This section describes additional requirements for BSL33 and ABSL3 facilities. These additional requirements provide greater level of safety and reliability of operation. BSL3 Laboratory Power 10.9.1. a) Electrical Servicee (1) Buildings other than NIH Bethesda campus shall have minimum two dedicated utility services, physicallyy separated in different duct banks and different manholes. Thesee dedicatedd services shall be fed by different primary substations or by one double endedd utility substation, which is fed by two dedicated utility service lines that do not servee any other facility. Each required electric service to the facility shall be sized to handle 100% of the design load (i.e. 2N redundancy). The customer rather than the utility company should own the onsite mediumm voltage distribution including Medium Voltage (MV) / Low Voltage (LV) transformers. When customer owned distribution system installation is not possible, coordinate with the local utility company to ensure that they provide electrical distribution system that meets the facility s requirements. (2) For non-nih Bethesda, Maryland campus BSL3/ABSL3 projects with low voltage double ended switchgear, an automatic main-tie-main breakerr configuration is acceptable. The switchgear shall be metal clad compartmentalized type with each breaker capable of being racked out and replaced with the switchgear energized. BSL3 & ABSL3 Biocontainment 55 56 57 58 64 65 61 62 63 64 65 66 67 68 69 70 71 72 83 84 85 76 77 78 104 105 106 107 108 109 85 106 107 108 109 110 91 92 93 94 95 96 97 This is to increase reliability of electrical services. This provides the owner greater control over the selection of the equipment and aids maintenance of the equipment. Electrical demand of the facility may considerably exceed the utility s own engineering and construction standards. As a result, coordination with utility company is critical in providing reliable electrical service. This is to increase reliability of electrical services as tie breakerr closes to allow transfer of electric power to other available electrical service when one of the main circuit breakers opens. 1

(4) Locate distribution equipment, such as MV switches and transformers, in a secure location. (5) Reliability: The A/E shall evaluate and minimize single points of failure for all projects. (6) Downstream electrical distribution from switchgear to critical areas, such as mechanical support rooms with redundant motors in each set, shall comprise pairs of distribution switchboards/panelboards, each fed from a separate side of the switchgear, to supply approximately half of each set of motors. Where possible, provide separate feeders to packaged units with multiple motors, i.e. a separate feeder for each motor. 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 This is to protect electrical service feeders from vandalism and natural disasters such as high winds, thunderstorms and falling tree branches. This is to ensure electrical service equipment is protected from physical damage, vandalism or compromise. This is to preclude outage due to a single point of failure. This is to ensure that critical equipment remains operational when one of the service feeders fail. b) Standby Power Requirements (1) In addition to the loads listed in Section 10.3 - Emergency Power, connect the following loads to the standby electrical systems: i) Critical support fan coil units. ii) Receptacles serving selected equipment. iii) Environmental rooms. iv) General lighting. v) Laboratory air compressors. vi) Sterilizers. vii) Supplemental heating/cooling. viii) Water heaters. (2) As determined per program basis, recommend connecting the following loads to the standby electrical system: i) Freezers/Refrigerators/Environmental rooms, other than high value specimen units. ii) Distilled water systems. iii) General laboratory receptacles. iv) Heat-reclaim systems. v) Imaging equipment. vi) Task lighting. vii) Vacuum pumps. 2

(4) Provide a local generator dedicated to the facilityy to provide emergency/standby power; however, a remote generatorr farm (with redundant feeders) may also be acceptable. (5) Provide a load bank (including a connection point suitable for use for a portable generator) for all BSL3 facilities for periodic testing of generator. c) Uninterruptible Power Supply (UPS) (1) A central UPS system or a number of local UPSs may be required to back-up all building wide low voltage systems that are essential for containmen operation and for critical BSL3/ABSL3 specific loads.
