CHAPTER IX
TECHNICAL SPECIFICATIONS OF AIR CONDITIONING SYSTEMS
9.1 GENERAL PROVISIONS
The air conditioning system in the BSL-2 laboratory zone and ABSL-2 Enhanced vivarium zone must be designed, provided, installed, tested and handed over in a ready-to-operate condition that meets all biosafety, work safety and research integrity requirements. The air conditioning system must ensure that air flow is controlled, pressure relations between spaces are maintained, cross-air mixing between risk zones is prevented, and exhaust air is released through a safe filtering stage without creating a risk of releasing biological agents into the environment.
The system must be able to operate stably for 24 hours per day under full load and partial load conditions, including when there is a power interruption or component failure. Any replacement of high efficiency filters on all exhaust lines must use a closed replacement system to prevent exposure to personnel and the environment. No recirculation of air from the laboratory room and vivarium to the supply system is permitted.
The air conditioning system must be integrated with the building management system for the purposes of pressure monitoring, air flow control, safety alarms, historical recording and safety audits. The design, implementation and testing of air conditioning systems must be guided by biosafety standards and international ventilation standards that apply to laboratory facilities with a biosafety level.

Any deviation from these provisions is not permitted and must be corrected by the provider until operating conditions are achieved that meet biosafety requirements and are declared passed by an independent tester.
9.2 TECHNICAL REQUIREMENTS FOR BSL-2 and ABSL-2 ENHANCED AIR CONDITIONING SYSTEMS
1) Air Flow Requirements and Pressure Relations The air conditioning system must guarantee:
● Air flow moves from clean areas to the dirtiest areas according to biosafety principles.
● There is no backflow from high-risk rooms to lower-risk rooms
● The pressure relationship between the BSL-2 and ABSL-2 Enhanced laboratory spaces is maintained stable at all times, including under conditions of load changes or door movements.
● Differential pressure values ​​must be able to be monitored continuously and recorded through the building management system.
● A pressure loss prevention system must be in place to prevent undetected deviations.

2) Filtration Requirements for Supply Air and Exhaust Air
● The supply air to the laboratory room must be equipped with initial and intermediate stage air filters according to the filtration class applicable to biosafety laboratories.
● Exhaust air from laboratory rooms and vivariums must pass through high-efficiency particulate filters.
● High-efficiency particulate filtration must include a closed replacement system to prevent exposure.
● No recirculation of laboratory air back into the supply system is permitted.
● The exhaust air line must be released to the outside air in a discharge position that does not pose a risk of exposure or re-entrainment.
3) System Integration and Control Requirements
● All pressure, temperature and flow measurement devices must be integrated into the building management system to support monitoring, safety alarms, historical recording and biosafety audits.
● Air conditioning systems must be equipped with automatic controls that prevent critical parameters from drifting undetected
● Mechanical controls and automation must be compatible with electrical systems, emergency protection and power backup systems.
● Operations should not rely on manual intervention to maintain basic laboratory safety.
4) Testing, Verification and Operational Feasibility Requirements
● All design, installation and operation of air conditioning systems must be verified through design testing, installation testing and operational testing before being declared fit for use.
● Mandatory testing includes air flow adjustment and balancing, integration testing with building management systems, as well as robustness testing against failure scenarios.
● Final testing must be carried out by an independent examiner with international recognition.
● The system can only be considered to meet the requirements if all test results are declared passed, proven through official documentation, and submitted as part of the handover process.
5) Requirements for Operational Reliability and Resistance to Disturbances
Air conditioning systems in BSL-2 and ABSL-2 Enhanced zones must have a level of reliability that ensures that the biological containment function is not lost in the event of operational disruption. The minimum conditions that must be met include:
● The system must be able to operate stably under full load and partial load conditions without causing deviations in the pressure relations between spaces.
● In the event of failure of any component (e.g. fan, controller, or heat sink), the system must have fail-safe settings that prevent negative pressure loss or air backflow.

● The system should not rely on manual intervention to maintain basic laboratory safety functions; durability must be achieved through engineering design, not operator operations.
● In the event of a power loss, a connected backup system or other protection mechanism must ensure that the pressure connection remains safe until the power supply returns to normal.
● Any post-disturbance recovery mechanism must not result in pressure, flow, or vibration surges that have the potential to harm experimental animals, test materials, or the safety of laboratory personnel.
