The “Definitive Articles” on Noise and Hand-Arm Vibration

Hearing Protection Generally Ineffective – HSE Research
HSE research shows that many exposed personnel wearing PPE get no protection whatsoever. They found, for example, that 40% of the workers expected to use hearing protection get negligible or zero protection. The implications of the findings published in this HSE report are far reaching as the common assumption that PPE is a reliable solution for personnel exposed to high levels of noise is simply untrue. This leaves many personnel still at risk and many companies open to indefensible hearing damage claims… Download noise tech note

Hand-Arm Vibration Assessment
Light Touch: HAV Assessment Best Practice – Health and Safety at Work Magazine – a substantial proportion of the time and resources designated by industry for hand-arm vibration risk management programmes is not well spent despite the best of intentions. The subject still appears to offer a minefield of opportunities for risk management mistakes based on misinformation and myth. This article offers a pragmatic guide to best – and cost effective – practice in HAV risk assessment. Download HAV tech note

HAV Management Audit: repeat vibration measurements – or best practice Action to reduce costs?
200 tools measured using a transducer attached with insulating tape… paying the supplier to measure all our tools every year… basing risk assessments on the Hire Association traffic-light system… The HAV Management Audit ensures that you avoid mistakes like these, generating a detailed Action Plan to update procedures to reflect current best practice. The most effective way to ensure compliance, it can also dramatically reduce the costs, resources and time required to manage HAVs risks. Download HAV tech note

Noise Assessment, Noise Control and Noise Purchasing Specifications

Think Outside the Box: Noise Control Best Practice – Health and Safety at Work Magazine
Noise control is a mandatory requirement under the regulations – but it needn’t necessarily cost much – or even cost anything at all. This article shows that if you approach noise control in the right way, you can not only reduce the typical assumed costs associated with noise control by up to 80%, but you can even reduce your operating costs.

Let the Quiet One In: Noise Buying Standard Specification – Health and Safety at Work Magazine
Implementing and policing a noise purchasing policy for new plant is a very cost effective element in any noise risk management programme. This article summarises the main factors involved in ensuring that buy quiet policies are both practical and effective with illustrates of the solutions to some of the common problems that can be encountered.

Sound Investment: Noise Assessment Best Practice – Health and Safety at Work Magazine
Currently, industry wastes a fortune on assessments that are little more than unnecessary annual or bi-annual “check-box” exercises. Moreover, the majority of these assessments are inadequate as they do not meet the minimum regulatory requirements. This article provides practical guidance on best practice to minimise the resources spent on assessment whilst, at the same time, ensuring that they are both effective and of high quality.Download noise tech note

Noise and Vibration Presentations

How to Recommend Self Financing Noise Control Instead of Ineffective PPE
International Occupational Hygiene Association (IOHA) Conference Paper: 27th April 2015

HSE research shows hearing protection is usually ineffective. This provides a wonderful opportunity for lawyers wrt hearing damage claims. As field PPE performance is so compromised, the best approach is to cut noise. This presentation shows how occupational health professionals can upgrade noise assessments by adding best practice noise control options and costs. Occupational health professionals are usually unaware of the new technology available that can reduce hearing damage risk at a fraction of the cost and is self-financing surprisingly often. The presentation provides a guide to re-imagining the noise risk assessment process (without engineering expertise) to generate the data for an initial evaluation of the noise control options, costs and benefits.

We also have a White Paper version of this presentation with more detailed content. I’d like a copy of the IOHA White Paper please >

“I attended your noise control workshop and had a great time, I found it both engaging and thought provoking.”  Trevor Laurent: Air Surveys Ltd.

Fan Noise Control Best Practice: CIEH November 2013

A guide to best practice in fan noise reduction – the most common source of environmental noise problems. Why BS 4142 doesn’t work well for classic low frequency fan tones. New technology that can often eliminate or reduce the requirement for high cost conventional techniques such as attenuators and enclosures. Reducing fan noise levels by improving efficiency as using aerodynamic techniques to reduce noise at source inside the fan itself. From huge industrial fans down to the smallest kitchen extract…

Noise Control Best Practice: Update (BOHS/HSE/IOSH events…): May 2013

New technology, innovative techniques and Self-Financing Noise Control projects across a wide range of  industries illustrating the typical 50% – 80% cost savings inherent in engineering noise control measures at source compared with conventional palliatives such as acoustic enclosures, silencers, lagging etc. The noise control modifications are often installed as an extension to maintenance and can be justified simply on the grounds of increased performance, efficiency and productivity, with noise reduction as an added benefit.

“One of the most impressive presentations I have ever seen” Mark Jones, Production Director Bakkavor

Chartered Institute of Environmental Health (CIEH): SE Region Spring Forum: April 2013

Defining BPM / BAT – for any noise issue
“Best Practicable Means” can mean different things to different people – particularly where the degree of specialised noise expertise varies. This presentation provides the pragmatic approach that must be followed by specialist or non-specialists alike to establish just what constitutes “best practice” and to assess the likely “Best Available Technology” to solve noise problems. Multi-media case studies are used to illustrate the key points.

“I thoroughly enjoyed your presentation and found it very insightful, especially since I am currently involved in dealing with the exact type of situation you described” E Senyah EHO  Reading BC

“…delegates provided excellent feedback for you as a speaker. I also thoroughly enjoyed your presentation as you were able to capture the audience with visual aids and a touch of humour.” Sara Weedon CIEH SE Region Executive Officer

Hand Arm Vibration Risk Management Best Practice: December 2013

This presentation is a pragmatic guide to current best practice in hand arm Vibration (HAV) risk management. It includes the myths surrounding vibration risk assessment, PPE (simple, there is none…) and other red herrings that can waste resources that would be better spent on risk reduction.
