A business must manage the risk of hearing loss from noise and ensure the noise a worker is exposed to does not exceed the exposure standard (an eight-hour equivalent of 85 dB(A) or a peak of 140 dB(C)), applying the hierarchy of controls. Those who design, make, import or supply plant must have it designed and built for the lowest practicable noise emission and give information about it. Where a worker is required to use hearing protection to protect against noise above the standard, the business must provide audiometric testing within three months of starting the work and at least every two years.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
