Tag: Biosafety levels

Biological agents are classified into four risk groups, ranging from RG1 (lowest hazard) to RG4 (highest). Understanding what is the difference between risk group 1 and 2 is crucial for maintaining proper laboratory biosafety and protecting personnel and the wider community.

According to the National Institutes of Health (NIH), a risk group 1 (RG1) agent is one not typically associated with disease in healthy adult humans. This classification is fundamental to laboratory biosafety, helping to define the minimal hazard posed by certain microorganisms used in research and diagnostics.
