specify a minimum level of slip resistance orĬoefficient of friction.

What is the minimum level of slip resistance required by the standards? Not perform adequately unless it is sufficiently stabilized by binders,Ĭompaction, or other treatments and will likely require repeated Wheeled mobility aids due to the vibrations they cause.ġ/2″ Maximum Change in Level Common QuestionsĬoncrete, asphalt, and other paved surfaces are more reliably compliant,īut other materials, such as wood, and construction methods can be used Materials can be difficult and sometimes painful to negotiate with Rough surfaces composed of cobblestones, Belgian blocks, and similar Surfaces, but they do not further address overall surface smoothness. The standards limit changes in level and openings in floor and ground Used to increase a surface material’s slip resistance may requireĬontinued maintenance or re-application. With the standards as slip resistance is important not just forĪccessibility but for general safety as well. Minimizing floor or ground slipperiness will likely satisfy compliance Textures, or finishes that prevent or minimize slipperiness under theĬonditions likely to be found on the surface. Resistance rating based on a laboratory test procedure.Ĭompliance with the standards requires specifying surface materials, Some flooring products are labeled with a slip Resistance can only be meaningfully specified according to a particular Systems are unique to the test method, specific levels of slip Or the field, a widely accepted method has not emerged. Protocols have been developed over the years for use in the laboratory (coefficient of friction) because a consensus method for rating slip However, the standards do not specify a minimum level of slip resistance Or semi-ambulatory or who use canes, crutches, and other walking aids. Hazards to people with disabilities, especially those who are ambulatory Slip ResistanceĪccessible surfaces must be slip resistant to minimize Binders, consolidants, compaction, and grid forms may enable some of these materials to perform satisfactorily but require repeated maintenance. Most loose materials, including gravel will not meet these requirements unless properly treated to provide sufficient surface integrity and resilience.
