U.S. Department of Energy ORDER Washington, D.C. DOE O 420.2B Approved: 7-23-04 Certified 5-13-08 SUBJECT: SAFETY OF ACCELERATOR FACILITIES 1. OBJECTIVE. To establish accelerator-specific safety requirements which, when supplemented by other applicable safety and health requirements, will serve to prevent injuries and illnesses associated with Department of Energy (DOE) or National Nuclear Security Administration (NNSA) accelerator operations. 2. CANCELLATION. DOE O 420.2A, Safety of Accelerator Facilities, dated 1-8-01. Cancellation of an Order does not, by itself, modify or otherwise affect any contractual obligation to comply with the Order. Cancelled Orders that are incorporated by reference in a contract remain in effect until the contract is modified to delete the references to the requirements in the cancelled Orders. 3. APPLICABILITY. a. Primary DOE Organizations, Including NNSA Organizations. Except for the exclusions in paragraph 3c, this Order applies to any of those Primary DOE Organizations involved with accelerator facilities (accelerators and their operations) or modules thereof, including injectors, targets, beam dumps, detectors, experiments, experimental halls, etc. (See Attachment 1 for a complete list of Primary DOE Organizations. This list automatically includes Primary DOE Organizations created after the Order is issued.) The Administrator of NNSA shall assure that NNSA employees and contractors comply with their respective responsibilities under this Order. b. Site/Facility Management Contractors. (1) Except for the exclusions in paragraph 3c, the Contractor Requirements Document (CRD), Attachment 2, sets forth requirements of this Order that will apply to site/facility management contractors whose contracts include the CRD. (2) This CRD must be included in site/facility management contracts that involve the management and operation of accelerators unless superseded by an alternative standard that is in accordance with the terms of the laws, regulations, and DOE directives clause of the contracts. (3) This Order does not apply to other than site/facility management contractors. Any application of any requirements of this Order to other AVAILABLE ONLINE AT: INITIATED BY: http://www.directives.doe.gov Office of Science 2 DOE O 420.2B 7-23-04 than site/facility management contractors will be communicated separately from this Order. (4) The office identified in the responsibilities paragraph is responsible for notifying the contracting officer of which site/facility management contractors are affected. Once notified, the contracting officer is responsible for incorporating the CRD into the contracts of affected site/facility management contractors via the laws, regulations, and DOE directives clause of the contracts. (5) As the laws, regulations, and DOE directives clause of site/facility management contracts states, regardless of the performer of the work, site/facility management contractors with the CRD incorporated into their contracts are responsible for compliance with the requirements of the CRD. (a) Affected site/facility management contractors are responsible for flowing down the requirements of this CRD to subcontractors at any tier to the extent necessary to ensure the site/facility management contractors’ compliance with the requirements.

(b) Contractors must not unnecessarily or imprudently flow down requirements to subcontractors. That is, contractors will— 1 ensure that they and their subcontractors comply with the requirements of the CRD and 2 incur only those costs that would be incurred by a prudent person in the conduct of competitive business. c. Exclusions. (1) Unmodified commercially available units that are acceptable for industrial applications, including (but not limited to) electron microscopes, ion implant devices, and x-ray generators.
