OSHA Seeks Silica Standard Feedback

Comments needed regarding engineering and work practice control methods in the construction industry.

OSHA is considering revising Table 1 of its Respirable Crystalline Silica Standard for Construction.

The agency is seeking comments and feedback on engineering and work practice control methods to effectively limit exposure to silica for the equipment and tasks. It is also requesting information about other construction equipment and tasks that generate silica that it should consider adding to Table 1, along with information about their associated engineering and work practice control methods.

Among the revision consideration is the revision of paragraph (a)(3) of the Respirable Crystalline Silica Standard for General Industry to broaden the circumstances under which general industry and maritime employers would be permitted to comply with the silica standard for construction as an alternative to the general industry standard.

Information submitted will allow OSHA to consider new developments and enhanced control methods for equipment that generates exposures to silica, and provide additional data on exposures to silica from equipment and tasks using a variety of control methods under different workplace conditions. Expanding Table 1 to include additional engineering and work practice control methods, equipment, and tasks could provide employers with more flexibility and reduce regulatory burdens while maintaining protections for employees.

If information submitted in response to this request indicates that revisions to the silica standards are needed, the agency will then publish the proposed revisions in the Federal Register for public comment.

Comments must be submitted by November 13, 2019. Comments and materials may be submitted electronically at, the Federal e-Rulemaking Portal, or by facsimile or mail. See the Federal Register notice for submission details.  

Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA’s role is to help ensure these conditions for American working men and women by setting and enforcing standards, and providing training, education, and assistance.
