Wilson, DrPH, CBSP Farhad Memarzadeh, Ph.D., P.E.July 2006Biosafety Level 3 (BSL-3/ABSL-3) containment laboratories for animals and research are the most difficult containment level facilities to design and operate. They should be certified for use before initial operation and subsequently on an annual schedule or after a program change, renovation or replacement of critical HVAC/exhaust system components (specifically fans, air valves, or fan motors) that may affect the operating environment of the laboratory.Laboratory certification is the systematic review of all safety features and processes associated with the laboratory (engineering controls, personal protective equipment, building and system integrity, standard operating procedures (SOPs) and administrative controls such as documentation and record retention systems). This validation assures that all reasonable facility controls and prudent practices are in place to minimize, to the greatest extent possible, the risks associated with laboratory operations and the use of biohazardous materials. Standardization of an initial and annual certification process for BSL-3 facilities will provide accountability that ensures proper and regular maintenance and demonstrates the use of SOPs that protect human and animal occupants, the environment and the research integrity.High containment laboratory certification helps ensure that:Appropriate site and protocol specific administrative controls and proper engineering controls are being usedPersonal protective equipment (PPE) is appropriate and undergoes regular inspection to maintain personal safety for the tasks being performedDecontamination systems for waste and other potentially infectious materials, including spill management, has been adequately considered and proper procedures are in place to mitigate environmental and personnel contaminationProper standard operating procedures (SOPs) for general laboratory safety and security, including physical, electrical, biological and chemical control mechanisms are in place.Certification of high containment laboratories will be performed by a team of professionals with experience and credentials in engineering and biosafety/occupational safety and health. DOHS will manage and perform certification of NIH intramural laboratories and other high containment facilities. When appropriate, DOHS may delegate the responsibility for providing certification of a laboratory or facility to a third party.As a part of the laboratory certification process, the Biocontainment Laboratory Certification Checklist must be completed as a retained record document. Re-certification of the facility will be performed on an annual basis, as a minimum. A comparison should be made to the baseline established during initial certification. Detailed records of the certification process and test results must be maintained to provide an accurate operations history of the laboratory.DIVISION 14: CONVEYING EQUIPMENT14 92 00 Pneumatic Tube SystemPneumatic tube system additions or changes shall use SWISSLOG parts and system components to match existing system.

Manufacturer BALL IN THE WALL:Airflow direction status shall be indicated via a visual-only primary element that does not utilize any electricity.Visual indicator shall display a degradation of the desired one directional airflow prior to a neutral or reversal of directional airflow.Direction airflow indicator shall display a self-check for failure each time the airlock or door is opened. This is accomplished by the indicating sphere rolling to its fail-safe position (corridor for negative rooms or inside room for positive rooms) when the door to the room is opened. The indicating sphere returns to its proper position (in the room for negative rooms or in the corridor for positive rooms) when the door is closed.Per NFPA, walls shall limit smoke migration, which includes any openings in walls. The primary element of the airflow direction indicator shall incorporate a means of stopping airflow through the element when the room door is closed and the room is under proper negative or positive pressure.23 21 13 HVAC Piping and PumpsInclude isolation valves for all steam traps23 21 00 Hydronic Piping and PumpsNo specific requirements at this time 23 25 00 HVAC Water TreatmentUse Neptune or equal for chemical feed for HVAC service water for closed systems23 33 00 Air Duct AccessoriesNo specific requirements at this time23 34 00 HVAC FansPLENUM FANS Use direct-driven, plenum fan units, configured for horizontal flowFan wheel shall be comprised of the following:air-foil shaped extruded aluminum bladesNon-tapered style blade retaining ring on inlet-sideHollow blade wheels with continuous welds around edgesInlet cone shall be:Spun steelManufacturer’s standard thickness for wheel sizeMatched to wheel intake rimMotor size shall be large enough so driven load will not require motor to operate in service factor range above 1.0.Enclosure Type shall be specified as one of the following:Open, Drip-Proof (OPD) orTotally Enclosed Fan Cooled (TEFC)For motors controlled by Variable Frequency Drives (VFD), premium efficiency motors, suitable for inverter duty, shall be specified.For motors controlled by Variable Frequency Drives (VFD), use ABB DrivesShaft grounding (not provided by AEGIS) shall be provided for All fans controlled by VFDs serving patient areasAll fans with motors 2 HP or greater Motor pedestal shall be specified with heavy-duty motor mounting platform with mechanical isolationInlet safety screens shall be specified as welded wire safety screens.Outlet guards shall be specified as welded wire safety screens either:Open at bottom orEnclosing fan outlet on all sidesCENTRIFUGAL EXHAUST VENTILATORSConfigured for vertical flow of relatively clean exhaust air for general ventilation applications.Belt driven only whenRequired by code for smoke removal or due to airstream medium in useCFM is too high to meet with direct driveMotor mount assemblies shall be fabricated of heavy gage galvanized steel.Motor Size: Large enough so driven load will not require motor to operate in service factor range above 1.0.Efficiency: Premium efficiency motors must be used for fans with motors of 1 HP or greater.For motors controlled by Variable Frequency Drives (VFD), use ABB DrivesShaft grounding should be provided for all fans controlled by VFDs (Do not use AEGIS)Fan locations shall allow for 36” clearances for service and maintenance.Duct connections shall allow for adequate clearances for service and maintenance.23 36 00 Air Terminal UnitsVARIABLE-AIR-VOLUME UNITS for PRESSURE-CRITICAL AREASFor areas with crucial pressure requirements (e.g., positively pressured patient rooms, negatively pressured isolation rooms, pharmacies) air valves manufactured by PHOENIX shall be used to maintain those pressure relationshipsIndependent sensors will measure room pressure and communicate to air valves (not flow sensors)Design must include this sequence: When door opens to pressure-controlled room, the air valve holds position.
