A BSC should be utilized in procedures involving open vessels of biohazards that:

Using a Biological Safety Cabinet (BSC) is essential for various procedures involving open vessels containing biohazards, particularly when certain risk factors are present. In cases where procedures may produce infectious aerosols that cannot be contained by other means, a BSC provides a crucial layer of protection for the individual and the environment. The design of a BSC helps to capture and filter these aerosols, minimizing the risk of exposure.

Additionally, when dealing with high concentrations or large volumes of biohazards, the potential risk to laboratory personnel increases. A BSC is engineered to create a sterile environment and offers continuous airflow that serves to protect both the samples being handled and the operator from exposure to potentially harmful pathogens.

By addressing scenarios that encompass the risk of aerosol generation, high concentrations, and large volumes of biohazards, the use of a BSC becomes not just a safety measure, but a requirement in settings where such risks are present. This comprehensive approach to safety underscores the importance of utilizing a BSC in all these critical circumstances.
