Biological safety cabinets are necessary when working with biohazardous materials, or materials which may present aerosolized or vapor hazards. A biological safety cabinet (BSC) provides protection for biological samples, as well as for personnel and the work environment. They are used for a variety of applications in the life sciences as well as pharmaceutical, clinical, and industrial laboratories.
Whether it be in education or chemical manufacturing, biosafety cabinets are crucial to any workspace dealing with the study and handling of chemicals. Used primarily to protect from noxious or radioactive materials, biosafety cabinets serve as a safe space that both shelters a substance and promotes the observation of it. Standard biosafety cabinet classification contains the three main types of cabinet classes. These variations in biological safety technology contain similar designs (centered around a clean room HEPA filter) but vary among three general specifications: risk, inlet velocity, and protection capabilities.
Biosafety is the maintenance of safe conditions in biological research to prevent harm. The Centers for Disease Control (CDC) and the National Institutes of Health (NIH) established a set of biocontainment precautions to isolate dangerous biological agents. Biosafety Levels 1 through 4 provide laboratory practices and techniques to safeguard against harmful incidents. Failure to follow practices can lead to increased risk of exposure to biohazards or pathogens.
The International Standards Organization (ISO) is responsible for the latest classifications for clean room environments. These global standards, which have more classes than previous United States systems, are carefully judged, since the slightest error can often affect the sensitive materials that must stay in them. Because of this, you can only get cleanroom certification if you meet the standards in several categories. Here we have a brief explanation of the major categories in this process so that you can learn a bit about the subject before diving into your own classification process.
