Silica exposure assessment
Countertop fabricators, foundries, concrete products and glass plants carry O. Reg. 490/09 duties for silica. We write the assessment with your JHSC, set up the control program and run the air monitoring.
Why silica is in focus
Engineered stone can be up to 95% silica, and Ontario's Ministry of Labour issued a safety alert on silica exposure during countertop manufacturing and installing in 2023, updated in May 2025.
