An incredibly common question posed by architects, insurers, lawyers, construction companies, safety & risk professionals and building operators alike is:
“How slip-resistant does my floor need to be?”
Not all floors need to be slip-resistant in wet or contaminated conditions. But in certain areas within buildings – including some that are often misunderstood as not being that foreseeably wet – you do need a certain level of slip safety.
Take external floors. You cannot argue that these floors are known to be wet. As such, they must be safe when wet. This is designated in the UK as having a wet slip potential of a Pendulum Test Value of 36+. Floors must be safe in their intended end use, per the law.
We advocate a pragmatic, zonal approach to slip safety, taking into account analysis of the CHIMES model. In some cases, though, per the above, it would be expected in the event of any HSE action, civil or criminal proceedings, that a certain level of wet slip potential is achieved and maintained irrespective of the other factors in CHIMES.
So we need to ensure that we have floors that are slip-resistant enough for the areas in which they are laid.
Equally, in recent years we have started to see examples of over-specification of slip resistance. Either architects who are ill-informed, or over-zealous suppliers of floor-related products or services tend to be the worst culprits.
Much poor advice exists on this subject so we have pulled together our views on this subject – based on our decades of practical experience, coupled with our work with insurers, lawyers and regulators – into an interactive tool.
