Biosafety laminar flow cabinet or hood is used to maintain a clean environment when performing microbiological investigations. The hood also protects the worker or scientist from a direct contamination with the organisms or materials they are working with.
It provides the perfect environment for the handling of pathogenic microorganisms or infectious specimens; and the hood excludes all forms of contamination during experimentation in the laboratory.
Biosafety laminar flow cabinet or hood (Figure 1) is an immovable piece of equipment, and fragile laboratory equipment, and thus it should be sited in places within the laboratory where they will not be moved from one point to another.
The hood provides a secure environment for conducting experiment and for the manipulation of microorganisms (especially pathogenic microbes). Working in the hood minimizes infection of the researcher and the escape of pathogens to the environment and/or laboratory room.
MAINTENANCE/CARE OF THE HOOD
- Users of the hood should always read the owner’s manual before usage.
- The hood should be properly cleaned and disinfected after use.
- The UV light in the hood should only be put on when no work is being performed in the biosafety laminar flow cabinet.
- Microbiologists working in the biosafety laminar flow cabinet must always ensure that the glass covering in the hood is kept at the recommended levels during experimentation.
- The hood should be properly covered after experimentation.
