Fume Hood is a piece of laboratory equipment used to protect laboratory workers and the surrounding environment from hazardous chemicals, vapors, and gases. It is typically a large cabinet that has a fan or blower system that pulls air from the front opening of the hood, through the work area, and out of the laboratory through an exhaust system. They can also be designed to meet specific requirements for chemical resistance, fire protection, and other safety features. Fume Hood is designed to contain and control the release of hazardous materials by creating negative pressure inside the hood.
