Biosafety Level (BSL) labs

Biosafety Level (BSL) labs are specialized facilities designed to safely handle infectious agents, with levels 1 through 4 indicating increasing precautions. BSL-1 labs manage non-harmful organisms, requiring minimal safety measures. BSL-2 labs handle moderate-risk microbes, involving protective gear and restricted access. BSL-3 labs work with dangerous pathogens that can cause serious illness, with stringent controls like sealed rooms and specialized ventilation. BSL-4 labs are for the most dangerous viruses, requiring full-body suits, advanced containment, and airtight environments. These levels ensure researcher safety and prevent pathogen release into the environment.
