Introduction to fume hoods


Fume cupboards, often known as fume hoods, fume cabinets or fume filtration cabinets (these terms will be used interchangeably on this website) are localised fume extraction systems which are fitted into scientific and medical laboratories to protect users from harmful substances that could be inhaled. They should not be confused with fume extractor systems which tend to be larger installations affecting the whole environment. There are two main types: ductless fume hoods (re-circulating fume hoods) which rely on filters and ducted fume hoods which expel the fumes to the atmosphere outside.

Regulations affecting fume cupboards

The control of exposure to harmful substances is governed by the Control of Substances Hazardous to Health (COSHH) Regulations 1999 (1). These regulations cover laboratory fume cupboards and other fume extractors which discharge into the atmosphere and re-circulating fume cupboards as well as microbiological safety cabinets and fume extracting systems such as those used in welding.

Localised fume extractor systems used for work with harmful gases and chemicals must meet minimum requirements of the British Standards. Where fume hoods are only used to control low levels of fume, dusts or noxious smells, the strict British Standards do not apply.
