What are biosafety cabinets used for?

Biosafety cabinets are essential pieces of laboratory equipment specifically designed to provide a safe environment for handling biological materials that may contain pathogens or other hazardous substances. They create an environment that protects the user, the laboratory, and the surrounding community from exposure to potentially infectious materials, such as blood or other bodily fluids.

These cabinets use airflow and filtration systems to minimize the risk of contaminating both the samples being handled and the atmosphere in the lab. By working within a biosafety cabinet, personnel can conduct experiments or tests safely, while ensuring that there is no direct exposure to hazardous substances.

The other options do not pertain to the primary function of biosafety cabinets. They are not designed for storing personal protective equipment, conducting employee training, or providing space for office supplies. Hence, the correct answer accurately represents the biosafety cabinet's primary purpose in managing bloodborne pathogens and related risks.
