A Comprehensive Guide to Laboratory Fume Hoods A fume hood protects against dangerous or toxic gases, vapours, or airborne particulates by providing safe ventilation. A chemical fume hood is primarily intended to protect the user or the environment outside the hood in laboratory and production settings, but it can also be used to protect the materials or experiment inside the hood. To safely ventilate outside the building, duct fume hoods link to a remote exhaust system. A built-in fan and filtration system in ductless fume hood configurations filters and recirculates cleansed air.
