    Researchers perform all experiments in a biosafety cabinet.
    BSL-3 laboratories are designed to be easily decontaminated..

  • What is the principle of biosafety levels?

    BSL-1 is designated for those working with microbes that don't cause disease in healthy humans, for example, non-pathogenic E. coli.
    BSL-2 is for labs that work with pathogens including organisms such as Staphylococcus aureus or Vibrio cholerae..

  • Who works in a BSL 4 lab?

    Working in the BSL-4-Laboratory
    Up to ten scientists and technicians can work in the cell culture laboratory simultaneously.
    They prepare virus samples at laboratory work benches – high-risk work needs to be overseen by another person..

4 Biosafety Lab Levels
  • BSL1. Controlled access. Hand washing sink. Sharp hazards warning policy.
  • BSL2. Controlled access. Hand washing sink. Sharp hazards warning policy.
  • BSL3 (with risk-based enhancements) Air tight when disinfecting. Self-closing, double-door access.
  • BSL4. Air tight. Self-closing, double-door access.
Biosafety levels (BSL) are used to identify the protective measures needed in a laboratory setting to protect workers, the environment, and the public.
