Chat OnlineJan 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.
