Performance Analysis of Class Ⅱ Biosafety Cabinetry in Veterinary-related Research Institutes

Abstract

ObjectiveTo detect the performance and use of class II biosafety cabinets in laboratories of veterinary-related research institutes.MethodsA total of 126 class II biological safety cabinetries being used by three veterinary-related reseatch institutes in Harbin were tested. The performance indicators were judged according to the test results and and analyze according to relevant standards, in order to understand the use of biological safety cabinets.ResultsThe overall pass rate of 126 biosafety cabinetries was 17.5%. The total qualified rate were 100%, 100%, 100%, 100%, 49.2%, 92.9%, 68.3%, 22.2% and 100% ,respectively in terms of the appearance of integrity, cleanliness of work area, integrity of high efficiency filter for supply and exhaust air, flow pattern, the velocity of inflow, the velocity of the downdraft, noise, illumination and alarm and interlock system of class II biosafety cabinet.ConclusionThe overall pass rate of biosafety cabinetries in some veterinary-related research institutes is low. Regular inspection, operation and maintenance management should be strengthened to eliminate biological safety hazard timely and prevent infection accidents of laboratory.
