A fume hood is a ventilated laboratory enclosure that removes harmful fumes, vapors, and airborne contaminants by drawing them into the hood and expelling them safely outside the building, protecting the user from hazardous substances. It features a protective glass sash, an exhaust fan, internal baffles to direct airflow, and often includes airflow monitoring systems for safety. Key Components

• Sash: A transparent, often counterbalanced, sliding glass window that creates a barrier between the user and the experiment, protecting from splashes and acting as a visual indicator of the hood's opening size. 
• Exhaust System: An integrated fan that pulls contaminated air from within the enclosure through ductwork and vents it safely to the atmosphere. 
• Baffles: Internal panels with slots or openings that direct the airflow, ensuring that vapors and fumes are efficiently captured by the exhaust system and preventing them from entering the laboratory environment. 
• Airflow System: A system that maintains a constant inward airflow into the hood's interior, creating a protective barrier, and a controlled outward flow of air.
