Fans and ventilation systems can exceed noise exposure standards, making them dangerous for workers. This document advises how workplaces can manage noise by:

  • following a hierarchy of control measures
  • lowering noise levels by reducing air turbulence and mechanical vibration
  • using quieter fans and reducing their speed
  • improving ductwork to improve air flow and reduce vibrations
