biosafety level facilities

Biosafety level (BSL) facilities are specially designed laboratories that handle different types of biological agents, from harmless to highly dangerous. They are classified from Level 1 to Level 4, with Level 1 being the safest and Level 4 used for extremely deadly pathogens. Each level has specific safety practices, equipment, and containment measures to protect workers and prevent the spread of harmful microorganisms. The higher the level, the stricter the safety standards, such as sealed rooms, specialized ventilation, and protective gear, ensuring safe handling of dangerous biological materials.
