Noise Risk Assessments & Monitoring (SANAS Accredited)
Noise can be defined as annoying, or unwanted sound. Measuring noise levels and employees’ exposure to noise is the most crucial part of a workplace hearing conservation program. It identifies areas where there are excessive noise levels and employees who may be exposed to noise levels that may cause hearing loss. This information then helps determine appropriate noise control measures that must be put in place.
According to the Noise-induced hearing loss regulations promulgated under the Occupational Health and Safety Act, all employers need to assess the risk of noise exposure for their employees. Once the risks are quantified and evidence exists that noise exposure may be at or exceed the noise rating limit of 85dB(A), a monitoring programme needs to be designed and area measurements need to be taken so that noise zones can be demarcated. Once these demarcations are made it is the responsibility of the employer to reduce noise liberation and exposure by implementing controls.
Noise is one of the greatest risks most industries face and noise-induced hearing loss is one of the most common occupational disease for which compensation payouts are made.
