08 Oct OSHA Rule: Respirable Crystalline Silica
On March 25, 2016, the Occupational Safety and Health Administration
(OSHA) issued a final rule regarding respirable crystalline silica. Under
this rule, employers are subject to new standards for protecting
workers. The rule became effective on June 23, 2016. However,
employers in the construction industry had until Sept. 23, 2017, to
comply with the rule. Employers in the maritime and general industries
had until June 23, 2018, to comply.
The rule includes standards that dramatically reduced the permissible
exposure limit (PEL) for respirable crystalline silica to 50 micrograms per
cubic meter of air (50 μg/m3). The rule also requires employers to
implement specific measures to protect workers.
