In a scenario where there is a risk of aerosol production, employing a Level 2 biosafety cabinet is essential. This type of cabinet is specifically designed to provide adequate levels of safeguarding for laboratory professionals and the surrounding environment when working with biological materials that pose a moderate risk to health.

Level 2 biosafety cabinets offer protection through a combination of physical barriers and air filtration. They utilize high-efficiency particulate air (HEPA) filters to trap potentially infectious aerosols as they are created, thus minimizing exposure and preventing the spread of contaminants. The cabinet's design ensures that air is constantly drawn into the work area and then filtered before being recirculated, thereby maintaining a safe working environment.

While the Level 1 biosafety cabinet does provide some protective measures, it is insufficient for handling materials that pose higher risks. Level 3 biosafety cabinets are used for even higher-risk pathogens requiring more stringent containment measures, which is unnecessary in the context of Level 2 risks. Laminar flow hoods primarily provide protection for the products being worked on rather than for the personnel or environment, making them unsuitable for scenarios where aerosol risks are present. Thus, a Level 2 biosafety cabinet is the correct choice in this situation to ensure the required containment and safety
