Confinement System - doe-hdbk-1188-20060019

DOE-HDBK-1188-2006

Primary confinement . Provides confinement of hazardous material to the vicinity of its

processing. This confinement is typically provided by piping, tanks, glove boxes,

encapsulating material, and the like, along with any offgas systems that control effluent

from within the primary confinement.

Secondary confinement . Consists of a cell or enclosure surrounding the process material

or equipment along with any associated ventilation exhaust systems from the enclosed

area. Except in the case of areas housing glove-box operations, the area inside this

barrier is usually unoccupied (e.g., canyons, hot cells); it provides protection for operating

personnel.

Tertiary confinement . Typically provided by walls, floor, roof, and associated

ventilation exhaust systems of the facility. It provides a final barrier against the release of

hazardous material to the environment. [Reference Unknown]

93.

CONFINEMENT SYSTEM. The barrier and its associated systems (including ventilation)

between areas containing hazardous materials and the environment or other areas in the nuclear

facility that are normally expected to have levels of hazardous materials lower than allowable

concentration limits. [DOE O 5480.30] [EH62dd1]

94.

CONFIRMED POSITIVE TEST. For drugs, a finding based on a positive initial or screening

test result, confirmed by another positive test on the same sample. The confirmatory test must

be by the gas chromatography/mass spectrometry method. [10 CFR 707.4]

95.

CONSENT AGREEMENT. Any written document, signed by the Director and a person,

containing stipulations or conclusions of fact or law and a remedy acceptable to both the

Director and the person. [10 CFR 820.2]

96.

CONSIGNEE. The person designated in the shipping papers to receive the shipment. [DOE G

460.2-1]

97.

CONSIGNOR. The person executing the shipping papers and named as such in the shipping

papers. The consignor is in every case a shipper. [DOE G 460.2-1]

98.

CONTAINMENT SYSTEM. A structurally closed barrier and its associated systems

(including ventilation) between areas containing hazardous materials and the environment or

other areas in the nuclear facility that are normally expected to have levels of hazardous

materials lower than allowable concentration limits. A containment barrier is designed to remain

closed and intact during all design basis accidents. [DOE O 5480.30] [EH62dd1]
