Chapter 7–Room Ventilation, Makeup Air, and Pressurization Control Systems
Laboratory room exhaust provisions can become quite extensive, thus they should
be a focal point for the room ventilation system design. Adequate room exhaust
provisions must be provided to ensure removal of contaminated air from the various
containment units (that is, chemical fume hoods, biological safety cabinets, etc.) as
well as serve the other specialized exhaust needs. In addition, sufficient air must be
removed from the room in total to meet the laboratory room’s minimum ventilation
needs. In many cases, the total amount of air exhausted by all of the room’s exhaust
provisions exceeds the amount of airflow necessary to meet the room’s minimum
ventilation requirements and allow enough supply air to maintain the required room
ambient conditions as well. For these reasons, a laboratory room’s exhaust
provisions should be established first, then the room supply air provision may be
wholly dependent upon providing sufficient makeup air to balance the aggregate
room exhaust.
