This is an archived recording of the 2020 online version of the course. The course materials and continuing education credits and/or professional development hours are not available. This course is designed to educate Engineers, Industrial Hygienists, facility owners, and Researchers on the proper methods to design and evaluate laboratory exhaust systems to avoid adverse re-entrainment of the exhaust into nearby air intakes. Improperly designed exhaust systems (even those that meet prescriptive code requirements) can cause chemical and biological contaminant exposure levels to be higher at nearby air intake locations than they are in the actual laboratory; potentially creating unsafe conditions throughout the entire building and neighboring buildings. As part of this course, the attendees will learn basic guidelines on how to properly locate, size, and operate laboratory exhaust systems to minimize the potential for adverse re-entrainment of the exhaust. Implementing these guidelines is critical for maintaining adequate air quality within the laboratory, avoiding both short term health hazards, as well as improving the long-term health and welfare of all of the building occupants. This course will also provide information on how the energy consumption of these systems can be greatly reduced by applying smart technology to the control systems. The energy savings are often on the order of $0.50/cfm per year. These are funds that may then be available to expand the research opportunities, potentially allowing us to avoid or minimize the impact of future pandemics.

Laboratory Exhaust Stacks: Safe and Energy-Efficient Design

Click here to purchase
This is an archived recording of the 2020 online version of the course. The course materials and continuing education credits and/or professional development hours are not available. This course provides designers and operators of laboratories with wet lab exhaust systems with the proper methodology to ensure safe systems operation. Laboratory Exhaust Stacks: Safe and Energy-Efficient Design walks students through the entire design process. Energy consumption represents an important component of the course, as laboratories consume significantly more energy than a typical office building, due to laboratory ventilation systems. Training topics include how to properly locate air intakes and exhaust stacks and the various methods for applying variable-air-volume (VAV) control to minimize energy usage while avoiding adversely impacting the air quality. Attendees will calculate an appropriate concentration design criterion for a specific emission source and determine dispersion modeling techniques for particular applications.
