Raised flooring can help to differentiate your stand and hide cables. However it presents safety issues and you must ensure that your stand-builder complies with the Building Code of Australia.
The following is a summary of additional requirements, which must be met by designers and builders to ensure adequate access, mobility and to reduce the likelihood of slip and trip incidents:
- All raised floor sections or ramped edges are to be free of sharp or dangerous edges and anything that poses a trip hazard.
- Edges of thin decorative flooring such as carpet, vinyl, matting, wood or the like, are to be taped down or firmly secured.
- Flooring such as bark, pebbles,soil, railway sleepers and other loose materials are to be steady under foot and not cause a trip hazard. Regulations apply to the installation and removal of these materials from the venue floor.
Raised Floors under 115 mm in Height
- All raised floors with a height of less than 115 mm must have a clearly distinguishable ramped edge installed
- Ramped edging with a gradient no less than 1:3 is acceptable to prevent a trip hazard on standard 32 mm high raised floors; however please note that a 1:3 ramped edge does not constitute a disabled access ramp (see Disabled Access below)
- For raised floors above 32 mm and below 115 mm it is recommended that the gradient of the ramped edging is decreased to 1:8
Raised Floors over 115 mm in Height
- Where the flooring height exceeds 115mm, a step and/or series of steps should be constructed as per NCC requirements. When a step is installed, an approved stair-nosing must also be installed, as per NCC requirements for steps in public places.
- Where two (2) or more steps (risers) are provided, a handrail is to be provided to at least one side of the steps, as per NCC.
