U.S. Department of Labor safety inspectors determined that Brazilian Stone Design LLC, a Powder Springs, Georgia, stone countertop manufacturer, exposed workers to respirable crystalline silica.

The department’s Occupational Safety and Health Administration cited the employer, which fabricates and sells kitchen and bathroom countertops, with seven serious citations. The employer will pay $33,000 in penalties.

The employer was cited for allegedly exposing workers to high airborne concentrations of respirable crystalline silica and failing to require the use of respirators; perform fit testing and training for workers wearing respirators; conduct air monitoring; and administer an effective hearing conservation program.
