1 Please note, the heights are measured vertically from the surface beneath, except for stairways where the height must be measured vertically from the nosing line of the stair. A transition zone can also be incorporated where the barrier changes height from 865 mm on a stair flight or ramp to 1 m at a landing or floor.2 The maximum 125 mm barrier opening for a stairway is measured above the nosing line of the stair treads.
