modified by this article, all applicable articles of this Code shall apply.

708.4 Risk Assessment. Risk assessment for critical op- erations power systems shall be documented and shall be conducted in accordance with 708.4(A) through (C).

FPN: Chapter 5 of NFPA 1600-2007, Standard on Disaster/ Emergency Management and Business Continuity Programs, provides additional guidance concerning risk assessment and hazard analysis.

(A) Conducting Risk Assessment. In critical operations power systems, risk assessment shall be performed to identify hazards, the likelihood of their occurrence, and the vulnerability of the electrical system to those hazards.

(B) Identification of Hazards. Hazards to be considered at a minimum shall include, but shall not be limited to,

the following:

(1) Naturally occurring hazards (geological, meteorological, and biological)

(2) Human-caused events (accidental and intentional) [1600:5.3.2]

(C) Developing Mitigation Strategy. Based on the results of the risk assessment, a strategy shall be developed and implemented to mitigate the hazards that have not been sufficiently mitigated by the prescriptive requirements of this Code.

708.5 Physical Security. Physical security shall be pro vided for critical operations power systems in accordance with 708.5(A) and (B).

(A) Risk Assessment. Based on the results of the risk assessment, a strategy for providing physical security for critical operations power systems shall be developed, documented, and implemented.

(B) Restricted Access. Electrical circuits and equipment for critical operations power systems shall be accessible to qualified personnel only.

708.6 Testing and Maintenance.

(A) Conduct or Witness Test The authority having juris- diction shall conduct or witness a test of the complete system upon installation and periodically afterward.

(B) Tested Periodically. Systems shall be tested periodically on a schedule acceptable to the authority having jurisdiction to ensure the systems are maintained in proper operating condition.

(C) Maintenance. The authority having jurisdiction shall require a documented preventive maintenance program for critical operations power systems.

FPN: For testing and maintenance procedures, see NFPA 70B-2006, Recommended Practice for Electrical Equip- ment Maintenance.

(D) Written Record. A written record shall be kept of such tests and maintenance.

(E) Testing Under Load. Means for testing all critical power systems during maximum anticipated load condi tions shall be provided.

FPN: For testing and maintenance procedures of emergency power supply systems (EPSSs) that are also applicable to COPS, see NFPA 110-2005, Standard for Emergency and Standby Power Systems.

708.8 Commissioning.

(A) Commissioning Plan. A commissioning plan shall be developed and documented.

FPN: For further information on developing a commissioning program see NFPA 70B-2006, Recommended Practice for Electrical Equipment Maintenance.

(B) Component and System Tests. The installation of the equipment shall undergo component and system tests to ensure that, when energized, the system will function properly.

(C) Baseline Test Results. A set of baseline test results shall be documented for comparison with future periodic maintenance testing to identify equipment deterioration.

(D) Functional Performance Tests. A functional perfor- mance test program shall be established, documented, and executed upon complete installation of the critical system in order to establish a baseline reference for future performance requirements.

FPN: See Annex F for more information on developing and implementing a functional performance
