What it contains
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
