Floor ‘Slip-Alert’ Roller Coaster Floor Tester

The (Brand Name) SlipAlert is termed a ‘roller coaster’ floor tester because its’ action is similar to a ride at the fair; or possibly if testing a wet floor, it could be likened to a ‘log flume’ ride, where the vehicle provides a squeeze film as it hits the floor surface.

A digital readout gives the floor test reading which will vary dependent upon floor type and floor condition (example resin floor or concrete floor and wet floor, dry floor or contaminated / slippery floor surface). The reading is converted to a coefficient of friction using a graph.

The Method of use of the Slip-Alert Floor Tester Floor Slip Roller Coaster Slip Alert Equipment

A trolley is rolled under gravity down a long 2 metre sloping ramp. When the Slip-Alert makes contact with the slippery floor surface the floor test equipment rolls on its two front wheels and a single rubber slider at the rear, represents the heel imitating floor slip.

The Advantages of the Slip-Alert Floor Test Equipment

The HSE has suggested Slip-Alert is a good indication* of grip potential. It offers the ability, in wet conditions, to indicate* floor friction of contaminated floor surfaces and...

...though readings tend to be fail-safe (overly safe) than the Pendulum Tester*.

Slip-Alert can also be used to monitor floor cleaning regimes; poor cleaning of flooring is a major contributor in floor slip accidents. Observation of how far the trolley travels after hitting the flooring surface, particularly where a test is conducted on dry floors and then wet flooring also gives a quick visual guide of floor slipperiness.  

The Disadvantages of the Slip-Alert Floor Tester Floor Slip Alert Testing Equipment - Non HSE Approved

Its 2 metre long ramp limits its portability and restricts where it can be used (for example on stairs, narrows corridors, bathrooms or toilets) and additional distance is needed for the Slip-Alert vehicle to travel after it has left the ramp.

It is our experience uneven floor surfaces give inconsistent results and the trolley’s tendency to veer off to the side when it hits the floor increases the time required for the tests.

The trolley can bounce on some floor surfaces (for example - vinyl safety floors) plus dirt on the wheels / floor slide rubber can cause issues. Floor testing of small spills of water or flooring contaminants is difficult as the whole flooring area needs to be affected for accurate contaminated floor or water-wet floor readings to be obtained.

Comparison of Slip-Alert versus Surface Roughness Testers

In comparison with a Portable Floor Surface Roughness Tester (For example the Surtronic Duo or Surtronic 25) the HSE report the Slip-Alert gives floor friction test readings more closely aligned with Pendulum Testing, though not on all floor types*.

For those considering purchasing their own floor testing and floor monitoring solutions, the Floor Slip-Alert purchase price can be higher than some Floor Surface Roughness Testers. The HSE recommends Calibration is conducted where as some Surface Roughness Testers are self calibrating.

In either case, these floor testing equipments should only be used to complement the pendulum slip resistance test, not instead of when considering your duty of care and undertaking a floor safety risk assessment*.

* The HSE has recommended Slip-Alert  or Surface Roughness Testers should not be used to provide accurate evidence for forensic investigation in a court of law or in product specification; only the Pendulum Test is suitable for this purpose to show true floor grip potential and to offset accident injury claims.

Action of  the Slip-Alert vehicle hitting a wet floor is likened to the ‘Log Flume’ fairground ride, where the vehicle, in this case a boat, is propelled, under gravity, down a slope to land on water.

The distance the boat travels or ‘hydroplanes’ when it hits the level surface is dependent  upon the weight of the boat, the speed of its travel, the area and slipperiness of the boats bottom surface, the viscosity (or slipperiness) of the water and how much the water can be ‘squeezed’.

This is similar to imitating a pedestrian heel slip as a floor slip is dependent upon the weight of the person, the speed the heel moves, the area of heel (example - stiletto or safety shoe), material type and the substance it comes into contact with (water, oil, talcum powder, sawdust etc).

There is however a small difference when using a boat as the boat floats and everyone has fun once it settles its rapid movement, whereas a person tends to end up

In casualty, as a floor slip injury claim or worse in the graveyard!
