This Guideline provides risk-based biosafety practices for facilities handling Risk Group 1 (RG1) biological material.

This guideline updates and replaces all of the recommendations for Containment Level 1 (CL1) originally published in the Laboratory Biosafety Guidelines (LBG), and presents these recommendations in a format similar to the CBS.
