In a situation where there is risk of aerosol production, Level 2 containment requires a minimum of:

In the context of biosafety and laboratory containment, it is important to understand the specifications and purpose of different levels of containment. Level 2 containment is designed to handle pathogens that pose a moderate risk to personnel and the environment.

In situations where there is a risk of aerosol production, a Level 2 biosafety cabinet is specifically required. This type of cabinet provides personnel protection and a controlled environment to contain potentially hazardous materials, thus reducing the risk of exposure or contamination, which is crucial during procedures that could create aerosols.

While a Level 1 biosafety cabinet may offer some level of protection, it does not meet the necessary specifications for handling agents that can be transmitted via aerosols. Similarly, Level 3 biosafety cabinets are designed for higher-risk pathogens and would be excessive for moderate-risk situations. A laminar flow hood is primarily used for clean, non-hazardous work and does not provide the appropriate containment for pathogenic work.

Therefore, for procedures involving the risk of aerosol production, a minimum of a Level 2 biosafety cabinet is required to ensure adequate protection and containment.
