What is the objective of using a Biological Safety Cabinet?

The primary objective of using a Biological Safety Cabinet (BSC) is to protect the user, the laboratory environment, and the surrounding community from exposure to biological hazards, including infectious agents and potentially harmful microorganisms. BSCs are specifically designed to provide a barrier between the user and the biological material being handled. They employ a combination of HEPA filtration and positive or negative airflow to ensure that airborne contaminants do not escape into the laboratory environment.

While maintaining a sterile environment, enhancing disinfection measures, and safely storing hazardous materials are important aspects of laboratory safety and protocols, they do not encapsulate the primary function of a Biological Safety Cabinet. The essential purpose is centered around containment and protection, making option B the most accurate statement regarding the use of BSCs. Such cabinets are a critical component of biosafety practices, especially in laboratories that handle pathogens or other biological materials that pose a risk to human health or the environment.
