Homemade Calcium Silicate Board? - Forno Bravo Forum

I attempted to locate reports of lung disease among workers exposed to calcium silicate (wollastonite) but found none. However, I did come across a study focusing on workers with an average industrial exposure of nine years, which showed no increase in lung disease or any other illness. That said, one should consider that there could be concerning toxicity data available. Simultaneously, evidence for conditions like silicosis or other lung diseases from calcium silicate dust exposure should be backed by literature citations. Common sense would recommend taking precautions to avoid "excessive" dust exposure. It's also worth noting that long-term experience with dust-related diseases, such as black lung and asbestos-related mesothelioma, indicates many years of heavy industrial exposure are generally required to cause disease. I would advise the original poster (OP) that performing a week-long task that generates considerable dust, while wearing a basic cannister-style respirator, would likely involve significantly less personal safety risk than the risk associated with commuting to work that same week. Here is a reference from the CDC from 1991:

I'm not advocating a cavalier approach to dust exposure, but it's prudent to weigh perceived risks against the everyday risks we all take. Simply suggesting there might be a risk is not helpful. The essential question is the degree of risk and its comparison to the inevitable risks we face in daily life. For what it’s worth.

To further discuss the risk associated with the OP's proposed job, I tried to find reports of lung disease in workers exposed to calcium silicate (wollastonite) but could find none. I did find one study of workers with an average industrial exposure of nine years that found no increased lung disease or other illness. While it's possible that worrying toxicity data exists, it’s difficult to find evidence of silicosis or other lung diseases due to calcium silicate dust exposure without proper literature citations. Common sense would advise caution regarding "excessive" dust exposure. Moreover, long-term experiences with dust-related diseases like black lung and asbestos-related mesothelioma show that many years of industrial exposure are usually required to cause disease. I would suggest the OP, in undertaking a one-week project involving significant dust generation, wear a simple cannister-style respirator. This approach would probably pose less personal safety risk than the risk of commuting to work during the same period. Here is a reference from the CDC from 1991: https://www.cdc.gov/niosh/docs/81-123/pdfs/0094.pdf?id=10.26616/NIOSHPUB81123 I'm not recommending a dismissive approach to various dusts but believe it's useful to compare risks to the everyday hazards we encounter. Merely stating potential risks isn’t beneficial. The real question is about the level of risk and its comparison to unavoidable daily risks. For what it’s worth. Denis
