1. INTRODUCTION

Surefoot Systems UK Ltd was instructed by Mr Ian Douglas of Bowmer & Kirkland to carry out slip assessment testing of 4 resin flooring samples.

2. PENDULUM TEST METHOD – BS7976-2:2013

In order to assess the slip resistance of the floors in question tests were undertaken using a portable Wessex TRL Pendulum slip tester. The tests were carried out in accordance with UK Slip Resistance Group (UKSRG) Guidelines issue (4.0 2011) and BS 7976 – 2 2013 as recommended by the UK Health & Safety Executive. Measurements of the floors surface Pendulum Test Value (PTV) which is closely related to the coefficient of dynamic friction were measured using a fully calibrated Wessex Pendulum machine. Testing was carried out in both dry and wet conditions using the slider 55 developed to replicate a bare foot

Pendulum testing is a method that models the formation of a hydrodynamic squeeze film between the floor and shoe sole, a major factor in wet slip accidents. The test operates by the pendulum arm being raised to the horizontal position and clamped. The arm is then released by the operator and the arm then swings freely driving a pointer around the graduated scale and the retardation of the pendulum arm as it moves across the surface is recorded. The recorded value is representative of the resistance due to friction of the floor covering against the moving pendulum. This simulates the walking action of a person over the surface.

3. United Kingdom Slip Resistance Guidelines

The UKSRG classification of slip potential is based on research undertaken by the UK Building Research Establishment (BRE) The level of friction required by a person to walk without slipping is related to the speed of movement and the step length. The level of friction required also varies from person to person, where persons required level of coefficient of friction is greater than that available from the interaction of the shoe soul, flooring material and any contamination the person will experience a slip accident. The classifications arriving from the BRE study apply to basic conditions e.g. for low activity normal walking environments. Activities such as rushing pulling pushing or turning in any environment are likely to require a higher level of friction than normal walking. Some individuals will experience minor slips from which they can recover their balance without a fall occurring so every slip does not result in a fall accident.

4. Control Measure to Prevent Slips

Where reasonably practical control measures outlined in the HSE guidelines (http://www.hsegov.uk/slips/employersriskas.htm) should be used to control the risk of slips. Attention should therefore be paid to the minimisation of floor contamination before any action is taken to modify or replace the floor surface material or substrate. However the level of contamination required to increase the risk of slips is considered to be minimal. Therefore floors know to be slippery when contaminated must be kept thoroughly clean and dry to maintain satisfactory slip resistance. Where this is not possible consideration should be given to floor surface modification or replacement, SLIP RESISTANCE ASSESSMENT Bowmer & Kirkland – Center Parcs 18.04.14

7. COMMENTS

The results of the slip assessment tests showed that the surface of all 4 resin samples has a dry slip resistance value well above minimum standards and with a slip risk potential of very Low Risk.

The wet slip tests showed that 3 of the resin samples have a very similar wet slip resistance value with all 3 samples providing a slip risk potential of Low Risk in wet conditions. The surface of sample S however showed a wet slip resistance value of 17 PTV when tested which is substantially lower than the other 3 samples and represents a slip risk potential of High Risk.

It should be noted that when a resin is applied to a surface to improve slip resistance there is likely to be variations in the surface finish due to potential inconsistency in application teqniques. This subsequently may lead to variations in the slip resistance and PTV value of the surface particularly over a larger area. Variations in resin manufacture can also result in an inconsistent surface and variable PTV rating.

Although the testing of the samples in question will provide a good indication of the expected slip resistance values consideration should be given to further in situ testing over a larger area to ensure that there are no large variations in surface slip resistance caused by inconsistent application methods.

8. Guidelines

The Assessment of Floor Slip Resistance

The United Kingdom Slip Resistance Group Guidelines

Issue 4.0, September 2011

The criteria for judging the results of slip resistance tests are based on the work of the Building Research Station (now known as the BRE) in the 1960s supported by the experience of investigators and bodies such as the former Greater London Council over the last 40 years. This work suggested that for unencumbered, able bodied, working aged people, a PTV of 36 or above represented an acceptably low risk of slipping when walking in a straight line on a level surface.
