BSL-4 (Biosafety Level 4)

Biosafety Level 4 (BSL-4) is the highest level of containment used in laboratories handling the most dangerous infectious diseases, such as Ebola or Marburg viruses. These labs feature advanced safety measures, including fully sealed environments, specialized ventilation systems, and protective suits for staff, to prevent any release of deadly pathogens into the environment. BSL-4 labs are designed to conduct research safely on extremely hazardous agents that pose a high risk of severe illness or death, ensuring that scientists can study these pathogens while protecting public health and the environment.
