The University of North Carolina at Chapel Hill is committed to providing engineering controls that minimize exposure to hazardous materials to students, faculty and staff who work in laboratories. These controls include biological safety cabinets (Chapter 16) and laboratory hoods. Laboratory hoods are also known as “chemical hoods”, “fume hoods” or simply “hoods”.

If you believe your hood is not working properly, contact Environment, Health and Safety at 919-962-5507 and ask to have your hood evaluated. You must review the UNC Hood and Laboratory Ventilation Policy listed later in this Chapter if you are considering the installation of a new hood.

Laboratory hoods are only effective if the hood operates properly AND the user exhibits good work practices. Refer to the section below entitled Laboratory Hood Work Practice Guidelines for more information.
