Discover why the wet Coefficient of Friction between the floor and a shoe heel is NOT a constant value, unlike the Dry Coefficient

Find out why it is necessary for the Test Machine to reproduce certain essential characteristics which occur when a pedestrian’s shoe slides across the floor

Find out which Test Machines and Methods do actually reproduce those characteristics

SlipAlert LLP was founded by Dr Malcolm Bailey. Although SlipAlert sells all over the world via our partner programme and to many global corporations, SlipAlert remains a family business owned and operated by Malcolm Bailey and his marketing director Andrew Stewart.

Malcolm Bailey – Managing Director

Dr Bailey, who designed SlipAlert, was the first person to understand why TRL Pendulum results correlated so well with the known accident history of the floors tested. He realised that the uplift experienced by the Pendulum slider on a wet floor was almost identical in its effect to that experienced by a pedestrian’s heel when he or she slipped. It was therefore only by combining the various design parameters in a particular way that a test machine could accurately simulate a pedestrian’s heel in slipping.

Dr Bailey is Chairman of TC 339, the European Standard Committee for harmonisation of slip testing, and is Chairman of the BSI Committee which was responsible for BS7976, the Pendulum Standard. During the past 25 years he has tested many hundreds of floor surfaces and investigated hundreds of slipping accidents. Dr Bailey is the former Secretary of the UKSRG ( UK Slip Resistance Group) a position he held for many years.

Malcolm is the senior consultant with Radlett Consultants, recognised as one of the leading forensic engineering companies in the UK.
