ARC-FLASH HAZARD. A dangerous condition associated with the release of energy

caused by an electric arc. [IEEE 1584-2002]

30.

ARC RATING. The maximum incident energy resistance demonstrated by a material (or

a layered system of materials) prior to breakopen or at the onset of a second-degree skin

burn. Arc rating is normally expressed in cal/cm2. [NFPA 70E]

31.

ASSESSMENT. A review, evaluation, inspection, test, check, surveillance, or audit, to

determine and document whether items, processes, systems, or services meet specific

requirements and are performing effectively. [DOE O 414.1B]

32.

ASSETS. See Physical Assets. [DOE G 433.1-1]

33.

ASSET MANAGEMENT SYSTEMS. Processes and/or procedures that are employed

for non-programmatic management of a facility or physical asset. [DOE G 433.1-1]

34.

AUDITABLE DATA. Information which is documented and organized in a readily

understandable and traceable manner that permits independent auditing of inferences or

conclusions based on the information. [DOE O 5480.EIS] [EH62dd1]

AUTHORITY. The basis under which a DOE employee is empowered to take an action.

AUTHORIZATION AGREEMENT. A documented agreement between DOE and the

37.

contractor for high-hazard facilities (Category 1 and 2), incorporating the results of

DOE's review of the contractor's proposed authorization basis for a defined scope of

work. The authorization agreement contains key terms and conditions (controls and

commitments) under which the contractor is authorized to perform work. Any changes to

these terms and conditions would require DOE approval. [DNFSB/TECH-16]

38.

AUTHORIZATION BASIS. Those aspects of the facility design basis and operational

requirements relied upon by DOE to authorize operation. These aspects are considered to

be important to the safety of facility operations. The authorization basis is described in

documents such as the facility Safety Analysis Report and other safety analyses; Hazard
