EAR & EYE PROTECTION
HEAR ME OUT
With up to 30% of all workers being exposed to hazardous noise levels, Peter Dumigan, MD of the Hultafors Group UK, advises on the precautions employers can take to protect the hearing of their workforce.
Long term damage to your hearing can be caused by the noise from regular daily use of even the most basic hand tools – drills, angle grinders, disc cutters, circular saws, even hammers – if you don’t wear proper ear protection.
The Control of Noise at Work Regulations 2005 are designed to protect workers on site from the risks caused by noise.
Noise induced hearing loss is the most commonly reported occupational disease with more than 800 million people around the world are affected by the condition.
More than 30% of all workers are exposed to hazardous noise levels, and one in four manufacturing workers that are exposed to loud noise do not use hearing protectors.
Hearing damage caused by exposure to noise at work is permanent and incurable with research estimating that around two million people can be exposed to noise levels that are potentially harmful.
More often than not, hearing loss is gradual as a result of prolonged exposure to noise, but when combined with normal loss of hearing as you age it becomes a rapidly deteriorating condition.
As an added hazard, exposure to unsafe noise levels can also result in tinnitus, a permanent sensation of background ringing or buzzing your ears. But in the most serious of cases, immediate damage to your hearing can also be caused by sudden loud noises.
REGULATORY PROTECTION As far as the health and safety regulations are
concerned, the noise threshold for providing hearing protection is now a daily exposure of 85 decibels. More importantly, the level at which employers must assess the risk to workers’ health and provide them with risk information and training is now 80 decibels.
So, making the right, well informed decision is as important for the self-employed as it is for employers.
As an employer, you have to provide your employees with properly maintained hearing protectors if they ask for them and if their noise exposure is between the lower and upper exposure thresholds. You also have to make sure they use them properly and establish hearing protection zones where the use of hearing protection is compulsory.
DON’T TAKE YOUR HEARING FOR GRANTED Too often we take our health and wellbeing for granted

and probably never stop to consider what fantastic sensory organs our ears actually are. As well as helping us communicate, our hearing helps to keep us safe. It is one of the primary links to our surroundings and is vital for how we communicate with others.
Aside from issues with your mobile phone, think how you’d cope in hazardous situations if you couldn’t hear an alarm bell, a car horn or someone calling to you. We rely on our hearing in so many ways, which is why we should protect it.
Unfortunately, for a significant part of the population, this ability is partially or entirely lost, because of exposure to loud noise. Hearing loss can never be restored but avoiding damage to your hearing is in most cases a matter of selecting and wearing the proper protection.
Our hearing isn’t designed for many of the sounds we are exposed to today especially the unwanted sounds - those that can potentially damage your hearing. So remember, if you need to raise your voice or scream to be heard when standing about a metre from someone on site – then its more than likely that the noise around you is dangerous.
WHAT IS NOISE AND HOW DOES IT RELATE TO
WORKING ON SITE? Sites are noisy places. Not just your mates’ banter and the radio in the background, but the working environment. Machine tools all make noise, so does the process of using tools and applying fixings. It’s constant, almost incessant.
Working on site all the day means that noise is constantly being poured into your hearing. But what many people don’t realise is that every noise source and the length of time you’re exposed to it has an exposure level measurement and you’ll be surprised how quickly you can reach the maximum daily safety exposure dose without proper protection.
For instance, drilling into wood at 92 decibels would only give you 10 minutes safe exposure against your full day’s allowance. Drilling into metal creates 96 decibels of noise, a chainsaw 99 decibels, a circular saw 101 decibels, drilling into concrete 108 decibels and an angle grinder 109 decibels.
So, take a look at the chart (see top of page 21) and you’ll see that if you haven’t got proper hearing protection, you shouldn’t be on site working and handling tools for very long at all.
