Beryllium is used primarily in the medical, aerospace, electronics, telecommunications, and defense industries as an alloy in metal, usually copper. Workers in these industries may become exposed to beryllium through inhalation of airborne particles or direct skin contact, which can cause an immune response leading to beryllium sensitization.

What Do YOU Know About OSHA's New Beryllium Standard?

It was determined that OSHA's original permissible Beryllium exposure limit was outdated and ineffective to prevent diseases associated with this element. The catalyst for the enforcement is due to a consensus in the scientific community that there needs to be more protective measures in place. The original compliance date of March 12, 2018 has been currently extended to May 11th, 2018.

Jan 26, 2017 · Less than a year after the new silica dust standard, OSHA has issued a final rule on beryllium exposure. The new standard cuts the 8-hour permissible exposure limit (PEL) for beryllium to one-tenth of the previous limit, from 2.0 micrograms/m 3 to 0.2 micrograms/m 3. It also sets the 15-minute short-term exposure limit (STEL) to 2.0 micrograms/m 3.
