Be-LPT

See "Beryllium lymphocyte proliferation test."

Beryllium

Elemental beryllium and any insoluble beryllium compound or alloy that contains 0.1% beryllium or greater and that may be released as an airborne particulate.

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.

Beryllium work

An activity, taken for or by DOE at a DOE facility, that can expose workers to airborne beryllium--including, but not limited to, design, construction, operation, maintenance, or decommissioning--and that may involve one DOE facility or operation or a combination of facilities and operations. This term is synonymous with "beryllium activity," used in 10 CFR 850.

Beryllium work area

Any area in which beryllium use may result in personnel exposure; areas with beryllium articles only (as defined by OSHA in 29 CFR 1910.1200) are not included this definition.

Beryllium worker

A current worker who is regularly employed in a DOE beryllium activity. At LLNL, this term indicates any worker assigned to a beryllium work area or a regulated beryllium work area.

Breathing zone

A hemisphere forward of the shoulders, centered on the mouth and nose, with a radius of 6 to 9 inches.

CBD

See "Chronic beryllium disease."

CBDPP

Chronic Beryllium Disease Prevention Program.

Chronic beryllium disease

A disease of the lungs caused by the body's immune system and characterized by progressive scarring of the lungs.

Confirmed positive

Positive result based on analysis of two separate blood samples (Be-LPT or an equivalent test).

Contaminated

Presence of beryllium surface contamination in excess of 0.2 µg Be/100 cm2 or, when the visible accumulation of dust is present, in excess of the concentration (in µg Be/g of soil) of beryllium in soil at the point of release.

DOE

Department of Energy.

DOE contractor

Any entity under contract with DOE (or its subcontractor) that has responsibility for performing beryllium activities at DOE facilities. Includes LLNL and its subcontractors.

DOE facility

Any facility operated by or for DOE. Includes LLNL.

HEPA

High-efficiency particulate air (filter).

High-efficiency particulate air (HEPA) filter

A filter that traps and retains at least 99.97% of 0.3 m m monodispersed particles.

Immune response

The series of cellular events by which the immune system reacts to challenge by an antigen.

Medical Director

The physician responsible for the overall direction and operation of the site occupational medicine program. This position is referred to as the Site Occupational Medical Director in 10 CFR 850.

Medical removal protection benefits

The employment rights established by 10 CFR 850.35 for beryllium-associated workers who voluntarily accept temporary or permanent medical removal from beryllium areas following a recommendation by the Medical Director.

Non-beryllium work area

Workplaces where there is no beryllium to result in an exposure; beryllium articles may be present in such areas.

Nonoperational period

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

* 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.

* 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.

OSHA

Occupational Safety and Health Administration.

PAPR

Powered, air-purifying respirator.

PEL

See "Permissible exposure limit."

Permissible exposure limit

For beryllium, the PEL is 2 µg Be/m3 averaged over 8 hours.

Personal sample

An air sample taken in a worker's breathing zone (a hemisphere forward of the shoulders with a radius of approximately 6--9 inches) to evaluate a worker's exposure to airborne beryllium.

PPE

Personal protective equipment.

Regulated beryllium work area

An area, demarcated by the responsible employer, in which the airborne concentration of beryllium equals or exceeds, or can reasonably be expected to equal or exceed, the action level.

Removable contamination

Beryllium contamination that can be removed from surfaces by nondestructive means, such as casual contact, wiping, brushing, or washing.

Responsible employer

1. For DOE contractor employees, the DOE contractor office that is directly responsible for the safety and health of DOE contractor employees while performing a beryllium activity or other activity at a DOE facility.

2. For DOE employees, the DOE office that is directly responsible for the safety and health of DOE Federal employees while performing a beryllium activity or other activity at a DOE facility.

3. Any person acting directly or indirectly for either of the above offices with respect to the terms and conditions of employment of beryllium-associated workers.

SCBA

Self-contained breathing apparatus.

Shipment or shipping

Movement of an item over public roads.
