Do you have a noise problem at work? HSE Guidance

Updated: Oct 7


Do you have a noise problem at work?


This will depend on how loud the noise is and how long people are exposed to it. As a simple guide you will probably need to do something about the noise if any of the following apply:

  • Is the noise intrusive - like a busy street, a vacuum cleaner or a crowded restaurant - for most of the working day?

  • Do your employees have to raise their voices to carry out a normal conversation when about 2 m apart for at least part of the day?

  • Do your employees use noisy powered tools or machinery for more than half an hour each day?

  • Do you work in a noisy industry, eg construction, demolition or road repair; woodworking; plastics processing; engineering; textile manufacture; general fabrication; forging, pressing or stamping; paper or board making; canning or bottling; foundries?

  • Are there noises due to impacts (such as hammering, drop forging, pneumatic impact tools etc), explosive sources such as cartridge operated tools or detonators, or guns?

Noise can also be a safety hazard at work, interfering with communication and making warnings harder to hear. Some examples of typical noise levels are shown in the graphic below.



The health effects of noise at work


Noise at work can cause hearing loss that can be temporary or permanent. People often experience temporary deafness after leaving a noisy place. Although hearing recovers within a few hours, this should not be ignored. It is a sign that if you continue to be exposed to the noise your hearing could be permanently damaged. Permanent hearing damage can be caused immediately by sudden, extremely loud, explosive noises, eg from guns or cartridge-operated machines.


But hearing loss is usually gradual because of prolonged exposure to noise. It may only be when damage caused by noise over the years combines with hearing loss due to ageing that people realise how deaf they have become. This may mean their family complains about the television being too loud, they cannot keep up with conversations in a group, or they have trouble using the telephone. Eventually everything becomes muffled and people find it difficult to catch sounds like 't', 'd' and 's', so they confuse similar words.


Hearing loss is not the only problem. People may develop tinnitus (ringing, whistling, buzzing or humming in the ears), a distressing condition which can lead to disturbed sleep.


Remember


By law, as an employer, you must assess and identify measures to eliminate or reduce risks from exposure to noise so that you can protect the hearing of your employees - The Control of Noise at Work Regulations 2005.


Where the risks are low, the actions you take may be simple and inexpensive, but where the risks are high, you should manage them using a prioritised noise-control action plan.

Where required, ensure that:

  • hearing protection is provided and used;

  • any other controls are properly used; and

  • you provide information, training and health surveillance

  • you review what you are doing if anything changes that may affect the noise exposures where you work

  • if in doubt, contact an occupational hygiene noise specialist for expert advice & guidance - enquiries@meridianenvironmental.co.uk - (01423) 549629
