A Current Consensus on Safety and Performance of Laboratory Hoods and Ventilation Systems

March 19, 2015
1 p.m. – 2 p.m.
Eastern Daylight Time


A Laboratory Fume Hood Summit was held at the University of California, Los Angeles (UCLA) in November 2013 to discuss the design, operation, and testing of laboratory fume hoods and ventilation systems. The summit's goal was to review and update consensus statements generated during a Fume Hood Workshop sponsored by Howard Hughes Medical Institute in 1998. The technology and standards for fume hoods and laboratory ventilation have changed significantly over the years with particular emphasis on improving lab safety and energy efficiency.

During this presentation, Thomas Smith of Exposure Control Technologies, Inc. and Louis DiBerardinis of Massachusetts Institute of Technology will provide an overview of the UCLA fume hood summit and describe some specific issues and consensus statements regarding:

  • Operation of variable air volume systems.
  • Establishing face velocity and minimum flow for fume hoods.
  • Specifying appropriate room air changes per hour for laboratories.
  • New methods to test performance of complex ventilation systems.
  • Training requirements for laboratory occupants and building maintenance personnel.

The purpose of the presentation is to share information and encourage discussion about ways to reduce energy consumption while better ensuring the health and safety of people in, on, or around laboratory buildings.

By participating in this webinar, attendees will:

  • Become familiar with current issues affecting laboratory fume hoods and ventilation systems.
  • Learn new technology and standards regarding design and operation of laboratory fume hoods.
  • Learn the factors affecting and controversy regarding establishment of minimum airflow specifications.
  • Learn new methods being discussed to evaluate and test laboratory hood systems.
