A ducted fume hood is a containment device commonly found in laboratories and industrial settings. It is designed to capture, contain, and exhaust hazardous fumes, vapors, or particles generated during various processes to protect the user and the environment. Ducted fume hoods are equipped with an external ventilation system, typically connected to a ductwork system, which expels the captured contaminants outdoors or to an appropriate filtration system. This ensures that harmful substances are safely removed from the workspace, maintaining a safe and healthy working environment.
