Labs: Ventilation Strategies

Truly constant volume laboratory ventilation systems are almost obsolete, but there is a wide range of “nearly constant” systems that respond in steps to users’ activities and needs. These systems, sometimes called two-state or two-position constant volume systems, offer many options to ventilation designers.

The ventilation strategy should fit and support the safety programs for the laboratory. Ideally, the ventilation designer and safety officer work together to produce a coherent program of exposure control.
