A chemical fume hood protects lab workers by venting solvent fumes and other harmful gases out of the laboratory and the indoor room air. Air flows into the cabinet beneath a movable sash at the front, and carries fumes up and out through the vent. Bypass fume hoods have an additional air intake above the sash which minimizes disruption of air flow in the work area due to movements in and out of the hood. Options in chemical fume cabinets now include energy efficient low flow fume hoods and hoods with an outdoor air intake (also known as auxiliary fume hoods) to avoid venting conditioned room air. Chemical fume hoods designed for specialized uses such as working with radioisotopes or perchloric acid are also available.
