The article claims “despite taking precautions”, but practically everyone I know in the trades who works with this stuff doesn’t wear a mask when cutting it. When I was a tradey in NZ (painting) we would often see guys refinishing concrete floors mask-free, just inhaling all of the concrete particulate all day. When you are 19, you would rather look cool even when nobody is around than wear a mask, because you are going to live forever! Rather than ban the product (placing more pressure on natural stone quarries and decemate an entire industry of producers) they should be introducing mandatory safety procedures (as has been done in many places of the world with roofing I.e. wearing harnesses). Make it an OSHA violation to cut stone indoors, without dust collection or mitigation and without a mask. Violators get fines (like they do for other OSHA violations), and while not perfect, the culture slowly changes.
