With constant changes to the NCC and the BCA, it is no small task for builders, renovators and property owners to ensure that they are compliant.
In regards to floor safety requirements, there have been a few recent changes that impact on pedestrian safety.
In regards to stair nosings, the NCC has changed the code to specify that the stair nosings return (down the front of the stair tread) is not to exceed 10mm, whereas in the past the code specified a 25mm drop. Any new buildings or major renovations require that stair tread nosings comply.
The slip resistance required has not changed however, the type of rating has changed from a ramp slip rating to a pendulum slip rating. The slip rating required will depend whether the stair are internal or external.
Although not a change to the NCC, in addition to slip resistance, there must be a minimum of 30% luminance contrast between the stair treads and the stair nosings.
Another important change to consider is the BCA's requirement that residential stairs be slip resistant. In the past, this requirement was only applicable to commercial buildings. However, the recent changes prescribe a P4 or R10 slip resistance for internal timber stairs in private residences. Without this, an owner will be unable to obtain their occupancy certificate.
This slip resistance can sometimes be difficult to achieve on sealed timber, marble and high gloss tiles. However, Grip Guard has a floor safety solution for almost any pedestrian flooring. For help choosing the correct floor safety solution, phone us to discuss your requirements.
