Failure Analysis

Our Business, Slip Resistance Testing • Established since 1985.

• NATA accredited for Wet pendulum, Dry floor friction, Oil wet & Wet barefoot incline platform testing.

• Active member of the Australian Standard’s Committee for Slip Resistance Testing.

• Services in this area include; Routine Testing, Risk assessment, Incident investigation and Expert witness.

Why is it important to know the Slip Resistance Value of a finished surface?

Possible Answers?

1. Compliance to AS standards 2. Fit for purpose 3. Duty of Care

Likelihood of Injury?

Changing Age Demographics

Case Study “G.J Coles and Co. Ltd yesterday agreed to pay $2.8 million in an out-of-court settlement to a woman who gave birth prematurely to brain-damaged twins after slipping on the floor of a Coles store�

Johnson, P., 05/08/1992, The AGE, pp. 3

Location: Coles Supermarkets Dandenong, Victoria.

Incident: Slip and fall (spilled drink) Injury: Premature birth of twins who were born with brain damage Testing: Wet Pendulum Test Method (standard was in DRAFT form, pre-AS/NZS standard) Investigation: Dr. Gary Martin, ATTAR provided an Expert Report presentation.

Reporting to the draft Standard for the first time a quantitative interpretation of floor friction was presented.

Slips, Trips & Falls • •

•

Slips occur when a person’s foot unexpectedly loses traction with the floor, resulting in a loss of friction (eg, wet or highly polished floor, spills, unsecured mats).

Trips occur when a person is walking and their foot or leg unexpectedly “catches” on an object, resulting in a loss of balance (eg, uneven surface, trailing cord or open drawer).

Slips or trips can cause injuries without a fall because the force produced by the loss of balance –together with the awkward postures of regaining balance – can sprain ligaments in joints or strain muscles.

Slips: Common hazards

1. Are there sudden changes in floor surfaces?

2. Are the surfaces clean?

3. Are the surfaces suitable?

Duty of Care - slips, trips and falls This means – • any risks to health and safety, including those resulting from slips, trips or falls, must be eliminated, so far as is reasonably practicable • if it’s not reasonably practicable to eliminate the risks, they must be reduced, so far as is reasonably practicable Risk controls need to aim at eliminating or minimising the workplace risks which lead to slips trips and falls, before trying to modify people’s behaviour in the presence of risks.

Source: Work Safe Victoria 2011

Duty of Care - slips, trips and falls • Maintaining Duty of Care by continuous monitoring pedestrian surface through regular testing, the facility ensures the risk of slipping remains known and a responsible risk management plan is maintained. (Food Hall x 20mins : Mats at entrance)

• Regular monitoring involves slip resistance testing with either or both methods in AS/NZ 4663. (cleaning regime) • With time, a pedestrian surface may deteriorate and become more slippery. The Client may elect to replace or treat the surface rather than accept the increased risk of slipping.

Slip Resistance Standards Standards recently published by Standards Australia: • AS 4586 - 2013 Slip resistance classification of new pedestrian surface materials, now supersedes AS/NZS 4586 - 2004. • AS 4663 - 2013 Slip Resistance measurement of existing pedestrian surfaces, now supersedes AS/NZS 4663 - 2004.

Accelerated Wear Testing (AWT)

1. The AWT comprises an initial wet pendulum test on five (5) individual specimens 2. The subsequent AWT is applied to one specimen only, the specimen which shows the LOWEST slip resistance value.

Importance of Surface Preparation • • • • • • •

For any painting project, surface preparation is critical.

Floors (typically concrete) require abrasion Diamond Grind Track Blasting Abrasive Blast Site restrictions Acid etching.

Surface Cleanliness • • • •

Cleaning is required Remove dust & dirt Contamination Concrete will dust

Slip Resistance • • • •

A particle is incorporated to make a rougher surface.

Many different ways of achieving this Different legislative requirements for locations Extra slip resistance reduces cleanability

Types of Aggregates (1)

Types of Aggregates (2)

Ensuring the Standard is Achieved • Laboratory samples get tested • Contractor needs to follow the specification strictly, to replicate on the job.

• The correct amount of aggregate is vital.

• Site testing can be done to verify the standard has been achieved.

Impact of Slip Resistance on a Coating • Adding an aggregate changes the composition of the film • Add inert particles into the film • Can increase the voids in the film • Ponding water can have an impact on the film • The rate of wear of the coating also changes • As a result, the slip rating will change with time • Cleaning the surface becomes more challenging

General Coating Erosion (Car Park)

Linemarking on Concrete • Minimal surface preparation is generally the rule • Car parks are often very smooth and dense concrete finishes • Very fast drying product – No substrate penetration • Subject to vehicle traffic, often in turning zones which has a high compressive force • Limited options to reduce slip due to drying times and application techniques.
