A Biohazard Cabinet, also known as a Biological Safety Cabinet (BSC), is a specialized workspace used to handle biological materials in a controlled and safe environment. It is commonly used in laboratories for work involving infectious agents, hazardous biological substances, or sterile techniques.
Types of Biohazard Cabinets:
- Class I:
- Provides protection for the user and the environment but not the sample.
- Airflow is directed away from the user, and exhaust air is filtered through HEPA filters.
- Class II:
- Offers protection for the user, environment, and sample.
- Airflow is carefully controlled and filtered to maintain sterility.
- Commonly used in clinical, pharmaceutical, and research labs.
- Class III:
- A fully enclosed system offering maximum protection.
- Gloves are used to manipulate materials inside the cabinet.
- Often used for handling highly infectious agents.
Key Features
- HEPA Filters: High-Efficiency Particulate Air filters trap airborne particles, preventing contamination.
- Laminar Airflow: Maintains a sterile working environment by directing airflow in a specific pattern.
- UV Light: Some models have UV light for sterilizing the workspace when not in use.
- Sealed Design: Prevents leakage of hazardous materials.
