A biosafety level (BSL), or pathogen/protection level, is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4).
Routine diagnostic work with clinical specimens can be done safely at Biosafety Level 2, using Biosafety Level 2 practices and procedures. Research work (including co-cultivation, virus replication studies, or manipulations involving concentrated virus) can be done in a BSL-2 (P2) facility, using BSL-3 practices and procedures.
This list of laboratory biosecurity incidents includes accidental laboratory-acquired infections and laboratory releases of lethal pathogens, containment failures in or during transport of lethal pathogens, and incidents of exposure of lethal pathogens to laboratory personnel, improper disposal of contaminated waste, and/or the escape of laboratory animals.
Biosafety level designations are based on a composite of the design features, construction, containment facilities, equipment, practices and operational procedures required for working with agents from the various risk groups. [10]
A "biosafety level" (BSL) is the level of the biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4).
In fact, all facilities in the United States of America that produce liquid waste of Biosafety Level 2 and above must decontaminate their waste before discharging it into a public sewer system. [2] Examples of liquids sterilised in an EDS include the shower water from personnel decontamination rooms, and the waste water from washing down animal ...

The vast majority (87.7%) of NML's lab space is Containment Level 2 (CL2). This is the same type of laboratory found in doctors' offices, hospitals and universities. In a Level 2 lab, work with infectious materials is done inside a biosafety cabinet (BSC) and appropriate personal protective gear is worn relative to activities (gloves, eye ...
