Do stone countertop fabricators need regular silica dust testing?

Yes, absolutely. Stone countertop fabrication - especially with engineered stone - can produce extremely high levels of RCS when cutting, grinding, or polishing.

Regular monitoring confirms whether dust controls like water suppression and LEV are working effectively. It also provides documented evidence of compliance, which is important for both legal and insurance purposes.

Even if controls appear to be working well, changes in materials, tools, or work methods can alter dust levels, so scheduled testing is essential for ongoing safety.
