Fast, Low-Cost Premium Slip Compliance Evaluations
with Engineering Authority
Slip and fall incidents are one of the main causes cited in personal injury litigation.
Just having the testing done may not be enough to reduce liability if it is proven that:
- Appropriate testing methodology has not been employed;
- Test results have not been appropriately interpreted and classified; and
- Suitable control measures implemented.
A Compliance Report will deliver the assessment outcome
i.e. a determination of compliance that states conclusively whether minimal criteria have been met.
● Know what the results mean
○ Tests include all data, classification and interpretation (Compliance Report)
○ Fitness for purpose
○ Assessment of safety risk
○ Specification for new or existing designs
● Assessments per nationally recognised standards, codes and legislation
● All reports have Engineering Authority to determine compliance
All test data is interpreted for you – because test results are almost meaningless unless you understand and are able to navigate test results in conjunction with relevant compliance criteria, as specified in the Handbooks, building codes and legislation. We also make assessments as to the (minimal number of) areas that should be tested – so that our clients are not left guessing about anything.
● Assessments endorsed by certified Engineers
○ nationally recognised accreditations i.e. Engineers Australia, Materials Australia, etc.
● Years of experience encompassing all possible scopes of testing & materials
● Accident/incident investigations and Expert Witness services to all courts, including Supreme, County and Magistrates; VCAT
● Slip Incident Investigations: Forensic reports & Expert Witness services to all courts
● Evaluations can include lighting, activities, stairs, slopes, contamination, distractions, etc.
● Provision of advice on remediation and recovery procedures
● Cost sensitive ongoing monitoring programs
Applicable Standards (Australia)
● AS 4586:2013 Slip resistance classification of new pedestrian surface materials
● AS 4663:2013 Slip resistance measurement of existing pedestrian surfaces (in situ):
○ assesses slip resistance under a wide range of environmental conditions
● Relevant building codes and legislation e.g. National Construction Code (NCC), OH&S/WHS, DDA, etc.
● Induction Group’s Engineering Authority allows for:
○ expert opinion where the standards or the floor location or condition are not entirely transparent or definitive, and
○ development and implementation of specialised test regimes and procedures for cases where the standards can’t be followed.
Dry Floor Friction Testing
• suitable for testing surfaces under dry environmental conditions
• uses electronically powered equipment aptly called the “Tortus’ to measure the dynamic Coefficient of Friction (CoF) directly
A weighted rubber slider is dragged across the surface at constant speed for 800mm, generating test results. The test run is then repeated in the perpendicular direction and the results are averaged as the ratio of the horizontal and vertical forces (CoF).
While the dry floor friction test is recommended for predominantly dry areas, at least one wet testing method should be used for all external & internal surfaces that have a reasonably foreseeable risk of becoming wet.
Wet Pendulum Testing
• direct measure of the friction between test foot and floor surface
• the spring loaded rubber test slider of the foot exerts a quantified force as it slides across the (wetted) surface of the test specimen
• Rubber sliders are either Four S/slider 96 (simulating a standard shoe sole) or TRL/slider 55.
The TRL option is used for highly slip resistant and profiled surfaces.
• Results are expressed as a Slip Resistance Value (SRV) and classified in accordance with HB (Handbook) 197 and HB 198
HB 197 and HB 198 Specification & Classification Criteria
HB 197 and HB 198 provide guidelines for the specification and classification of slip-resistant pedestrian surfaces.
Guidance is also provided on ‘deemed to satisfy’ provisions introduced into the NCC in 2014 for particular applications such as stair treads, nosings and some ramps, as well as appropriate slip rating, criteria for verifying compliance, and design for slip resistance of sloping surfaces.
