On or about May 9, 2025, at the worksite located at Highway 441 by Exit 289A, Menasha, Wisconsin; the employer did not ensure that water was applied at flow rates sufficient to minimize the release of visible dust, exposing employees to the hazards associated with respirable crystalline silica in the following instances:  a) An employee operating a walk-behind saw (Manufacturer: Diamond Products, Model: CC6571D, Equipment Identifier: 155779) to cut concrete generated visible dust clouds when used with an integrated water delivery system. The employee was exposed to a time-weighted average (TWA) of 94.0 ?g/m3 of respirable crystalline silica, approximately 1.88 times the permissible exposure limit (PEL) of 50 ?g/m3. The exposure level was derived from one sample collected over a 124-minute sampling period. b) An employee operating a walk-behind saw (Manufacturer: Diamond Products, Model: CC6571D, Equipment Identifier: 145945) to cut concrete generated visible dust clouds when used with an integrated water delivery system.
