D1P2 generally sets the performance required for safe movement within a building for most people, including those with a disability.

Safe gradient—D1P2(a)

The D1P2(a) requirement for a safe gradient is to facilitate access and safety for all people, and refers to the crossfall as well as the longitudinal grade.

Doors—D1P2(b)

D1P2(b) aims to make sure people are not put at risk by doors impeding egress or causing them to be trapped.

Slip-resistant walking surfaces—D1P2(c)(i)

People moving on stairways and ramps should not slip and fall. This is a particular issue during an emergency.

Handrails—D1P2(c)(ii)

Handrails may be necessary to assist people using stairways and ramps, particularly in helping them maintain their stability.

Landings for stairways and ramps—D1P2(c)(iii) and (iv)

Under D1P2(c)(iii) and (iv), it is necessary to provide landings for ramps as well as stairways. As with stairways, the landings on a ramp are used as a place to rest when necessary. Landings at doorways provide a level plane from which doors may be safely opened.

Safe passage on stairways—D1P2(c)(v)

D1P2(c)(v) requires that a stairway must be suitable for the safe passage of people, and appropriate to the nature, volume and frequency of use. This is a reference to the riser and going of the treads, and the width of the stairway. Hence the rise, going and width may differ between buildings as long as a safe passage is provided.
