Australia's workplace ministers have agreed to implement a national ban on engineered stone, over concerns its use has led to a surge in silicosis cases among workers.
The underlying point has some validity though. Many materials contain silica, even tiles, although not the same amount. Here are some other examples.
ceramic tiles: 5% to 45%
engineered stone: 80% to 95%
Sandstone: 70% to 90%
Granite: 25% to 60%
Slate: 20% to 40%
autoclaved aerated concrete: 20% to 40%
concrete: less than 30%
brick: 5% to 15%
The cancer council of Australia says “there is currently no evidence to suggest a safe level of silica dust exposure”.
If there is no safe level of silica, then by extension
presumably this would rule out many other products containing silica.
There are mitigation strategies, however they seemingly weren’t good enough for engineered stone, and presumably again by extension many other materials high in silica.
It’s just not clear to me why engineered stone is banned but many other materials potentially high in silica are for choice of better words let off the hook.
But broadly, engineered stone is significantly different because of both its composition and how it’s used. The proof of the pudding, though, is that with its rise in popularity we’ve also seen the rise of these ‘acute accelerated’ cases of silicosis.)
