Study Notes
Biosafety and Biosecurity
- The primary purpose of biosafety barriers in a laboratory is to prevent the exposure of laboratory workers, the environment, and the community to biological agents that may cause infection or other adverse effects.
Biosecurity
- Biosecurity primarily aims to prevent the theft, diversion, or intentional misuse of biological agents or toxins that could be used as bioterrorism agents.
Biorisk
- Biorisk encompasses both biosafety (risks to humans and the environment) and biosecurity (risks of intentional misuse) aspects of biological agents.
Personnel as Biosafety Barriers
- Personnel play a critical role as a biosafety barrier by following laboratory protocols, wearing personal protective equipment (PPE), and adhering to standard operating procedures to prevent exposure to biological agents.
Laboratory Biosafety Levels (BSL)
- Laboratory biosafety levels (BSL) standards primarily address the physical containment and safety requirements for working with biological agents, ranging from BSL-1 (lowest risk) to BSL-4 (highest risk).
