On 13 December 2023, WHS ministers representing the Commonwealth, states and territories agreed to Safe Work Australia’s recommendation to prohibit the use of engineered stone to protect thousands of workers from respirable crystalline silica (silica dust).
Silica dust is generated in high levels when workers cut, shape, or polish engineered stone. Exposure to silica dust from engineered stone has led to a rapid increase in the number of workers developing the serious lung disease silicosis in Australia.
The prohibition will ban a person conducting a business or undertaking (PCBU) from carrying out work, or directing or allowing a worker to carry out work, on or with engineered stone. This includes manufacturing, supplying, processing and installing engineered stone.
Next steps
Safe Work Australia will draft amendments to the model WHS Regulations prohibiting the use of engineered stone which will be provided to WHS ministers.The prohibition will not apply to the repair, minor modification, removal or disposal of engineered stone installed prior to the prohibition. For the amendments to the model WHS Regulations to apply, each jurisdiction will need to implement them separately through amendments to their jurisdictional WHS regulations.
Safe Work Australia will develop a national framework to ensure anyone working with engineered stone products installed prior to the prohibition is doing so safely.
Safe Work Australia will also develop guidance to support PCBUs and workers understand how amendments to the model WHS Regulations will affect them and help them prepare for the changes.
Before a prohibition comes into effect
Until the prohibition of engineered stone comes into effect, workers and businesses can continue to work with engineered stone in a controlled way.
Under the model WHS Regulations, if you are cutting, grinding, trimming, sanding, abrasive polishing or drilling engineered stone using power tools or other mechanical plant, you must use one of the following:
- a water suppression (wet cutting) system
- an on-tool dust extraction system, or
- local exhaust ventilation system.
All workers who process engineered stone must also be provided with and wear respiratory protective equipment.
See our resources on working safely with engineered stone for more information.
When a prohibition comes into effect
Jurisdictions have committed to implementing amendments to their jurisdictional laws to prohibit the use of all engineered stone.Jurisdictions will manage arrangements for working with engineered stone products installed prior to the prohibition on the basis of a national framework developed by Safe Work Australia.
