302 Floor or Ground Surfaces

10. Floor or Ground Surfaces
302.1 General
Floor or Ground Surfaces
Floor or ground surfaces shall be stable, firm, and slip resistant and shall comply with 302.
The following excerpts from Advisory address the minimum requirements for stable, firm, and slip resistant surfaces.

11. What is a stable surface?
One that remains unchanged by contaminants or applied force, so that when the contaminant or force is removed, the surface returns to its original condition.
Grass and sod surfaces are not prohibited, however, they typically will not meet this criteria.

12. do not meet this criteria.
What is a firm surface?
One that resists deformation by either indentations or particles moving on its surface.
Soft or loose materials such as sand, gravel, bark, mulch, or wood chips surfaces
do not meet this criteria.

13. What is slip resistance?
One that provides sufficient frictional counterforce to the forces exerted in walking to permit safe ambulation.
Slip resistance is the most controversial and difficult to measure since there are many types of surfaces and testing methods and compliance is applicable when wet or dry.
In 2009, the National Floor Safety Institute issued the ANSI/NFSI B101.1 which is a new national safety standard for testing dry, hard surfaces.

14. It was recommended to DOJ that they apply an American Society for Testing & Materials (ASTM) standard (with modifications) to the 2010 SAD to assess whether or not a floor surface is "slip resistant”…
DOJ declined the recommendation since there is no generally accepted test method for the slip-resistance of all walking surfaces under all conditions.

15. However, DOJ did include ASTM standards in the 2010 SAD applicable to safe surfaces under and around playground equipment.
ASTM standards are referenced in:
(Referenced Standards)
(Play Areas: Ground Surfaces)

16. “ADA /TAS – Seal of Approval”?
What surfaces have the
“ADA /TAS – Seal of Approval”?
ADA-Approved
None…neither DOJ nor TDLR endorses or approves any products or manufacturers.
ADA-Certified
TAS-Compliant
Compliance is typically dependent on the
installation and maintenance.
