Beryllium  the Element The purpose of this website is to provide employers with insight, guidance and tools for meeting the requirements of the OSHA Beryllium Standard (1910.1024).

NOTE: On April 24, 2018, the Occupational Safety and Health Administration (OSHA) and Materion along with other petitioners signed an important agreement where OSHA will initiate rulemaking to make changes to the OSHA Beryllium Standard for General Industry (29 CFR 1910.1024) issued January 9, 2017. Materion stronugly recommends you review and use the redline version, which contains the proposed changes to the OSHA Beryllium Standard, available on the Materion website until such time as the proposed changes become final. As a result of the rulemaking process, the final content of OSHA’s regulatory changes could end up being different than this redline version. We believe, however, following this redline version will place you in the best possible position to be in compliance with the final changes to the OSHA Standard.

The guidance provided in this website is based on the proposed changes to the OSHA Beryllium Standard. First time users of this guidance for compliance website are encouraged to follow this website in sequential order from Applicability through Recordkeeping.

Along with a lower Permissible Exposure Limit (PEL) OSHA’s final rule establishes an Action Level (AL), a Short-Term Exposure Limit (STEL) and requires employers who process beryllium-containing materials to comply with a number of additional provisions.

The following links describe what beryllium is and where it is used:

Beryllium Exposure Limits

Action Level (AL) – means a concentration of airborne beryllium of 0.1 microgram per cubic meter of air (µg/m3) calculated as an 8-hour time-weighted average (TWA).

Time-weighted average (TWA) PEL – The employer must ensure that no employee is exposed to an airborne concentration of beryllium in excess of 0.2 μg/m3 calculated as an 8‑hour TWA.

Short-term exposure limit (STEL) – The employer must ensure that no employee is exposed to an airborne concentration of beryllium in excess of 2.0 μg/m3 as determined over a sampling period of 15 minutes.

Action Level

Permissible Exposure Limit

2 as determined over a sampling period of 15 minutes

This Guidance for Compliance (GFC) website will guide you through the standard to determine which elements apply to your beryllium operations. Upon completion, you will know, not only WHAT needs to be done to meet your compliance obligations under the standard, but also, tools and documents are available for your consideration to help get you there.

Previously, in a memorandum dated March 2, 2018, OSHA delayed enforcing the general industry standard (§1910.1024) until May 11, 2018. However, under the terms of settlement agreements reached with petitioners challenging the rule, the Agency will propose to extend the compliance dates of certain requirements until December 12, 2018. Paragraphs of the standard (§1910.1024) going into effect on May 11, 2018 include (a) Scope and Application, (b) Definitions, (c) Permissible Exposure Limits, (d) Exposure Assessment, (g) Respiratory Protection, (k) Medical Surveillance, and (l) Medical Removal.

  • If required, change rooms and showers must be provided by March 11, 2019; and
  • If required, engineering controls must be implemented by March 10, 2020.
