Looking for a BSL-2 Laboratory Space?
January 31, 2023
Five things to consider when scoping out a BSL-2 lab space to keep your workers safe.
More and more commercial building landlords set aside laboratory space to lease. When scoping out possible options for existing laboratory space, beyond the research experiment, you need to consider worker safety. Being risk averse is a good practice when walking through potential laboratory spaces for your next research project. Here are 5 things to consider when scoping out a BSL-2 laboratory.
1. Establish Your Criteria Through Safety Guidelines
Safety in a laboratory is paramount! There are guidelines available to you that can serve as your criteria or provide a checklist to ensure that when evaluating a space, it “checks the boxes.” When looking for a new home, most people have their “dealbreakers” (e.g., must have 3 bedrooms and a walk-in pantry) versus their “bonuses” (e.g., pool and wood-burning fireplace). The same idea can be applied when looking at a potential BSL-2 laboratory space. What are your dealbreakers?
Establishing your safety guidelines before you even call a landlord to inquire about a space is a good way to communicate what kind of laboratory space is needed. The Biosafety in Microbiological and Biomedical Laboratories (BMBL) published by the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) provides guidance on the laboratory space requirements. The World Health Organization (WHO)’s Laboratory Biosafety Manual is another source that will guide you how to approach your laboratory with a balanced risk assessment.
Please be informed, the BMBL is a guideline and not a regulation. If a laboratory space does not meet all of the statements within the guidelines, you can conduct a risk assessment to evaluate the potential risk and impact to your research, workers and the surrounding environment. A workaround solution such as an administrative control can provide an easy resolution. Workaround administrative control solutions will require training and monitoring so factor that into your decision-making.
Preplanning will expedite decision-making and protect your most valuable personnel as well as the tenants who share the building. If you are an employer or landlord and in need of a space evaluation, risk assessment or a second opinion if whether a space or building qualifies for a biological containment laboratory, contact us for more information.
2. Adequate Inward Directional Airflow
Inward directional airflow that does not recirculate outside of the BSL-2 laboratory is highly recommended by the BMBL to ensure that sufficient air is being drawn into the BSL-2 laboratory and to prevent aerosol transmission from the laboratory into another part of the building. Inward directional airflow draws air into the laboratory from the “clean” areas (e.g., corridor outside of a laboratory) and toward “potentially contaminated” areas (e.g., a biological safety cabinet [BSC]). Although not a requirement, the BMBL and WHO Laboratory Biosafety Manual recommends that a BSL-2 laboratory has inward directional airflow. The rationale is to eliminate the risk of others in the building from being exposed to the biological and/or chemical materials that could be released into the space inadvertently.
Verification of directional airflow can be accomplished and documented by a Testing and Air Balance (TAB) Report or by an engineer’s testing and certification. A pressure differential target value is at least .05 In. H2O (15 Pascals) which approximates 100 CFM passing through the crack area of the entry door. Ask the landlord for a TAB Report so you can verify if there is directional airflow. Not sure where to start or how to read a TAB Report? Contact us and we can help you.
3. Biological Safety Cabinet (BSC) Placement
The BSC is a key area where your manipulations will occur in the BSL-2 laboratory. When walking through the laboratory, consider where the BSC will be placed. You want to make sure that people walking by do not disrupt the air inflow into the BSC. Rule of thumb is to place the BSC away from doors and common pathways within the laboratory. If you have limited options, put a demarcation line on the floor (red tape works well) as a visual aid as to where not to walk. Train and periodically observe your laboratory personnel to ensure they do not cross the demarcation line when walking past the BSC.
Ideally, the BSC should be placed as far as possible from the entryway. The objective of directional airflow is to draw air from the “clean” areas toward the potentially contaminated areas. The BSC is the most potentially contaminated space within the laboratory. Having your BSC placed far from the entryway reduces the risk of exposure and minimizes BSC airflow disruption.
One last point about BSCs and their required annual testing. There needs to be at least 12 inches between the HEPA filter of a Class II type A2 BSC for scanning the HEPA filter. Make sure to check floor-to-ceiling clearance for the height of the BSC you will be using. Although BSC stands are adjustable, you do not want to have the BSC so low that it impacts the worker’s ergonomics. BSC heights are generally about 8 feet so you will need at least a floor-to-ceiling height of 9 feet.
4. Look Down At The Floor
Slips, trips, falls and spills are always a great risk in the workplace. The BSL-2 laboratory floor should be smooth, slip-resistant flooring. Sealed flooring is recommended. Watch out for manufactured floors with grooves or grouted floors that cannot be easily cleaned. We suggest verifying that the flooring material is chemical resistant and antimicrobial. Carpets and rugs are unacceptable.
5. Let This Sink In
You would be surprised how many times our experts evaluated laboratories that do not have sinks at the entry/exit ways. Good laboratory practice is to wash your hands before leaving the laboratory to minimize potential contamination of door hardware. Ideally, the sink should be located close to the laboratory exit so that after doffing PPE, the worker can wash their hands.
6. It Doesn’t Hurt To Ask
Surprise! We have a 6th tip. Discuss with the landlord and document what needs to be installed, repaired, or replaced before you take occupancy. Any annual maintenance items should also be discussed (e.g., filter changes, lighting relamping, etc.) and discuss deliveries to the facility (e.g., laboratory samples, bottled gasses, etc.). This effort will pay off in the future with you being a long-term tenant and establishing an amicable tenant and landlord relationship.

Outsourcing Training for Work in Critical Environments
When managing a high-containment facility, such as a BSL-3 lab, safety is paramount. Training staff to handle biological hazards properly and operate within stringent protocols can literally be a matter of life and death. A critical question many organizations face is whether to develop training programs in-house or outsource this training to a specialized provider. We’ll explore barriers to in-house development and delivery of quality training and why outsourcing your training for high-consequence workplaces could be the best option for your organization. What are your barriers to faster learning design and development? A recent survey conducted by the Association for Talent Development (ATD), which has supported instructional developers of employee training programs worldwide for over 80 years, identified eight top barriers to faster learning design and development.[1] The top three barriers are: Adapted from DeFelice, R. 2021. ATD Blog. Rounding out the top eight barriers include lack of availability of Subject Matter Experts (SMEs) or stakeholders at 37%. In our experience, SMEs and stakeholders have many hats they wear, and their time is limited. Often, SMEs are outside of the organization and pose an additional expense to the development of in-house training, initially and annual updates to the curriculum. World BioHazTec uses the Successive Approximation Model (SAM) approach to instructional design. SAM is a three-phase process: Preparation Phase, Iterative Design Phase, and Iterative Development Phase.[2] SMEs and stakeholders are brought in at the initial outlining phase and then only as needed for review. Because this is an iterative process, by the time the final phase is reached, SMEs and stakeholders have agreed to the plans and there should be very few revisions, or scope creep, to the design and plans. This saves time for these busy professionals and reduces costs by managing time and scope. Limited learning infrastructure—such as access to dedicated systems, authoring tools, and networks—accounts for 35% of the barriers. Authoring tools and resources, such as licensed images, add to the expense. Additionally, online self-paced (asynchronous) learning modules require authoring tools to create interactive content with feedback, as well as a learning management system to deliver the modules effectively. The final three barriers are a lack of learning and development skills within the talent development team (25%), lack of accountability (when the talent development team or SMEs do not fulfill responsibilities or meet deadlines) (23%), and insufficient leadership or management support (19%). These barriers indicate that staff are often occupied with other duties, with training development frequently becoming a lower priority. How much extra time does your staff have? Developing in-house training programs takes time—far more than many organizations realize. According to ATD in its most recent survey, creating one hour of new classroom training can take anywhere from 112 to 367 hours to develop.[3] That means developing just a half-day session could consume weeks of work by several employees. Time that could be better spent on other critical functions of your lab. Also, think of the breadth of knowledge and skills required to operate and maintain a high-containment laboratory, both for inside and outside, from construction to cybersecurity, from environmental protection to personal safety. Biosafety professionals not only require training in performing their jobs safely, they are also involved in risk assessments and compliance with applicable regulations daily, and appropriate emergency response. Frequently, the biosafety professional is called upon to participate in the planning, design, and validation of a new biocontainment laboratory or renovation of an existing facility. “Biosafety professionals should have a foundation in all aspects of working in and around a high-containment laboratory and develop skills to ask questions in specific terms and have the confidence to question the answers.” -World BioHazTec Course Development Guide. [Internal Communication] Developing meaningful, high-quality training that addresses all necessary components typically requires more SMEs and stakeholders than a single facility may have available for training development. Outsourcing training development strengthens course quality by bringing together SMEs with various expertise for only the time that is necessary under the management of a proven training development team. Also, the development team can use resources already developed to tailor to the specific needs of your facility and staff, which saves time and resources. If you’re thinking of transitioning your existing training into an online format, the time investment can be even greater. Converting a course into effective web-based training requires expertise in instructional design, an investment in e-learning tools, an understanding of e-learning platforms, and the ability to ensure that virtual training still delivers the same level of engagement and effectiveness as in-person sessions. Just as with any training, online training and learning management systems must be monitored regularly and reports generated to stakeholders. Outsourcing this process to specialists not only saves your team countless hours but also ensures the training is designed by professionals with experience in biosafety, biosecurity, and online learning. A Fresh Perspective and Unbiased Assessment One of the key benefits of outsourcing your BSL-3 training is gaining access to an external team of experts who can offer a fresh perspective. When organizations develop their own training programs, there’s often a risk of becoming too close to the material, potentially missing gaps or risks that an SME might spot, offering a fresh perspective. An external provider can objectively assess your current protocols, highlight potential areas for improvement, and suggest best practices based on up-to-date industry standards. “Things change quickly …, so job responsibilities must evolve. If companies evolve their strategy and expect employees to expand their skill sets, offering a team continuous learning will help prevent them from falling behind.” [2] In high-stakes environments like BSL-3 labs, where even minor oversights can have serious consequences, having an unbiased third-party review can add an additional layer of safety. Expert consultants are experienced in tailoring their training programs to meet both your specific operational needs and strict regulatory requirements, ensuring your staff is fully equipped to handle emergencies and day-to-day challenges. CEUs and Professional Development Incentives Professional development is also a tool for employee retention. “About 80 percent of employees rank professional development and continuous learning as high priorities when job hunting. And 94 percent of employees say if an employer invested more in learning and development, they would stay longer at an organization.” [3] Another significant advantage of outsourcing BSL-3 training is the ability to offer Continuing Education Units (CEUs). If your training provider is accredited, they can award CEUs to participants which can be used to maintain certification with professional organizations. This ensures your team remains compliant with the latest industry developments and ongoing certification requirements. It also provides an added incentive for staff to engage in the training. CEUs enhance the perceived value of the training, as they provide tangible career benefits to employees. By outsourcing, you can integrate this offering into your program without the burden of navigating the lengthy accreditation process yourself. Outsourcing Offers Expertise, Efficiency, and Compliance The decision to outsource BSL-3 training boils down to efficiency and safety. By partnering with an experienced external provider, you’re investing in expert insights, saving substantial time, and ensuring your team has access to accredited, top-tier training. Not only does this free up your internal resources, but it also offers peace of mind knowing your staff is receiving the most current and comprehensive training available.

Five Design Considerations for Animal Laboratories
At the beginning of the design process, there are many decisions that must be made regarding equipment, sinks, showers, biological safety cabinets (BSCs), and other primary barrier equipment, the configuration of the HVAC system, and contingencies based upon the facility design elements required by the agents that will be worked with or studied. Sustainability, maintainability, and energy usage must also be factored into the design. Organizational preferred operations must be included, and SOPs often dictate final designs. Spatial relationships need to be evaluated to determine flow and function. When animals are part of the laboratory work, additional design features are needed which add complexity to the design. 1. Design Standards, Guidelines, and Regulations for Animal Laboratories Paramount to safety is the understanding of the application and intent of biosafety and biocontainment guidelines. Biosafety design is based upon risk assessment. The design team should be accustomed to working with the Biosafety Officer, users, and stakeholders in formulating and documenting risk assessments when needed to support design decision-making. Determining your research goals or planned laboratory work, grant design requirements, and regulatory compliance will drive the design criteria. When designing an animal facility such as an ABSL-2 or ABSL-3 laboratory, beyond the compulsory local national and international guidance documents, you may want to also consider the following guidelines and standards: NIH Design Requirements Manual for Biocontainment Laboratories; U.S. Department of Agriculture (USDA) Research Service Guidelines, (as applicable); Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC); National Research Council Guide for the Care and Use of Laboratory Animals; National Research Council Occupational Health and Safety in the Care and Use of Research Animals; and National Research Council Occupational Health and Safety in the Care and Use of Nonhuman Primates. 2. Odor The management of odor from animal facilities, autoclaving, waste treatment, and tissue digesters is unique to containment facilities. Elevator shafts and loading docks serve as pathways for the distribution of odors. Using positive pressured elevator vestibules, adjoining positive pressured corridors, and local ventilation can contain odors. Dedicating an elevator for vertical movement of animals from receiving to the animal suite will also control odors. Adding a pneumatic waste removal system can contain waste removal odors from the animal suite to the building loading dock area. These engineering controls allow for the placement of vivariums anywhere vertically in a research tower instead of the traditional basement location. 3. Noise Subjecting animals to noise and vibration can have significant impact on animal reproduction and sensory development, behavior, and can expose animals to injury startle responses. The location of rotating machinery in animal facilities can stress animals, so cage washing areas and mechanical spaces with fans and pumps need to be distanced from animal holding areas. Another source of noise is the ventilation system with elevated room level supply and exhaust noise. In addition to negatively affecting animals, this can also affect workers’ communication and awareness to their surroundings. 4. Space Requirements Caging design, rack sizes and types, and animal model are key factors in analyzing space requirements. Identifying the maximum number of types of animals to be housed according to biosafety level can maximize space utilization for the present and the future. This information bears heavily on the design approach to room space allocation, cage washing equipment, whether disposable caging is more economical, cage changing stations or BSCs, and watering system versus bottle caging. 5. Emergency Signaling Systems Placement of emergency signaling systems (e.g., fire alarm, HVAC failure alarm, room pressurization alarm, security alarm) is essential to alert personnel to act. Signaling systems must be accessible for lab personnel, biosafety officers, and emergency response personnel. Ever conscious of animals, the alarms cannot be strobing in holding facilities so as not to stress animals. Animal Laboratory Design Recommendations In analyzing the final design, emphasis needs to be placed on the details. Constant referral to the research program requirements, containment guidelines, lessons learned, project construction and operating budgets, and the completeness of the design documents are essential to a successful design that meets the users’ and the stakeholders’ needs and provides sustainability. Efforts spent in design by an integrated team of users, professionals, and stakeholders will culminate in a safe, sustainable, efficient, and secure research facility.
