VOSI SLIP AND FALL STANDARD V41.23E
SLIP & TRIP RESISTANT SIDEWALKS AND SWIMMING POOL DECKS
1.1 This Standard specifies the static coefficient of friction (SCOF) and trip resistance requirements for sidewalks and swimming pool decks in order to be called "slip and trip resistant".

3.1 All uniform definitions of terms that affect public safety are stated in 2.1
3.2 "Slip Resistant Sidewalks" - A Sidewalk that meets reference 2.1 minimum SCOF requirements when tested dry with leather (0.45) and dry and wet with Monarch EVA (0.50 & 0.35 respectively).
3.3 "Slip Resistant Pool Decks" - A pool or spa deck which meets 3.2 requirements and a 0.35 minimum SCOF when tested wet (per 2.1) with 1/16" thick gray silicone rubber sensor.1
3.4 "Trip Resistant Sidewalks & Pool Decks" -
Reference 2.3 par. 4.5 "Ground and Floor Surfaces" and
References 2.7 & 2.8. Maximum
vertical mismatch of adjacent sidewalk panels, or utility access
covers within walkways, is 1/4 inch maximum without edge treatment. Changes
in level between 1/4 and 1/2 inch shall be beveled with a slope no
greater than 1:2. Changes in level greater than 1/2 inch shall be
beveled with a slope no greater than 1/8 inch.
3.5 "Standing Water" - Water, other than that caused by
rainfall, shall not remain on sidewalks for more than 48 hours.
4. SIGNIFICANCE & USE
4.1 This standard is based on using references 2.1 and 2.2 for measuring the SCOF of sidewalks, pool and spa decks, and footwear. The results of this method correlate with slip/fall accident rate.
4.2 Par. 3.4 requirements will reduce the incidence of trip and fall injuries caused by mismatched adjacent sidewalk panel
heights, or utility access covers within walkways.
4.3 The public's safety requires that uniform specification / test methods be used when measuring the SCOF of walkway and footwear surfaces in both the field and laboratory.
4.4 Sidewalks & pool drawings shall reference this standard.
4.5 Broom finished concrete sidewalks and pool decks will be considered slip
resistant per reference 2.6.(click here for Ref
4.6 This standard should be required in all sidewalk ordinances in order to
define a safe walking surface.
