The Importance of Redundant Systems in High-Containment Laboratory Design

In the realm of high-containment laboratories, where safety, reliability, and precision are paramount, the design and construction phases demand meticulous attention to detail. One of the most crucial aspects that often distinguishes a well-functioning laboratory from a potentially hazardous one is the incorporation of redundant systems. These systems ensure that critical safety measures remain operational even in the face of unexpected failures, thereby safeguarding both personnel and the research being conducted. Understanding Redundant Systems in Laboratory Design Redundant systems refer to the implementation of backup or secondary systems that can take over the function of a primary system if it fails. In high-containment laboratories, such as those classified as BSL-3 or ABSL-3, where work involves dangerous pathogens or hazardous materials, redundancy is not just a recommendation—it’s a necessity. These laboratories must adhere to safety guidelines set forth by the Centers for Disease Control (CDC) and the National Institutes of Health (NIH). For instance, in the design of HVAC (Heating, Ventilation, and Air Conditioning) systems within these labs, redundancy ensures that air filtration and directional flow are maintained even if one component fails. This is vital in preventing the escape of harmful agents into the environment. Similarly, redundant containment systems, such as double-walled isolation chambers or backup power supplies for critical systems, provide an additional layer of security. Case Study: University Client The recent project for a university to design a BSL-3 laboratory serves as a prime example of the importance of redundant systems. During the design phase, World BioHazTec emphasized the need for integrated redundant systems to ensure the lab’s safety and compliance with industry standards. By proactively identifying potential weaknesses in the design, such as HVAC failure scenarios, and addressing them through redundancy, the project team was able to avoid costly rectifications later in the construction and commissioning phases. Another key focus was implementing administrative controls alongside redundant engineering controls. This approach ensured that even if a primary control system failed, the secondary system would maintain safety protocols, thereby reducing the risk of containment breaches. Why Redundancy Matters The primary reason for incorporating redundant systems in high-containment labs is to protect human life and the environment. In these labs, where the stakes are incredibly high, a single failure can lead to catastrophic consequences. Redundant systems act as a safety net, ensuring that the lab remains secure even in the worst-case scenario. Moreover, redundancy in design also facilitates compliance with regulatory requirements. In the United States, agencies like the CDC require laboratories to demonstrate that they have adequate safety measures in place to handle any potential failures. By integrating redundant systems from the outset, labs can more easily meet these stringent requirements, ensuring a smoother commissioning process. Conclusion Redundant systems are not just an added feature in high-containment laboratories—they are a critical component of safe, reliable and sustainable design. As our university client project illustrates, the careful planning and implementation of these systems can make the difference between a safe, compliant laboratory and one that poses significant risks. For any organization involved in designing or operating high-containment labs, investing in redundancy is investing in safety, compliance, and the long-term success of their research endeavors.

To mitigate this risk, it’s essential to: Clean and Prime: Ensure that the substrate surface is thoroughly cleaned to remove any contaminants that might interfere with adhesion. Applying a primer that is compatible with both the substrate and the cladding material can significantly enhance adhesion. Control Moisture Content: High moisture levels in the substrate can compromise adhesive effectiveness. Specifying a maximum allowable moisture content for application can prevent detachment due to moisture-related issues. Application Techniques Proper application techniques are vital for ensuring secure attachment of the cladding material. Consider the following: Adhesive Application Guidelines: Provide detailed guidelines for applying adhesives and tapes, including recommended environmental conditions such as temperature and humidity. Clear instructions on curing times for adhesives will help minimize installation errors. Qualified Installers: Specify that the installation should be carried out by a contractor recommended by the manufacturer. Additionally, the installer should have experience with similar installations (World BioHazTec recommends more than 3) to ensure they are familiar with best practices. Substrate Compatibility Different substrates may require different approaches to ensure optimal adhesion. It’s important to: Evaluate Compatibility: Assess the compatibility of the cladding material with various substrates such as wallboard, concrete, and metal. Specify any necessary primers or adhesives to enhance adhesion based on the substrate type. Consideration of Environmental Forces Negative Pressure Gradients BSL-3 laboratories operate under negative pressure to prevent the escape of hazardous materials. This unique environment can exert significant forces on wall cladding: Calculate Maximum Force: Determine the maximum force exerted on the cladding due to negative pressure gradients. This should consider the largest potential pressure differential between the inside and outside of the laboratory. Apply a Safety Factor: Incorporate a safety factor to account for variations and uncertainties in pressure gradients. This ensures that the cladding material can withstand unexpected forces without detachment. Verification of Performance Reference Verification Ensuring that the cladding material has a proven track record in similar environments is essential: Request References: Require bidders to provide references of BSL-3 laboratories where their cladding materials have been successfully used. Include detailed contact information and installation dates. Verify Performance: Contact the provided references to verify the performance and durability of the cladding material in real-world BSL-3 environments. Seam Validation Seam integrity is crucial for maintaining the negative pressure environment in BSL-3 labs: Leak Testing: Specify the use of an air leak tester to validate the integrity of wall seams. This ensures there are no air leaks that could compromise the negative pressure environment. Warranty Given the critical nature of BSL-3 laboratories, a robust warranty is essential: Extended Warranty: A one-year warranty for materials is insufficient. Specify a warranty that covers both materials and workmanship for a minimum of ten years. This provides assurance that the cladding material will perform reliably over the long term. Conclusion By addressing these key considerations, you can enhance the reliability and performance of wall cladding in BSL-3 laboratories. Ensuring proper surface preparation, application techniques, substrate compatibility, and accounting for environmental forces are crucial steps.

Pressure Decay Testing and Why It is Important in BSL-4 Laboratory Annual Verification Testing

What is Pressure Decay Testing? Pressure decay testing is a systematic procedure to validate room construction to determine if the laboratory’s containment barrier defined by walls, floors, ceilings, penetrations, and other construction features meet the required integrity to prevent leakage of unfiltered air from the BSL-4 containment space. Pressure decay testing is the most reliable method to prove that a BSL-4 laboratory room’s envelope is airtight. The National Institutes of Health, which oversees the operation of the BSL-4 laboratories located in Fort Detrick, Maryland, and Hamilton, Montana, indicates that the standard BSL-4 pressure testing method is to negatively pressurize the room to 2 InH2O, and then measure the pressure decay. The requirement for a BSL-4 laboratory is to maintain a pressure higher than 1 InH2O after 20 minutes (Memarzadeh, 2009). This quantifiable test can pinpoint issues with critical equipment in a BSL-4 laboratory including: Air distribution valves Isolation dampers and actuators Isolation dampers bioseals APR doors gaskets Barrier autoclaves gaskets and seals Breathing air system lines Laboratory vents Why is Pressure Decay Testing Important? Pressure decay testing provides an acceptable level of quality for annual verification testing of BSL-3 Ag and BSL-4 laboratories. The complex design and operation of these facilities minimize the potential risk of an aerosolized pathogen to staff, the general population, and the surrounding environment. The pressure decay test verifies that there is no air leakage. Air leakage can compromise research studies through cross-contamination of multiple pathogens. How to Prepare for Pressure Decay Testing? The following steps must occur before conducting a pressure decay test: Verify the facility’s HVAC system is operational and commissioned. Verify the building automation system (BAS) is operational. Provisions for setting up testing equipment are available (pressure transducer enclosures, decontamination ports, etc.) Use either testing vacuum pump or exhaust system to negatively pressurize the system up to 2.00 InH2O. Check all potential sources of leakage for audible or identifiable leakage. To the extent practical, eliminate/minimize potential sources of heat generation so that the space stays at a relatively constant temperature throughout the testing (lights, freezers, motors, etc.) Isolate the affected areas from pressure fluctuations that will affect the testing. Monitor room Differential Pressures (DP) with static conditions (no airflow or pressurization air) to ensure that there are no external effects that will invalidate the results. All plumbing fixtures and floor drain traps are filled with water. If previously identified, all construction deficiencies have been rectified and completed. Ensure no visible damage is apparent to the room under test. All conduit, wiring, and electrical boxes have been epoxy-sealed. All epoxy coatings (if epoxy coatings are present) are in place and free of visible defects. Seamless flooring is in place and free of visible defects. Check valves and isolation valves are in place and operational. Dunk tanks (if installed) are filled. Autoclaves are operational and have their seal barriers in place. APR doors are functional and interface to BAS, and door access control systems are operational. Room temperatures are measured and data logged. Changes in temperature cause changes in pressure. Atmospheric pressure is measured using an instrument with an accuracy of 0.01 In. Hg. which is equivalent to 33.86 Pa or .136 InH2O. A pressure decay test form has been generated. It has been confirmed that room and general laboratory conditions are acceptable for testing the laboratory. The subject test area should be isolated and then allowed to stand for 20 minutes before commencing the test. Acceptance Criteria The room passes the pressure decay test if the residual pressure at the end of the 20-minute period is -1.00 InH2O or more negative (50% of the initial room’s pressure value) under steady state conditions for temperature and barometric pressure. Each pressure zone within maximum containment (BSL-4) must pass two consecutive pressure decay tests. If Pressure Decay Testing Is Not Feasible If annual pressure decay testing is not feasible for some rooms, then another option would be conducting a smoke saturation test. A smoke saturation test is a qualitative test, but it will help the users to identify possible issues with the containment envelope. The maximum containment engineering/maintenance team will need to command the laboratory into maintenance or decontamination mode. The surrounding areas will be more negative; therefore, if there is a leak or issue during the testing, the maximum containment team will be able to identify it. The challenge with this method is that it is only recommended if the rooms are decontaminated. Another option (a little bit messy and more time-consuming) is the use of a soap solution on critical areas. This test is the least accurate option because it will only test perimeter barrier components. The laboratory will require decontamination prior to testing. “Light Pressure Decay Test” If there is a decontamination or maintenance mode for the facility, you can run what we call a “light pressure decay test.” Before a decontamination process begins, you need to make sure the laboratory is airtight. The light pressure decay test is typically conducted from the BAS for testing and running trends. No additional testing equipment is used. This is a non-invasive procedure. What About BSL-3 Laboratories? BSL-3 laboratories can be pressure decay tested depending on the laboratory’s envelope construction system, calculated room’s leakage rate, and room’s isolation capabilities. Pressure decay testing on BSL-3 laboratories is more challenging since, by concept, these types of laboratories are considered “leaky labs” (infiltration of air is required). However, with the implementation of good room isolation standard operating procedures, the pressure decay test can be achieved with no issues. Recommendations Pressure decay testing is a team effort. Our recommendations to have a successful pressure decay test include: Make sure to get involved with experienced staff and a third-party consultant such as World BioHazTec from the beginning. Pressure decay testing is a critical testing procedure that requires experience and knowledge of BSL-4 and BSL-3 laboratories. Pressure decay testing should not be rushed. It requires coordination and is a team effort that involves the biosafety officer, Responsible Official, Alternate Responsible Official, facility director, facility personnel, and contractors. Differential pressure meters and test equipment calibration must be current and traceable to NIST. Check and double-check items which could inadvertently affect the testing outcome. If room or atmospheric conditions are not stable, such as a thunderstorm, do not hesitate to reschedule the test.
