What are the differences between biosafety level 1 and biosafety level 2 facilities in terms of their containment measures and safety protocols?

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.
