LVRA: Right-Sizing Safety and Energy Efficiency

David Brummitt, 3Flow

The recent introduction of new human pathogens accentuates the importance of providing optimal building mechanical ventilation. Such an undertaking to right-size these systems can be complex, as laboratory applications and their ventilation risks are often unique, where a one-size-fits-all approach simply does not apply. The Laboratory Ventilation Risk Assessment (LVRA) introduces the concept of risk-based control banding to laboratory environments for developing minimum ventilation criteria for exposure control devices and laboratory environments, thereby taking the guesswork out of establishing risk-based ventilation parameters.

This presentation will describe the assessment process theory, elements, and applications of the LVRA. It will demonstrate how proper implementation serves as a critical first step in establishing customized airflow management for buildings.

Learning Objectives

  • Describe the assessment process theory, elements, and applications of the Laboratory Ventilation Risk Assessment;
  • Detail the steps required to effectively prepare for the performance of survey activities;
  • Understand the criteria used to develop control band values and associated minimum ventilation criteria; and
  • Comprehend the role of the LVRA as a critical first step in establishing customized airflow management for buildings.
