The construction industry is a high risk industry for noise related ill health. Many construction processes are noisy. If you have to raise your voice to have a normal conversation when standing about 2 metres apart, for at least part of the day, then noise levels on the site may be at a level which could damage health. There could also be a problem if there are sudden extremely loud noises on the site, such as from cartridge operated tools, or if at the end of the day you notice that your hearing is muffled or your ears are ringing.
Quality of life can be badly affected by noise induced hearing loss. For example, affected people may find that:
Eliminating noisy processes or substituting them for a less noisy process are the best ways of dealing with noise on a construction site. If this is not possible removing people from the noisy area and choosing quieter equipment can also be effective. As a last resort, hearing protection and hearing protection zones may be appropriate.
Here are some examples of how you can reduce noise:
No. It is not acceptable to rely on hearing protection alone to control exposure to noise. Hearing protection should only be used when extra protection is needed above what has been achieved using noise control techniques such as elimination of noisy tasks, substituting quieter processes, removing people from noisy areas and selection of quiet equipment.
If, after taking these measures, hearing protection is still required:
In many cases a risk assessment for noise at a construction site can be prepared without using equipment to measure the noise levels. The assessment must be based on reliable information though and should include a realistic estimate of the employee’s exposure.
You may find it useful to observe work activities, measure the exposure time over part of the day and use this to estimate exposure during a full shift. If an employee is exposed to noise from more than one tool or work process during a typical day, you will need to collect information about the likely noise level(s) and exposure time for each source.
Information from manufacturers or suppliers about noise levels produced by the equipment can be used to calculate the daily exposure unless there is reason to believe it is not valid, for example if the tool is being used in a way not specified by the manufacturer or supplier, or in other circumstances where the noise exposure may be increased.
