Silica mud is a really positive mud produced when merchandise resembling bricks, concrete and pavers are reduce or drilled. Synthetic stone, which is used primarily for kitchen benchtops, is a very potent supply of silica mud.
Respiratory this mud into the lungs could cause extreme long-term injury. This may end up in respiration difficulties, scarring of the lungs (silicosis) and lung most cancers.
In our lately revealed report, we estimate that with out motion, Australian employees would develop greater than 10,000 future lung cancers and virtually 104,000 silicosis circumstances throughout their lifetime resulting from their publicity to silica mud. That is round 1% of all future lung cancers within the Australian grownup inhabitants.
Nevertheless, banning synthetic stone would scale back silica publicity and will forestall 100 lung cancers and virtually 1,000 silicosis circumstances over the lifetime of those employees.

Re-emergence of an outdated illness
Silica mud is a critical hazard in Australian workplaces. Round 7% of Australian employees are liable to respiration it in. Publicity is commonest in miners and development employees.
For the final 60 years, silicosis was very uncommon in Australia. As a result of elevated use of synthetic stone, we are actually seeing a re-emergence of this horrible illness.
In response to the resurgence of silicosis, the Australian authorities arrange a taskforce to enhance the well being and security of these working with silica mud. Its last report, from June 2021, advisable additional evaluation on how finest to guard synthetic stone employees.
That is now beneath manner, with Secure Work Australia releasing a regulatory affect assertion for session. This assertion appears to be like at a lot of choices to scale back publicity to silica and the price of these over the following ten years.
Secure Work Australia concluded these measures would solely want to avoid wasting about 5 folks a yr from silicosis to ensure that these choices to be price efficient.
Whereas it is a good begin, there’s scope to do rather more. Banning synthetic stone is among the many suggestions advised by the taskforce however not presently supported by authorities and never being thought of by Secure Work Australia.
Assessing the hurt
To estimate the hurt brought on by silica mud at work, we used a way which calculates what number of extra illness circumstances would happen in employees uncovered to silica mud in a single yr – on this case, the yr 2016.
We used previous publicity surveys and up to date reviews from New South Wales and Victoria to estimate what number of employees had been uncovered to silica mud nationwide.
Then we modelled what number of lung cancers and silicosis circumstances would happen throughout the lifetimes of those employees.
We then checked out attainable methods to scale back publicity to silica mud, together with moist reducing, lowering employee entry to dusty areas, utilizing good high quality and well-fitted respirators, in addition to banning synthetic stone.
Whereas this modelling isn’t but revealed in a peer-reviewed journal, it has been peer-reviewed by others within the area.
Lowering the hurt
We discovered banning synthetic stone may forestall 100 lung cancers and virtually 1,000 silicosis circumstances.

We additionally checked out different management measures which could possibly be carried out within the interim.
Establishing exclusion zones round areas the place synthetic stone is reduce, utilizing well-fitted respirators, wetting synthetic stone whereas reducing it, and utilizing on-tool mud extraction whereas reducing synthetic stone may forestall circumstances of lung most cancers and silicosis, however not as many as an entire ban.
Nicely-fitting respirators can cut back the danger.

Sadly, a ban on silica mud in different industries resembling mining isn’t attainable. Nevertheless, publicity may be diminished. Stopping employees from getting into areas close to crushers on mine websites would forestall 750 lung cancers and virtually 7,500 silicosis circumstances.
If we had been capable of cut back publicity within the mining business to that skilled by the overall inhabitants, we may save greater than 2,300 lung cancers and over 20,000 silicosis circumstances.
Lowering silica mud would save lives
General, making certain compliance with engineering controls and respiratory tools may forestall greater than 400 employees from creating two horrible ailments.
These circumstances can solely be prevented if there may be 100% compliance with management measures. It is a stage of compliance a lot larger than what we’re presently seeing in Australian workplaces.
A licensing system for synthetic stone companies resembling that underway in Victoria would possibly go some technique to bettering compliance, however the results of this stay to be seen.

Nevertheless, if we banned synthetic stone, we may save as much as 700 extra younger employees from creating these ailments. If we tried to eradicate silica mud publicity in different industries, we may forestall much more illness.
Clearly, rather more must be carried out to guard our employees from these finally preventable lung ailments.
