HEALTH + SAFETY
performed before, during and after the tile is worn down by
running an abrasive pad over the surface. Plotting the result of
the pendulum tests against the number of cycles the pad had
been run over the surface can then be used to show how the
slip resistance of the tile is affected by its use and cleaning.
Each batch of surfaces is different, and therefore each
accelerated wear result will be different, but there is a common
trend: an initial quick drop in slip resistance, which then plateaus
out. This shows that with most surfaces, the main loss of slip
resistance occurs quickly and at the start of the surface's life.
The accelerated wear test is a good tool to use when selecting
surfaces, as planning on having adequate slip resistance down
the track can save time and money in anti-slip treatments and
replacing of the surface.
A time frame cannot be associated with the accelerated
wear test, because the amount of wear is dependent on the
frequency of use and the type of traffic over the floor. For
example, a tile laid on a residential balcony will wear slower than
if that same tile was laid in a busy shopping centre, due to the
frequency of use.
Floor treatments are a common, often cheaper, way to increase
the slip resistance of a surface without having to replace the entire
surface. A few of the more common ones are sealers (with or
without grit), acid etching, grinding/sanding and adhesive strips.
The best way to decide on which treatment to use is to
look at the composition and use of the area in question, as not
all treatments may be suitable for different areas. For example,
using an acid to etch restroom surfaces should increase the slip
resistance while keeping it cleanable; however, if a sealer with
grit was used, the slip resistance is likely to be increased, but it
may become difficult to clean.

About Safe Environments
Slips, trips and falls account for a large percentage of injuries
in workplaces and public environments; however, the risk
of incidents can be minimised with the correct measures
in place. Our team performs slip-resistance and accelerated
wear testing to assess the suitability of floor material prior to
installation, and regular on-site slip testing for public liability
risk assessments. We also provide expert witness evidence in
slip and fall accidents. Our independent slip-testing services
are backed by university-qualified consultants in Sydney
and Melbourne, including materials and forensic scientists,
building consultants and architects, and occupational
health and safety specialists, who can assist with further
specialist areas in managing your property risk.
Safe Environments is a Registered Testing Authority as
per the National Construction Codes (NCC), and is NATA-
accredited to ISO/IEC 17025:2005 General requirements
for the competence of testing and calibration laboratories.
This accreditation includes dry and wet slip-resistance
testing to AS/NZS 4663 Slip-resistance measurement of
existing pedestrian surfaces, AS/NZS 4586 Slip-resistance
classification of new pedestrian surface materials, and
BS 7976 Part 3 Pendulum Testers Method of calibration.
Whether we're providing slip-resistance testing or advice
and support for your organisation, you can be confident in
our recognised experience and expertise.
