Eliminating risk: One of the main reasons for the biosafety cabinet is to protect the client from any kind of contamination and open to the pathogen. Another significant factor to remember before using a biosafety cabinet is to ensure all the part of the machine is working accurately as biosafety cabinet acts an obstruction between the example and the external world if by any possibility it gets out this future risky for the remainder of the staff working in the lab.
So it is consistently important to check whether the filtration system is working or the cabinet is airtight or not before utilizing. A High efficiency particulate air filter: The exhausted contaminated the air from the cabinet is filtered by the HEPA filter. This filter traps all type of unsafe particles and irresistible agents like virus, bacteria or any harmful microorganism. Inbuilt ventilation system: As HEPA gives an obstruction against harmful agents and organism nevertheless it couldn't stop any destructive gas or chemical radiated from the cabinet.
Ventilation protects the client from this harmful gas and chemical which can be very destructive for the lungs if breathed in. Airtight cabinet: Another security proportion of a biosafety cabinet is that it is inherent water/air proof structure so no unsafe infections come out or goes inside the bureau. The airtight cabinet likewise traps unsafe gas emitted from the cabinet. Provide clean environment: It additionally give clean environment to culture cell which is utilized in treatment of fatal disease and medicinal purpose.
Give a large variety of cabinet: As a safety cabinet is partitioned into three classes it gives a variety of range and features to the client which they can pick as per their necessity and pocket squeeze. Yet, the class 2 cabinets are viewed as the most affordable and adaptable in nature and are utilized by the majority of the labs.
Provides with rubber gloves: Biosafety cabinets give elastic gloves and goggles which secure the experimenter against direct contact with the example. If the microorganism is unsafe direct contact with the hand and eye can cause serious health hazards for the client and can spread to the next stuff from the effected person.
All the features of the biosafety cabinet are partitioned into three classes of the cabinets.
Built in exhaust fan
High effectiveness particulate air filter (HEPA)/carbon filter
A front opening gap
A front opening with a consistent internal airflow
Double high effectiveness particulate filter (HEPA),vertical, double directional airflow
Inbuilt ventilation system
It allows different airflow patters
A class 3 biosafety cabinet is additionally separated into two kinds of cabinet type A and type B:
Down flow of high proficiency particulate filter
30% of the HEPA filtered air are delivered inside the lab or out in the environment(with or without thimble pipe connection)
70% of the leftover air are re-coursed inside the cabinet
Biologically contaminated plenum is encircled by positive pressure in the event of type A1 and negative pressing factor if there should be an occurrence of type A2.
HEPA filtered down flow
30% air is re-circulated in B1 type and no air is circulated if there should arise an occurrence of type B2
Hard ducted cabinet in outside ventilation system
