Fundamentals of Chemical Fume Hood Safety

Category: Laboratories

A chemical fume hood is the main piece of laboratory equipment that protects laboratory staff working with hazardous chemicals. When properly used, fume hoods protect staff from inhaling chemical gases, vapors, and aerosols. They serve as a physical barrier between staff and the hazardous materials inside the hood, and provide some splash protection.

This basic-level eLearning course provides an essential understanding of the major components of a chemical fume hood and proper practices for its safe and effective operation. Topics covered include the major components and types of fume hoods and their monitors, maintaining proper airflow, daily use protocols and good fume hood work practices, and what to do if there is an emergency.


This online course is designed for public health and clinical laboratory staff, safety professionals, and persons interested in the safe use of chemical fume hoods as determined by your laboratory-specific risk assessment.


At the conclusion of this webinar, you will be able to:

  • Identify general facts about fume hoods
  • List factors that affect the proper fume hood airflow
  • Describe startup procedures prior to working in a fume hood
  • Describe proper practices for working in a fume hood
  • Describe finish procedures for completion of work in a fume hood
  • Describe the procedures to follow during an emergency
