What is the difference between BSL 2 and BSL 3?
This is provided to demonstrate that BSL-2 is largely achieved through sound lab safety practices and BSL-3 is achieved through the addition of facility features and equipment designed for containment of aerosols to a foundation of sound lab safety practices..
What does BSL 3 mean?
Biosafety level 3 (BSL-3) is applicable to clinical, diagnostic, teaching, research, or production facilities where work is performed with agents that may cause serious or potentially lethal disease through inhalation, to the personnel, and may contaminate the environment.
How many BSL levels are there?
There are currently four levels of biosafety for laboratories [15, 16, 17, 18, 19]. The first level is for agents that do not pose a significant threat to human health. Level two is intended for those that present a low to moderate risk. Level three is where potentially lethal pathogens are handled.
What is the difference between BSL 1 and BSL 2?
BSL-2 laboratories maintain the same standard microbial practices as BSL-1 labs, but also includes enhanced measures due to the potential risk of the aforementioned microbes.
What are Level 4 viruses?
Biohazard Level 4 usually includes dangerous viruses like Ebola, Marburg virus, Lassa fever, Bolivian hemorrhagic fever, and many other hemorrhagic viruses found in the tropics.
What is a BSL 2?
BSL-2 laboratories are used to study moderate-risk infectious agents or toxins that pose a moderate danger if accidentally inhaled, swallowed, or exposed to the skin. Design requirements for BSL-2 laboratories include hand washing sinks, eye washing stations, and doors that close and lock automatically.
