How to Perform a Risk Assessment and Choose a Biosafety Cabinet

Julianne L. Baron, Ph.D., CPH, RBP
Dr. Lora Grainger

Choosing the right biosafety cabinet (BSC) is a critical decision for any laboratory handling biological materials. This on-demand educational webinar, led by Dr. Laura Grainger of Project SafeLab and Dr. Julianne Baron of Science and Safety Consulting, walks through the full lifecycle of risk assessment and cabinet selection—from hazard identification to final installation and use.

Whether you are setting up a new lab or upgrading existing containment systems, this presentation provides the expert insight you need to make confident, compliant, and scientifically sound choices.

Why Risk Assessment is Essential

Before selecting a biosafety cabinet, a biological risk assessment must be conducted to evaluate the hazards posed by your materials, procedures, and lab environment. This includes considering:

Infectivity of the agent
Mode of transmission (especially aerosol generation)
Volume and concentration
Equipment used inside the cabinet
Potential consequences of exposure or contamination

The webinar explores a framework for risk assessment as a control strategy, using the principles of assessment, mitigation, and performance. For a more in-depth overview of risk-based cabinet selection, visit our white paper on BSC selection and risk assessment.

Understanding Biosafety Cabinet Classes and Types

Dr. Grainger and Dr. Baron explain the different classes of BSCs (I, II A1/A2, B1, B2, C1, and III), including:

Airflow patterns and HEPA filtration
Recirculation vs. total exhaust
Compatibility with volatile chemicals
User, product, and environmental protection

They also clarify when to use each type based on your lab’s biosafety level (BSL-1 to BSL-4) and whether chemical use is part of your workflow.

Customization and Workflow Optimization

In today’s complex research environments, BSCs are rarely one-size-fits-all. This webinar emphasizes the importance of workflow analysis and ergonomic design to ensure safety, efficiency, and comfort.

From Planning to Installation

Beyond cabinet selection, successful implementation requires proper facility planning and installation. The speakers highlight how cabinet placement, airflow interference, and ductwork influence safety and certification.

For comprehensive planning guidance, explore:

SOPs, HEPA Maintenance, and Long-Term Safety

Even the best cabinet cannot guarantee safety without proper use and maintenance. This session addresses:

Understanding HEPA filter function and when to test or replace
Importance of airflow and alarm systems
Developing and enforcing Standard Operating Procedures (SOPs)
