A regulated beryllium work area reverts to a beryllium work area when personal air samples determine that exposures are less than the AL.

3.5.8 Labeling and Posting

All access points to a beryllium work area shall be demarcated with a sign having, as a minimum, the wording shown in Figure 1. Earlier versions of such signs having the same wording may be used if legible.

All access points to a regulated beryllium work area shall be demarcated, as required by 10 CFR 850, with a sign having, as a minimum, the wording shown in Figure 2.

All containers of beryllium, beryllium compounds, or beryllium-contaminated clothing, equipment, waste, scrap, or debris shall be labeled, as required by 10 CFR 850, with a sign having, as a minimum, the wording shown in Figure 3. In addition, labeling shall also conform to the requirements of the LLNL Health Hazard Communication Program, as specified in Document 10.2.

Items made of beryllium, beryllium alloys, or beryllium compounds that do not meet the definition of beryllium articles shall be labeled as indicated in Figure 4. When such a label affects the performance of the item or interferes with a process (e.g. machining or cleaning), the label shall be positioned so that the information is readily apparent to the user or shall be included in the work documentation.

Figure 4. Label for beryllium items.

Beryllium articles, although exempt from the requirements of 10 CFR 850, should be labeled, when feasible, to alert users to the presence of beryllium. Labels may be affixed to storage containers or enclosures for parts. The label shown in Figure 5 may be used for this purpose.

Areas where beryllium metal, alloys, or compounds are stored shall be posted prominently with the sign shown in Figure 6:
