Roughness vs SlipAlert...


Summer Cashback offer

Roughness can no more predict slip risk of floors than kenny the "fake slip test". Did you know that Rz micro roughness cannot detect contamination, poor cleaning, wear or change to slip risk. This autumn we'll give you up to £900 for your old roughness meter.


Roughness cannot detect contamination

Micro surface roughness measures will remain unaffected by contamination making it useless as a way of measuring the effectiveness of cleaning regimes or as a tool to explain why one area of a floor appears to be a slip hazard. Rz is not a measure of slip risk and cannot be an effective means of monitoring change to the slip risk of floors.

Roughness won't help monitor floor slip risk

On many floors: swiiming pools, profiled floors, contaminated floors, wet floors, or rough floors you may not even be able to measure Rz microroughness. When you can measure, it may vary wildly and it unliekly to tell you much about slip risk of the floor. Rz micro roughness cannot detect contamination the biggest cause of slips nor can it tell you how the slip risk will change as your floor wears.

Roughness and Pendulum

Measures of roughness have poor correlation with the Pendulum. To read more about why it roughness is of little value in floor safety testing click here.


RZ and RA Roughness

Rz and RA are 2 forms of roughness meeasurement. neither correlates well with the Pendulum and neither will tell you anything about contamination. contact SlipAlert


Roughness and poor cleaning...

Contamination makes no difference to the roughness measure of a surface, and so measuring roughness offers no value in testing your clesning regime.


Slip Accident Blackspot and roughness

From time to time an area of your floor may become a slip accident blackspot. When you first observe a slip or a small number of slips i the same area of floor, you may wish to test the area of floor to discover if that area of floor has become dangerous. It may have been caused by a spill that has not been cleaned properly and has made that area of floor slippery. In these situations roughness measures will not help you. You need SlipAlert.


Roughness, spills and contamination

Spills and contamination are one of the biggest causes of floors becoming slippery.


Roughness and SAT

The HSE suggest using roughness measures with SAT, the Slips Asessment tool. Howver the logic for SAt was based on the PTV values of 20 = poor slip resitance and 40 = very good slip resistance. click here to find out more about using SAT with SlipAlert.


SlipAlert / Pendulum and SAT

The SAT programme uses these points of referenece and a notional correlation of 2:1 between Rz and PTV. It would make more sense to use pendulum-correlated vales (from a Pendulum or SlipAlert) and then half the value and enter into SAT.

Rough Luck...

A floor being rough does not mean that it is not slippery. Nor is it always true that a floor that is smooth must necessarily be slippery. Some of our clients have discovered this to their cost. Don't trust your luck by measuring roughness when you can get a much more reliable and accurate reading from your SlipAlert.

SlipAlert better than roughness... (HSE)

“SlipAlert is able to distinguish between a given floor surface in clean condition and in a contaminated condition. This is a key advantage of SlipAlert compared with using surface micro roughness and makes it ideal for monitoring the effectiveness of cleaning” UK HSE

SlipAlert is far better than roughness
