In biosafety, what does the term 'containment' specifically refer to?

Containment in the context of biosafety specifically refers to the practices, procedures, and physical barriers designed to limit exposure to biohazards. This includes strategies to prevent the release of potentially harmful biological agents into the environment, as well as measures intended to protect laboratory personnel and the general public from exposure to these agents. Effective containment is crucial for maintaining a safe working environment in laboratories that handle infectious materials, ensuring that any biohazards are kept secure and that any risk of exposure is minimized.

The other options relate to aspects of laboratory safety or operational procedures but do not encapsulate the specific meaning of containment. Managing laboratory supplies, neutralizing pathogens, and emergency procedures are important elements of biosafety but are not the definition of containment itself.
