Slips Assessment Tool |
The Slips Assessment Tool (SAT) is a computer program freely available from the HSE.

The slips assessment tool is a way for those without an in depth technical knowledge of slips to assess slip risk in house relatively inexpensively. The SAT can be used with theoretical data to show the impact changing a certain factor would have on the slip risk of a floor.

Based around the slips potential model, taking into account controllable and predictable factors affecting slip risk, the slips assessment tool aims to provide a way to identify areas of high slip risk.
This tool is intended for the novice and does not give the same degree of accuracy or reliability of assessment as a formal pendulum test. Unfortunately, due to the reliance of the program on Rz data, reports generated can be misleading. It should not, therefore, be considered as a method for specifying floors or fulfilling statutory requirements for slip testing. Results from the slips assessment tool are unlikely to stand up to the scrutiny of legal proceedings. The shortcomings in the accuracy of the slips assessment tool come from its basis on surface roughness measurement. Surface roughness measurements predict hydrodynamic squeeze film behaviour, unreliably, whilst pendulum assessment directly and accurately measures it. Surface roughness can give an indication of slip risk, however it can be highly variable within a relatively small area. |
