  • BSL-3/ABSL-3 HVAC and Facility Verification

    It is the policy of the Centers for Disease Control and Prevention that a BSL-3/ABSL-3* facility is required to have a ducted air ventilation system. (*Note: This policy statement is only applicable to entities working in a BSL-3 laboratory with an organism that requires BSL-3 containment. This policy does not apply to entities working in a BSL3 laboratory with an organism that does not require BSL-3 containment.) This system must provide sustained directional airflow by drawing air into the laboratory from “clean” areas toward “potentially contaminated” areas. The laboratory shall be designed such that under failure conditions the airflow will not be reversed.
