It may not be implemented for convenience or expedience. The criteria identified in Fed/OSHA 1910.333(a)(1) and in this specification shall be followed. All others will require a formal electrical shutdown. Removal and installation of all bolt-on circuit breakers shall be done during a formal electrical shutdown. The request for hot panel work may be originated by: (a) the contractor through the assigned engineer responsible for the project which requires the hot panel work, (b) the construction coordinator through the engineer responsible for the project which requires the hot panel work, or (c) the electrical engineer responsible for the building. All requests shall be approved by the electrical engineer responsible for the building and then forwarded to the Facilities Engineering Manager for approval. (The Facilities Engineering Manager may delegate this approval authority to qualified Facilities Engineers within the Facilities Engineering Department). The request will include justification, panel number, panel schedule, area affected, contractor P & C, T & M, or PO number and the scope of work to be performed." It will be mandatory that the requester of the work be present during the performance of the hot panel work. Delegation of this responsibility must receive additional approval. a. A panel is an electrical distribution panel which contains circuit breakers/switches/fuses and does not include equipment control panels, terminal panels, junction boxes, etc. b. All hot circuits in all types of panels shall be adequately protected with temporary shields while work is occurring. c.

D. 16010-rev1 Additional Requirements: High Voltage Power (Above 600V) 16010 - 8 September 2011 SECTION 16010 ELECTRICAL - GENERAL PROVISIONS 1. Written procedures are required for all work on high voltage circuits. Switching orders (procedures) written to ensure that all energized circuits entering equipment, or an area in which work is to be done, are opened at a location remote from the work area. Each step required to take highvoltage equipment out of service is to be listed and followed sequentially. Switching orders must contain, as a minimum: a. Employment of lockout/tagout for each disconnecting device b. Testing of all exposed terminals, busways, and connections with a "glowtector" or "tic-tracer" (or equivalent testing device) after the equipment has been de-energized, and before grounds are applied c. A list of all tools required for the job d. Grounding of all exposed circuits with a ground set after the testing device indicates there is no potential present e. Isolation from backfeeds from alternate power sources, emergency power supplies, or electronically coupled signals f. Notification of personnel potentially affected by the work (but not involved) prior to power shutdown, and again prior to power restoration g. Compliance with the location's procedures for control of hazardous energy and electrical safe work practices by any personnel not involved in the initial performance of the switching orders Such activities could include, for example, cleaning of high-voltage switchgear or evaluating and adjusting terminations 2. Switching orders signed by the originator, and reviewed by the supervising individual and high-voltage technician. 3. Restoration of power may be treated as a continuation of the original order, or as a separate order. The restoration procedure is to list the step-by-step process to: a. Verify that all personnel involved have completed their work and have returned to a safe area b. Check for removal of all tools, tags, locks, grounds c. Perform "high-pot" or phasing tests, where applicable d. Secure panels and covers e. Implement switching operations 4. In emergency situations formal switching orders might not be appropriate. In such situations, switching and repairs may be limited to the minimum necessary to eliminate any hazard exposure to personnel or property. The high-voltage technician and the individual supervising must agree on the appropriate actions before each step is taken. The supervisor should have the authority to make necessary emergency decisions. Written procedures are required to complete work beyond the initial response to an emergency. 5. Grounding Procedures a. Determination made that equipment is de-energized before grounds are applied 16010-rev1 16010 - 9 September 2011 SECTION 16010 ELECTRICAL - GENERAL PROVISIONS b. Test equipment approved for high voltage use only should be used on an area which has been isolated by opening breakers or disconnects between the equipment and all sources of power c. Test equipment approved for high voltage use only should be applied to all exposed terminals and conductors in the equipment to verify de-energization d. Using a "hot stick," the other end of the grounding set is touched to all exposed terminals and conductors, after which the ground clamps are to be firmly attached to all phase terminals or conductors e. Use of protective grounding equipment capable of conducting the maximum fault current available at the point of the system being grounded for the time necessary to clear the fault. Determination of the required ground conductor size must be made by a competent individual. In no case is the protective grounding equipment to have an amperage capacity less than that provided by a No. 2 American Wire Gauge (AWG) copper conductor. 6. Design, installation, modification, or extension of power distribution systems in compliance with applicable regulatory or national consensus standards or practices.

Individuals performing work on high-voltage systems must not wear clothing that, when exposed to electric arcs or flames, could increase the extent of any injury. Avoid use of acetate, nylon, polyester and rayon fabric (alone or in blends) 10. Conduct job briefings prior to the start of high-voltage operations each day or shift. Additional briefings are required whenever changes occur which affect the safety of the operations. Briefings are to include: Sequence of operations for the project Written operating procedures for each assignment Test equipment and personal protective equipment to be used Identification of potential hazards and their potential impact to personnel performing the work Discuss all elements of the job (regardless of the previous experience and training of the personnel involved) Resolve all questions before the work proceeds 16010-rev1 16010 - 10 September 2011 SECTION 16010 ELECTRICAL - GENERAL PROVISIONS 11.

Individuals entering enclosed electrical spaces such as high-voltage manholes and vaults shall be in compliance with the HGST safety manual requirements for confined space entry. 14. Periodic inspection of high-voltage work shall be conducted by someone other than those engaged in the work to ensure that safe work procedures, practices, and use of personal protective equipment are being implemented. Documentation of the inspection should be noted on the switching orders. 15. High-voltage testing includes, as a minimum, the following work practices: Guarding of permanent test areas with walls, fences, or barriers Control of access to field test areas through the use of signs, physical barriers or barricades, or by assigning an observer to monitor the area Routine safety checks of the test area by the test operator in charge Grounding practices in compliance with applicable national standards or practices 16. All employees working with high voltage will be current in cardiopulmonary resuscitation (CPR) 10.10 EXISTING CABLES Existing cables above ceilings, in wall or under raised floors are critical to HGST operations.
