Sections 23 to 25 of the WHS Act and Regulation 59 require a manufacturer of plant or structures for use at work to ensure, as far as is reasonably practicable, that what it makes is free of risk to health and safety. If noise cannot be designed out, the manufacturer makes the plant so that its emission is as low as reasonably practicable and sees that the manufacturing process adds no new noise hazard, applying and testing the safety measures the designer specified and using materials and methods that bring noise down to the lowest level reasonably practicable. The manufacturer hands importers and suppliers the noise emission values, the operating conditions and methods used to measure them, and any conditions for safe use.
