What does 8.2 require?

A manual or power-assisted boarding device must be available at any accessible entrance to a conveyance (other than a dedicated school bus or small aircraft) where the vertical rise or gap exceeds 12 mm or the horizontal gap exceeds 40 mm, measured under clauses 5.1(f) and 7.1(e) of AS 3856.1 (2021). The device must be available for use at all designated stops and deployed whenever a passenger asks. It must be at least 800 mm wide, have a slip-resistant walking surface complying with clause 4.1 of AS 1428.1 (2021), support a total weight of 300 kg and be labelled with its maximum load both on the device and beside the accessible entrance. Boarding ramps (other than on ferries) must comply with clauses 7.1(d) and (e) of AS 3856.1 (2021), portable ramps not fixed to the conveyance must have vertical edge barriers 65 to 75 mm high, and an external boarding ramp must not be steeper than 1:14 for unassisted use (1:8 if the ramp is 1520 mm or shorter) or 1:4 where the driver or another person provided by the operator assists. Hail-and-ride passengers must be able to hail the service at accessible boarding points where the device can be deployed, and those points must offer equal access.
