Biological safety hoods are equipment that provide protection for the operator against infectious agents. Their designs are vertical and horizontal, used in microbiology laboratories, which prevents the exit of bioaerosols from the work area.
Likewise, these teams keep the areas free of particles or possible contaminants, such as bacteria that alter the products with which they are working, as well as the health of the worker operating in it and the environment.
Functions of the Biosafety hoods
The protective mechanism offered by biological safety hoods is due to electromechanical/electronic elements (engine, fan, filter, ducts, lighting, etc.), and physical processes (laminar flow, pressure differences) that propel the air through special, strategically placed, large surface filters that have a minimum particle retention efficiency of 99.99%, when the particle size is on average 0.3 µm (micrometers).
In order to obtain efficient results, with respect to the safety offered by hoods and in conjunction with the health of the operator, certain procedures exist, including this one:
- Detail the work to be done, to coordinate with the environment and avoid interruptions while the equipment is in use.
- Make sure the equipment is turned on, and allow air to flow freely.
- Handle materials and equipment safely in the laboratory, using only the material required to perform the procedure.
- Keep the equipment disinfected, removing the appropriate materials.
- Turn off the biological safety cabinet, closing the floodgates and turn on the ultraviolet lamp.
All these procedures, respond to the safety of the practices carried out inside the device.
