At Vivid Air, we aim to supply the highest quality clean air and laboratory equipment South Africa has to offer.
There are various types of clean air equipment, each one with their own purpose and application.
However, in this article, we discuss biohazard safety cabinets, classes 1 and 2 in order to distinguish between their applications and some of their specifications.
The word is a combination between the words “biological” (relating to living organisms) and hazard (a danger or risk).
In medical terms, biohazard is defined as: “an infectious agent, or part thereof, presenting a real or potential risk to the well-being of man, animals and / or plants, directly through infection or indirectly through disruption of the environment.
In simple terms, a biohazard is a risk to human health or the environment (or both) arising from any work which involves coming into contact with microorganisms.
It’s a well-ventilated enclosure which provides protection to the person who is using it. It also protects the product and the environment from potentially harmful airborne microorganisms.
Class 1 biohazard cabinets are used for any work that involves handling microorganisms which are not known to cause disease in healthy adults.
The following are acceptable for class 1 biohazard cabinets:
Because the inward flow of unfiltered air from the laboratory can carry microbial contaminants into the cabinet, the class 1 cabinet is not appropriate for handling research materials that are particularly vulnerable to airborne contamination.
Class 2 biohazard cabinets are used for applications which require the handling of agents which are moderately hazardous and associated with different human diseases from mild to severe.
Class 2 cabinets are different from class 1 in the following ways:
