Biosafetysuojakaapit, often referred to as biological safety cabinets (BSCs) or fume hoods, are enclosed workspaces designed to protect laboratory personnel, the environment, and the product during handling of biological agents. These cabinets provide a controlled environment by using HEPA (High-Efficiency Particulate Air) filters to remove airborne contaminants. They are crucial for preventing the spread of infectious agents and for ensuring the integrity of sensitive experiments.

There are different classes of biosafety cabinets, each offering varying levels of protection. Class I cabinets are primarily designed for personnel protection, with air being drawn into the cabinet and exhausted after filtration. Class II cabinets offer both personnel and product protection, with a portion of the air recirculated within the workspace after filtration, and the remainder exhausted. Class III cabinets provide the highest level of containment, featuring a sealed system with glove ports for manipulation of hazardous materials.

The selection of the appropriate biosafety cabinet depends on the type and risk level of the biological agents being handled, as well as the specific laboratory procedures being performed. Proper operation, regular maintenance, and certification are essential to ensure the continued effectiveness of these safety devices. Training personnel on the correct usage of biosafety cabinets is a fundamental aspect of laboratory safety protocols.
