In varying degrees a laminar flow biological safety cabinet is designed to provide three basic types of protection.
Uses and principle of operation of biosafety cabinet.
The purpose of containment is to reduce or eliminate the exposure to potentially hazardous agents of laboratory workers other persons and the outside environment.
This chapter discusses the purpose principle of operation specifications and applications of biosafety cabinet bsc.
The video describes the biosafety cabinet its principles operation uses maintenance calibration and safety methods.
Improved principles ofbiological safety cabinet design true laminar airflow unidirectional airflow moving along parallel flow lines at a constant velocity minimizes air turbulence within the work zone.
Environmental protection from contaminants contained within the cabinet.
Follow these guidelines for working safely in a biological safety cabinet bsc.
A bsc serves as a means to protect the laboratory worker and the surrounding e.
Personnel protection from harmful agents inside the cabinet.
With proper techniques activities within the work area can be performed safely minimizing the chance of cross contamination.
Product protection to avoid contamination of the work experiment or process.
Improper use of a biological safety cabinet can result in contaminated cultures and expose workers to infectious organisms.
Primary containment which is the protection of personnel and the immediate laboratory environment from exposure to infectious agents is provided.
The term containment describes safe methods or properly managing infectious agents in the laboratory environment where they are being handled or maintained.
When used correctly a curtain of room air enters the grill at the front edge of the bsc work surface and acts as a protective barrier.
The terms biological safety cabinet and biosafety cabinet have been widely used to describe a variety of containment devices equipped with hepa filter s designed to provide personnel or both personnel and product protection from biohazardous materials.
The air mixes with the recirculating air stream and passes through a hepa filter downward toward the work surface creating a contamination free zone.
