Biolevel Comparison

The following table summarizes the CDC/NIH recommendations concerning personnel practices for Biosafety Levels 1-3. 

Level 4 has been omitted because LBNL does not permit research with level 4 organisms. Level 3 is included however, because LBNL does allow work to be performed which requires Level 2+ containment. Level 2+ requires the use of Level 3 procedures and practices in a Level 2 facility.
