Evaluating side-by-side placement of class II biosafety cabinets

In this white paper, NuAire presents evidence-based guidance for laboratory professionals, facility designers, and biosafety officers on optimal biological safety cabinet (BSC) positioning. Authored by industry experts Bill Peters, Dan Hillman, and Ron Trower, the paper explores how environmental variables—including HVAC systems, airflow patterns, and personnel movement—can influence containment performance at the cabinet’s critical work access opening.

Through rigorous testing, including bacterial aerosol challenge studies, the white paper evaluates the impact of placing BSCs side by side or in close proximity. It references key standards such as NSF/ANSI 49 and the CDC/NIH Biosafety in Microbiological and Biomedical Laboratories (BMBL) guidelines to support its findings.

Among the core recommendations is the establishment of adequate clearance between adjacent cabinets to preserve airflow integrity and containment reliability. The paper also underscores the importance of accounting for laboratory layout, room air velocities, and staff traffic patterns when planning BSC placement.

This resource offers practical, scientifically validated strategies to help ensure that BSCs perform to their intended safety specifications—contributing to a safer and more efficient laboratory environment.

Access the white paper to optimize your BSC installation strategy and uphold the highest biosafety standards.

Best practices for positioning a class II, type A2 biosafety cabinet

This expert-designed infographic provides essential guidance for scientists, laboratory managers, and pharmacy professionals on the correct placement of Class II, Type A2 biosafety cabinets (BSCs) within laboratory or cleanroom environments. It outlines how improper positioning—particularly near disruptive air currents—can compromise airflow integrity, increasing the risk of contamination.

The infographic details how high-velocity cross-drafts may interfere with the cabinet’s inflow and exhaust dynamics, especially at the vulnerable exhaust HEPA filter area. Such disturbances can overwhelm the cabinet’s protective air barrier, reducing operational safety and compromising sample integrity.

Additionally, the resource addresses critical exhaust considerations for cabinets used in procedures involving trace amounts of radionuclides or small quantities of non-flammable, non-explosive, volatile, toxic chemicals. Guidance is provided on the role of properly functioning canopy exhaust systems in maintaining compliance and ensuring safe handling.

Case StudyGeneral Lab

Utilizing custom solutions for robotics & automation

In this whitepaper, NuAire discusses its custom airflow solutions for robotics and automation in the pharmaceutical industry. The paper highlights a specific case study with the French pharmaceutical company Sanofi, which partnered with NuAire to develop custom class II biosafety cabinets to accommodate the increasing need for automation and oversized equipment in its labs. NuAire's expertise in custom design helped Sanofi overcome standard biosafety cabinets' limitations and safely interact with samples in a large-scale format. The paper also describes the custom design process, which begins with an in-depth interview and progresses through an iterative exchange of engineering drawings and models.

Facility and Engineering Controls Using USP 800 Guidelines

Like many layers of an onion, there are unanswered questions on the intricate details of USP 800-related engineering control parameters. In addition, the multitude and flexibility of theengineering controls can seem daunting to the independent pharmacy owner. Even more concerning, and certainly at the forefront of all of the independent pharmacy owners’ minds, is the cost associated with being compliant with USP 800. The costs associated with building a new facility or remodeling an existing space, are proving to be as equally subjective as the choice of engineering controls. The focus of this white paper is to discuss the details for consideration of a good working design of a USP 800 compliant compounding lab.

How to Perform a Hazardous Drug Risk Assessment in the Compounding Pharmacy

There is a looming deadline on December 1, 2019 and that is the implementation of USP chapter <800>-Hazardous Drugs, Handling in Healthcare Settings. State Boards of Pharmacy (SBOP) are forming task forces and committees to determine if their state will fully implement the chapter or if they will only implement certain components of the chapters. And yet there are other states that are unsure what to do and may push the enforcement further down the timeline. Regardless of what your SBOP has determined regarding USP <800> enforcement, it is still wise to examine the risks associated with hazardous drug chemical handling in your entity. Mitigating risk may not be at the forefront of your mindset, but like the USP <800> deadline, the issue of chemical exposure risk is looming in all healthcare facilities that handle hazardous drugs (HDs).
