There are four biosafety levels (BSL) that range from BSL-1 (basic level) to BSL-4 (high level). BSL-1 involves basic safety practices, while BSL-2 requires additional precautions for moderate-risk agents. BSL-3 includes strict containment measures for pathogens that can cause serious diseases, and BSL-4 is for handling dangerous pathogens with no vaccines or treatments, requiring maximum containment.

A nested list is a list that contains several levels of items, with each level displaying a different numeric, alphabetic, or bullet symbol. The different levels of items are typically indented to show hierarchy and organization.

Biosafety level 1 facilities are basic labs that handle low-risk agents, with minimal containment measures and safety protocols. Biosafety level 2 facilities handle moderate-risk agents and have stricter containment measures, such as limited access and protective equipment, to prevent contamination and ensure safety.

How to do laboratory risk assessment in biosafety level
The highest level of biosafety studied at the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) is Biosafety Level 4 (BSL-4). This level is designated for working with highly dangerous and exotic pathogens that pose a high risk of aerosol transmission and for which there are no available vaccines or treatments. Facilities operating at BSL-4 require stringent safety measures, including specialized equipment and protocols to prevent exposure to infectious agents.
European BioSafety Association was created in 1996.
Biosafety levels 2, 3, and 4 require the placement of a biohazard sign on the door of the laboratory. This signage is essential to inform personnel and visitors about the potential risks associated with the pathogens handled within these facilities. The sign typically indicates the specific biosafety level and outlines necessary precautions. Level 1 labs do not require such signage as they deal with minimal risk agents.
biosecurity is limiting people's access to the agent. biosafety is limiting the agent's access to people.
Biosafety Level 4 (BSL-4) is the highest level of biocontainment used in laboratories and is unique for its strict protocols to handle highly dangerous and exotic pathogens that can cause severe or fatal diseases in humans, often with no available treatments or vaccines. BSL-4 labs require specialized facilities, including sealed environments, airlocks, and full-body, air-supplied suits for personnel. The stringent safety measures are designed to prevent any potential release of these pathogens into the environment. This level of biosafety is typically reserved for research involving agents like the Ebola virus and Marburg virus.
To obtain a BSL2 certification, individuals typically need to complete specific training on working in a Biosafety Level 2 laboratory, demonstrate understanding of safety protocols, and follow proper procedures for handling potentially infectious materials. Additionally, they may need to pass an exam or assessment to demonstrate their knowledge and competency in working at this biosafety level.
