What is a fume cupboard?

A fume cupboard (sometimes called a fume cabinet or fume hood) is a type of protective enclosure used in laboratories. Its function is to protect operators and other personnel by providing containment. It is designed to limit the escape of airborne contaminants while protecting the product or experiment. These contaminants can include hazardous, toxic and/or flammable fumes, gases, and vapours/aerosols.

Typically, it has a metal body, a chemically resistant chamber, and an adjustable front opening (sash). The sash is made from safety glass. An exhaust fan pulls air and airborne contaminants through connected ductwork to an external discharge point where they can be safely dispersed at low concentration.

If external discharge is not viable, recirculation filtration fume cupboards are available. These provide operator and environmental protection from contaminating fumes and a limited quantity of particles through filtration systems within the fume cupboard.

In the UK, fume cupboards should be designed to meet BS EN 14175. They should be tested at least every 14 months to comply with COSSH Regulations.
