Pedestrian Slip and Fall News

The ANSI standard for specification of ceramic tile (ANSI A137.1), which is referenced by the International Building Code, was revised in 2012 to introduce a new method for specifying the slip resistance of tile. Rather than relying upon the dated ASTM C1028 standard in which the static coefficient of friction of tile surface is measured, slip resistance is assessed based upon the dynamic coefficient of friction, as measured using a Binary Output Tribometer (BOT). To perform such testing, Romualdi Davidson has purchased a Reagan Scientific BOT 3000E. This instrument allows measurement of the dynamic coefficient of friction per the standard, as well as the static coefficient of friction. This is a new step forward in the objective measurement of slip resistance, since this device performs a prescribed, computer-controlled measurement, effectively eliminating variances due to human error or misuse. In addition, for the first time, the standard offers an interpretation of dynamic coefficient of friction values that is based upon empirical testing of human test subjects that has been conducted to quantify the dynamic friction actually required to support normal human gait.
