US DOL Launches Initiative to Protect Workers From Silica Dust

The U.S. Department of Labor's Occupational Safety and Health Administration launched a new initiative focused on enhancing enforcement and providing compliance assistance to protect workers against silica dust exposure.

OSHA and the National Institute for Occupational Safety and Health identify silica dust exposure as a health hazard for workers involved in manufacturing, finishing and installing natural and manufactured stone, which includes the man-made, engineered artificial or cultured types. When inhaled, very small crystalline silica particles expose workers to the risk of silicosis, an incurable, progressively disabling and sometimes fatal lung disease. Unsafe silica dust exposure can also lead to chronic obstructive pulmonary disease or kidney disease.

“Many workers in the engineered stone industry are experiencing illnesses so severe that they’re unable to breathe—much less work a full shift—because of their exposure to silica dust,” explained Assistant Secretary for Occupational Safety and Health Doug Parker. “Among them is a 27-year-old worker in California who went to an emergency room with shortness of breath in 2022 and whose lung biopsy later revealed he had silicosis. Since then, he has been on an oxygen tank and unable to support his wife and three young children financially.”

Supplementing OSHA’s current National Emphasis Program for Respirable Crystalline Silica, this initiative will focus enforcement efforts on industry employers to make sure they’re following required safety standards and providing workers with the protections required to keep them healthy. It establishes procedures for prioritizing federal OSHA inspections to identify and ensure prompt abatement of hazards in covered industries where workers face exposure to high levels of silica dust.

As part of the initiative, OSHA is sending affected employers and stakeholders information on the initiative, including fact sheets on dust control methods and safer work practices for engineered stone manufacturing, finishing and installation operations.
