Beryllium article

A manufactured item that is formed to a specific shape or design during manufacture, that has end-use functions that depend in whole or in part on its shape or design during end use, and that does not release beryllium or otherwise result in exposure to airborne concentrations of beryllium under normal conditions of use. Further information, including examples, is provided in Section 3.14 of this document.

Beryllium-associated worker

A current worker who is or was exposed or potentially exposed to airborne concentrations of beryllium at a DOE facility, including:

1. A beryllium worker.

2. A current worker whose work history shows that the worker may have been exposed to airborne concentrations of beryllium at a DOE facility, including workers who self-identify as having past exposure.

3. A current worker who exhibits signs or symptoms of beryllium exposure.

4. A current worker who is receiving medical removal protection benefits.

Beryllium emergency

Any occurrence (including, but not limited to, equipment failure, container rupture, or failure of control equipment or operations) that results in an unexpected and significant release of beryllium at a DOE facility.

Beryllium lymphocyte proliferation test (Be-LPT)

A screening test to measure an individual's immune system sensitivity to beryllium metal.
