Table 4 Risk-based recommendations for biocontainment and associated mitigation strategies for low- and high-risk laboratory activities
Mitigation strategy | Lowa to Mediumb-risk laboratory activities | High-risk laboratory activities c |
|---|---|---|
Personnel protection | Gown Gloves Eye protection Covered shoes Avoidance of sharps | Respiratory protection Gown Gloves Eye protection Covered shoes Avoidance of sharps |
Primary containment | Class II BSC (annually certified) Aerosol generating procedures (i.e., centrifugation) devices with bioseal (gaskets buckets and corresponding lids (screw or clip type). Buckets may only be opened in the BSC | Class II BSC (annually certified) Aerosol generating procedures (i.e., centrifugation) devices with bioseal (gaskets buckets and corresponding lids (screw or clip type).
