* Building components (e.g., floors and walls) that are nonporous (for ease of decontamination), to the extent feasible.

* A facility layout that enables non-beryllium workers to enter and pass between non-beryllium work areas in the facility without entering a beryllium work area.

* 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

3.8 Housekeeping

Beryllium work areas shall be kept as clean as the nature of the work allows during operational periods. The work area shall be cleaned at the conclusion of work. [The interior of a system (e.g., enclosure, glove box, chamber, or ventilation system) designed to contain beryllium contamination is not subject to this cleaning and sampling requirement.] Cleaning shall use techniques (e.g., wet methods or HEPA vacuuming) that do not produce airborne dust. Equipment used for cleaning beryllium-contaminated areas shall not be used for nonhazardous materials. Such equipment shall be labeled as beryllium contaminated using the label shown in Figure 3.

During nonoperational periods, beryllium work areas shall have residual surface contamination verified to be less than 3 µg Be/100 cm2 based on a routine sampling protocol that meets Appendix C guidelines. Sampling shall be conducted as often as necessary to ensure 95% confidence in meeting the housekeeping standard.

A nonoperational period is defined, based on the nature of the work, as the period commencing at either of the following:

o For ongoing, routine operations (i.e., production-type activities)--The end of the work shift or shifts, if work extends over one more consecutive shifts.

o For specific jobs (i.e., non-production or isolated activities)--The conclusion of the work, even if the work extends over 2 or more days. For long-term operations, the first definition applies.

3.9 Shipment and Receipt of Potentially Beryllium-contaminated Items

Operations involving shipment or transfer of potentially beryllium-contaminated items are subject to all the controls established in this document to minimize worker exposure to beryllium and to minimize the opportunities for exposure.

Classified beryllium parts shall be handled in accordance with this section when there is a potential for exposure to beryllium. See MDD Procedures Manual, Section 302.17, "Beryllium," UCRL-MA-124100 (UCNI), Materials Management Material Control and Accountability Manual, Volume A, "Material Control and Accountability Plan;" and Safeguards and Security Program Guide for specific requirements for classified parts.

Prior to shipment or transfer, potentially beryllium-contaminated items shall be cleaned to the extent practical taking into consideration the nature of the item and its subsequent use. Shipment and receipt of an item that is potentially contaminated with beryllium, or that has uncharacterized beryllium contamination, shall be handled to minimize the potential for exposure to airborne beryllium. The surface criteria standards listed in Table 2 in Section 3.3 of this document shall apply, except when:

* The item is too fragile to be swiped.
