What are fume cupboards?
Fume cupboards, also known as laboratory chemical hoods, fume hoods, fume cabinets or film filtration cabinets, are pieces of scientific equipment, commonly used within biological, chemical and medical laboratories, that serve to control exposure to toxic, offensive or flammable vapours, gases and aerosols. Fume cupboards were invented over 100 years ago and, over the years, there have been many
refinements to the original Victorian design – but, despite refinements, the basic concept remains the same today. A fume cupboard in its simplest form is a cabinet with a moveable front sash made of safety glass. Fume cupboards were originally made from wood, but the most common material used today is epoxy-coated steel.
How do fume cupboards work?
Although there are many forms of fume cupboard, the basic principle is that a fume cupboard confines then expels hazardous airborne material. This is achieved by diluting the material with a large volume of air that is drawn into or passes through the fume cupboard. This diluted air is then exhausted and/or filtered and then expelled through vents in the unit or expelled outside the building, usually via vents on the roof. Proper use of the fume cupboard sash can also serve to shield workers from uncontrolled reactions.
