Regulators move to curb silicosis risks from engineered stone

Regulators in the United Kingdom and the United States are taking action to address a rise in silicosis cases linked to the fabrication of engineered stone. In the UK, the Health and Safety Executive (HSE) has issued new guidance warning against dry cutting engineered stone due to the risks of respirable crystalline silica dust exposure. This follows more than 50 confirmed cases and four deaths in the country. Experts have compared the situation to the asbestos crisis, with some calling for a total ban similar to policies in Australia.

In the United States, California regulators are moving toward a ban on engineered stone products containing more than 1% crystalline silica. This follows a surge in silicosis cases among stone fabrication workers. Engineered stone poses a significantly higher risk than natural stone; while natural granite typically contains 10–45% crystalline silica, engineered stone can contain up to 95%. This high concentration can lead to hazardous airborne levels during routine cutting and polishing if adequate engineering controls are not in place.
