biosafety level 2
Noun: A containment level for laboratory work involving agents of moderate potential hazard to personnel and the environment. It is suitable for work with indigenous, moderate-risk agents that are present in the community and associated with human disease of varying severity, but which are not typically transmitted via airborne routes and for which effective treatments and preventive measures are often available.
This term is used in scientific, medical, and regulatory contexts to classify and describe the specific protocols, laboratory design, safety equipment, and work practices required when handling certain biological materials. - The research on these bacteria must be conducted at biosafety level 2. - All personnel working in a biosafety level 2 lab must receive specific training.
- The virus sample was downgraded to biosafety level 2 after further review determined its transmission risk was low.
- Standard microbiological practices, along with specific protective equipment and lab design features, define a biosafety level 2 facility.
- This protocol requires a biosafety level 2 environment because the pathogen can cause acute disease via accidental ingestion or skin puncture.
- "to work under/at biosafety level 2": To perform laboratory procedures in a facility operating under BSL-2 containment conditions.
- The clinical isolates are handled under biosafety level 2 containment.
- BSL-2: The common abbreviated form of "biosafety level 2".
- The new lab is certified for BSL-2 work.
- Biosafety Level (BSL): The general classification system with four primary levels (BSL-1, BSL-2, BSL-3, BSL-4).
- Containment Level: A synonymous term often used interchangeably with biosafety level.
- Containment Level 2
- Moderate Risk Containment
- BSL-2 Practices: The specific standard and special practices mandated for this containment level, such as the use of biological safety cabinets for aerosol-generating procedures.
- BSL-2 Facility: A laboratory designed with specific features (e.g., self-closing doors, handwashing sinks, eyewash stations) to meet the requirements for this level of containment.
-
exposure to infectious agents that can cause disease in humans but whose potential for transmission is limited
