The government and various professional bodies tried to enforce the use of PPE when working with this material, but there has been a housing construction boom going on and a lot of corners were cut (hah!), resulting in young immigrant workers especially turning up in hospitals with lung cancer.
No matter how carefully you cut this stuff in a shop with a filtered HVAC, water sprays, and well-fitted respirators… there’s always that customer that just needs “one quick adjustment” on-site. One quick cut turns into one per day and a weird chest pain that just won’t go away.
So it’s been banned outright.
PS: Apparently engineered stone is mostly quartz (silica), whereas other bench top materials are typically other kinds of stone that don’t cause silicosis, or nowhere near at the same rate.
