What is the function of a fume hood in the laboratory?

The function of a fume hood in the laboratory is to provide a safe environment by expelling hazardous fumes. Fume hoods are designed to protect laboratory personnel by capturing and expelling harmful vapors, gases, and aerosols that might be generated during experiments. By ensuring that these substances are vented outside of the building, fume hoods help to maintain air quality within the laboratory and reduce the risk of inhalation exposure to toxic or flammable substances.

In addition to protecting the health and safety of the users, fume hoods also help to contain spills and reduce the likelihood of accidents involving volatile compounds. Their design typically includes a controlled airflow and a sash that can be adjusted to the optimal height for safety and visibility while working. These features make fume hoods an essential component of laboratory safety practices, particularly when working with hazardous materials.
