Facilities used for beryllium work should be designed to minimize the spread of beryllium aerosols and to minimize beryllium contamination and opportunities for beryllium exposure. Therefore, such facilities have the following features:

* Eyewashes and safety showers shall be provided where operations are done routinely in which eye or skin contact with dust or splinters is possible. Requirements for training the users of eyewashes/safety showers are found in Section 3.1.3 of Document 10.2 (for non-laboratory situations), and Section 3.2.6 of Document 14.2 (for laboratory situations). Requirements for testing safety showers/eyewashes are specified in Appendix B of Document 14.1. Engineering specifications are found in LLNL Facility Standard PEL-M-11610, "Emergency Eyewash and Shower Units."

When a regulated beryllium work area needs to be established (see Section 3.5.7), the change room and showers should be located as close as possible, and preferably adjacent, to the regulated area or located in such a manner that beryllium contamination is not spread throughout the facility or to other workers. The ES
