Designed to limit exposure to hazardous or unpleasant aerosols. First used by alchemists 500 years ago. (Modified from University Of South Carolina. ). The chemical fume hood is the most important engineering control that removes hazardous fumes and other air-borne contaminants in a laboratory worker’s breathing zone.  Any procedure or experiment that involves the use of hazardous chemicals needs to be contained inside a fume hood to control the release of contaminants in the laboratory.  If you plan to work with chemicals that release toxic, corrosive or flammable fumes, mists or particulates, you must handle these materials inside a chemical fume hood.  It is necessary to follow these guidelines to optimize the performance of the chemical fume hood.
