Laboratories are designed to achieve effective, safe, efficient, and sustainable environments for research and production. EHS personnel are often called upon to establish the design and operating specifications for fume hoods and laboratory ventilation systems. Establishing guidelines, selecting appropriate exposure control devices, and ensuring proper performance requires an understanding of the short- and long-term needs of researchers, hazards, and how to properly employ engineering controls. This process requires review, assessment, selection, and testing of exposure control devices to ensure proper design and operation of the lab ventilation systems.

Recorded in June 2020, this PDC provides industrial hygienists and EHS personnel with the tools and information necessary for participating in the design of lab ventilation systems, testing and commissioning, optimizing energy performance, and implementing a laboratory ventilation management program.

Course outline

  • Design and Operation of Modern Laboratory Ventilation Systems
  • Understanding Risk and Selecting the Right Exposure Control Devices and Systems
  • Establishing Airflow Specifications that Maximize Safety and Reduce Energy Consumption
  • Methods for Testing Performance of ECDs and the Lab Ventilation Systems
  • Implementing a Lab Ventilation Management Program

Course outcomes

Upon completion, students will be able to:

  • Identify the components of a lab ventilation system and the impact on lab safety and energy efficiency.
  • Determine the factors that affect the performance of lab ventilation systems.
  • Establish appropriate design and operating specifications.
  • Evaluate risk for the selection of appropriate exposure control systems.
  • Develop the elements of a comprehensive LVMP.
  • Implement the LVMP in accordance with the ANSI/AIHA Z9.5.
  • Apply test methods and criteria for fume hoods, ECDs and lab ventilation systems.

Who will benefit

EHS personnel called upon to establish the design and operating specifications for fume hoods and laboratory ventilation systems.


Attendees should have an understanding of the fundamentals of laboratory fume hoods and exhaust systems with regards to the work and chemicals used in laboratories.

Time to complete

Participants will have 90 days from the date of purchase to view the session recordings and submit the online evaluation for credit.
