Performance of exhaust-protective (class I) biological 'safety' cabinets.
Nineteen open-fronted (class I) safety cabinets were subjected to spore containment and airflow tests, which suggested that a flow of 0.75 m/s was the minimum required for safe operation; further tests on three of the cabinets were repeated at different air speeds and confirmed this. The airflow is required to overcome the effect of laboratory or external air currents. Contamination of surfaces...
متن کاملSafety of portable inoculation cabinets.
Laboratory work with pathogenic microorganisms should be performed in a ventilated safety cabinet. A minimum airflow of 0-5 metres per second through the working aperture has been recommended, with discharge of the exhaust air through a filter, then into the open air (Department of Health and Social Security, 1970). Such a unit must be permanently installed. There are possible advantages to a p...
متن کاملEvaluation of laminar flow microbiological safety cabinets.
The microbiological control efficiency of two class 100 laminar down-flow hoods was determined by using aerosols of Bacillus subtilis var. niger spores. The first unit challenged utilized a slanted eyelid to partially enclose the front work opening. This hood showed nearly perfect control of ambient organisms in the work area. It also gave a 10(6) or greater drop in the number of organisms pass...
متن کاملFluid dynamics of cytotoxic safety cabinets.
This study investigated the specific fluid dynamics characteristics of cytotoxic safety cabinets (CSC), particularly those used in cancer drug reconstitution operations. Measurements taken on site were used to derive characteristic data for these cabinets. An in-depth laboratory investigation of airflows inside another CSC was also conducted. Anemometric values recorded on these two installatio...
متن کاملValidation of peracetic acid as a sporicide for sterilization of working surfaces in biological safety cabinets
Objectives: This study aimed to validate the use of peracetic acid as sporicide agent to decontaminate the working surface of a laminar flow biological safety cabinet (BSC), as an alternative to glutaraldehyde, including the selection of the disinfecting agent, the method of application, and the contact time. Materials and methods: The test organism was the spore-forming bacterium Bacillus atro...
