Who is affected by the Construction Standard?
Effective 9/23/2017, OSHA's Respirable Crystalline Silica standard for construction requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers. Exposure can occur during common construction tasks such as using masonry saws, grinders, drills, jackhammers and handheld powered chipping tools; operating vehicle-mounted drilling rigs; milling; operating crushing machines; and using heavy equipment for demolition or certain other tasks.
The construction standard does not apply where exposures will remain low under any foreseeable conditions; for example, when only performing tasks such as mixing mortar; pouring concrete footers, slab foundation and foundation walls; and removing concrete formwork.
What does the standard require?
The standard requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers. Regardless of which exposure control method is used, all construction employers covered by the standard are required to:
Table 1, the employer shall fully and properly implement the engineering controls, work practices, and respiratory protection specified for the task. Compliance with Table 1 is upon company discretion and list of tasks should not be viewed as all inclusive.
