Floor materials should be slip-resistant.

They should have a slip-resistance (coefficient of friction) that is not less than 0.4 when measured by the tests specified in the Australian Standard on the slip-resistance of pedestrian surfaces (AS/NZS 3661.1 - 1993). The tests should be performed with the Tortus floor friction tester for dry surfaces and Stanley Skid Tester for wet surfaces.

Concrete floors should be wood-float finished or rendered slip-resistant by some other suitable means (such as a broom finish or a coating containing abrasive grit). If a concrete floor contains an aggregate then it should be angular not rounded.

Surfaces in offices should preferably be carpeted (timber floors tend to be marginally slip-resistant at best); uncarpeted surfaces should comply with AS 3661.1.
