Recertification at specific intervals is required for which equipment?

• A. Clothes washers and dryers for scrubs and surgical drapes
• B. Refrigerators in the veterinary diagnostic laboratory
• C. The safe used for secure storage of controlled substances
• D. Biosafety cabinets located throughout the animal care facility and procedure areas

Answer: (D)

Periodic recertification is required for equipment that directly affects containment and personnel safety. Biosafety cabinets are designed to control airflow and contain aerosols, protecting personnel, the product, and the environment. Because airflow patterns, HEPA filter integrity, and sash performance can change over time due to wear, movement, filter changes, or maintenance, they must be recertified at defined intervals to confirm they still meet performance standards. A qualified technician tests airflow, containment efficiency, filter integrity, and sash operation to verify ongoing performance. This is why biosafety cabinets across the facility require recertification at regular intervals. Other items like clothes washers and dryers, refrigerators, or secure storage safes are important to maintain and verify (through maintenance, calibration, or security checks) but do not carry the same formal recertification requirement tied to containment and biosafety.
