- 1m or more along the side of any roof to which public access is provided, any stairway or ramp, any floor, corridor, hallway, balcony,deck, verandah, mezzanine, access bridge or the like and along the side of any delineated path of access to a building.
- 4m or more through an openable window. (It is deemed possible for a person to fall through an openable window when a 125 mm sphere is able to pass through the window opening.)
- The height must not be less than 865mm above the nosings of the stair treads or the floor of a ramp.
- The height must not be less than 1m above the floor of any access path, balcony, landing or the like
- The height must not be less than 865mm above the floor beneath an openable window.
- Openings shall not permit a 125mm sphere to pass through the balustrade or other barrier (For stairs this is tested above the nosing line)
- When protecting a fall of 4m or more there shall be no horizontal elements within the balustrade or other barrier between 150mm & 760mm above the floor level that would facilitate climbing.
- A glass balustrade must comply with AS1288 Australian Standard AS1288-2006 (AS1288) sets out the procedures for the selection and installation of glass in buildings, subject to wind loading, human impact, and special applications such as overhead glazing, balustrades and glass assemblies.
Glass can form a structural component of the balustrade (this would be option a. above or a structural balustrade panel of glass) or the balustrade may have a structural component provided from another material such as timber or steel, with the glass acting as an infill panel only (this would be option b. above or a infill balustrade panel of glass).
a. Load supporting handrails
b. Non-load supporting handrails
c. Interlinking handrails
Load supporting handrails: the handrail is mechanically fixed to the structure, independent of the glass, but the glass may be connected to it. The handrail supports the loads. This handrail is utilised with infill balustrade panels.
Non-load supporting handrails: either the top edge of the glass acts as the handrail or the glass supports a handrail that is fixed to the glass and relies upon the glass for structural support. This handrail is utilised with structural balustrade panels.
Interlinking handrails: an interlinking handrail is only considered such when it is connected to adjacent panels of glass, or the building, where the adjacent panels are at least 1000mm wide and the balustrade consists of at least three glass panels. This requirement means that if one of the glass panels fails (breaks) the two remaining panels and the handrail must be capable of resisting the defined loads. The handrail must be designed with this in mind. This handrail is utilised with structural balustrade panels.
Therefore as required by the BCA a required balustrade, shall when incorporating glass and attempting to comply with the deemed to comply provisions of AS1288 be either:
a. An infill panel of glass, with thickness selected in accordance with table 7.3 of AS1288 and incorporating a load supporting handrail, or
b. A structural panel of glass, with thickness selected in accordance with table 7.2 of AS1288 and incorporating an interlinking handrail or load supporting handrail.
For any other required balustrade incorporating glass to comply, including systems that do not incorporate a handrail, then the requirements of Section 3 of AS1288: General Design Criteria must be satisfied. This is considered an engineered solution. And as such the site specific application of the system (NOTE: the system refers to the glass, the fixings and the handrail as applicable) shall be tested and certified as being compliant with the BCA, AS1288 and AS1170.1.
