Section 722 Booster fans

This requirement ensures ventilation continues if the booster fan shuts down. However, if the main fan stops, the booster fan must also stop to ensure it does not create an air recirculation problem. In either case, continuous monitoring of run status and level provides timely notice of any adverse changes in operating status. Appropriate alarms in the permanently attended monitoring station should indicate problems with the booster fan.
