    Activities involving infectious agents and rDNA are assigned to a specific biosafety level based on the potential hazards presented. There are four biosafety levels recognized by the Centers for Disease Control (CDC) and the National Institutes of Health (NIH). Each of the four biosafety levels specifies microbiological practices, laboratory facilities, and safety equipment.

The IBC may also prescribe special conditions, requirements, and restrictions necessary for safe storage, handling, or transfer.
