Open plan laboratories, the availability of automated sensing and ventilation control technologies, and concerns about facility energy costs have all impacted the role of fume hoods in lab design in the 21st Century. These changes mean that relevant stakeholders need to reconsider traditional fume hood design goals and specifications. This session continues ongoing efforts to develop a basic guideline for selecting, specifying, testing and operating fume hoods for different lab environments. Rather than relying on a one size fits all approach and setting a single face velocity for all fume hood types the proposed guideline would evaluate how the hood is used, who is using the hood, available supply and exhaust quantities, energy saving targets, etc. to come up with recommendations for hood performance. We will investigate how to specify, procure and test hoods and how to manage ongoing testing and training after installation.

Learning Objectives

  • Determine the best materials of construction and hood features that impact maintainability for your hoods.
  • Evaluate the factors affecting performance and define required operating specifications and performance criteria.
  • Describe relevant test methods to ensure consistent operation following installation.
  • Determine the information users need to provide about their operation for optimal hood selection.
