OSHA issued its final rule on beryllium, which is a metal that can cause cancer and other health issues when inhaled or absorbed into the skin, on Jan. 9, 2017.

Because the rule was initially met with opposition and controversy, the agency delayed its enforcement on several occasions. In June 2017, OSHA also announced that it would not enforce the final rule’s standards, other than the new Permissible Exposure Level (PEL)and Short Term Exposure Limit (STEL), for construction or shipyard employers. OSHA also issued a direct final rule to clarify portions of the final rule on May 7, 2018.
