* Protective clothing and equipment (Section 3.6.2, "Other Personal Protective Equipment").

Even when measurable exposures are less than the AL, steps shall be taken to reduce exposures further, if practical, although a formal program is not required. The controls in this document constitute the LLNL program to minimize worker exposure to beryllium.

3.3 Standards

The DOE, in 10 CFR 850, has established standards for beryllium airborne exposure and surface contamination allowable in DOE facilities. Additional standards are promulgated by OSHA, in 29 CFR 1910.1000, and are applicable to LLNL as Work Smart Standards. These exposure standards are listed in Table 2. The guidance provided in Appendix C is to be used for determining compliance with the standards. Sampling shall be conducted to ensure statistical confidence of at least 95% in meeting the standards.
