Biological safety cabinets are one of the most useful equipment for laboratories. It is an enclosed, ventilated workspace under negative pressure that is equipped with (HEPA) high-efficiency particulate air filters. It is used in laboratories while working with biologically hazardous materials for personal protection, product safety from the environment, aerosols, and contaminations. Here are the three states of protection offered by the Biosafety Cabinet.
- Personal defense against dangerous substances within the cabinet
- To prevent sample contamination, use product protection.
- Environmental protection against the cabinet’s internal pollutants
3 Types of Biological Safety Cabinet
The biological safety cabinets are divided into 3 classes, where each group defines the type of protection:
Class I biological safety cabinet
There is airflow from the area within the cabinet through its open front entrance. It is possible to cover the opening with a lid and gloved hands. The cabinet solely safeguards the environment and the worker.
The product’s sterility is not safeguarded by this cabinet. The worker’s protection is provided by the airflow from the room inside to the hood through the front aperture.
Class II biological safety cabinets
Vertical laminar airflow is present inside the cabinet, and the front entrance is open. This hood offers defense for the product, the environment, and the worker. The airflow from the room to the hood space is the basis for the protection provided by this cabinet.
Class III biological safety cabinet
Enclosed are glove boxes. A HEPA filter is used to filter all air, including entering in and exiting out. The environment, the worker, and the product’s sterility are all given the highest level of protection.
Safety Points
The task must be planned out in advance, and a labeling list of the necessary tools, supplies, and steps must be created.
-Don’t mess with the air barrier.
-Avoid relocating any of the other guests.
– Carry out the task calmly.
-Make use of the air’s one-way flow. Use sterile working methods.
-Only place the tools and supplies that are required.
-On the cabinet for at least five minutes prior to beginning work.
-After finishing the task, wait an additional three minutes for the air to rinse.
-Delay the equipment’s rinsing in the filtered air for an extra three minutes.
Choosing the right Biosafety Cabinet
You must ask the following questions:
- What sort of biological element does each risk category have?
- Are there any other dangers besides biological ones, such as chemical or radiation concerns?
- Is the experiment itself required to be defended?
- Does the workplace have any unique requirements?
- What is the minimum working width for the cabinet?
- Should the numbers of aerosols produced during the experiment be restricted?
These are some of the important things to understand about the biosafety cabinet. Following the safety rules are some of the major points to remember.
