Pioneering technology and medical research into Hand-Arm Vibration exposure risk.

Reactec are pioneers in developing innovative technology to safeguard employees’ and employers from exposure to everyday risks in the workplace.   

Our papers are free to download and provide cutting edge research to help you better understand the human impact of HAVS and importantly the legal requirements of The Control of Vibration at Work Regulations 2005 and related HSE guidance.     

Our work has involved leading academics in the field of the human response to vibration and local universities.  We also involved The Institute of Occupational Medicine (IOM), the leading provider of health and safety solutions to industry, commerce, public sector and professional bodies within the UK to bring independence and authenticity to validation work.

Assessing correlation of human response to vibration through vibrotactile threshold shift with vibration exposure determined on the subject. 

The research findings contribute to the development of wearable vibration exposure monitoring devices as a means of capturing authentic in-situ work environment operative exposure.  The results presented demonstrate that the assessment of vibration transmitted to the operator using wearable technology is positively correlated with the human response as …

Could deviation from static and declared vibration dosage assumptions in the real use by workers of power tools be preventing further progress on reducing HAVS in affected populations?  

The wearable sensor has been developed to calculate a transformed vibration dose which is equivalent to a vibration dose measurement made on a tool handle, by way of correcting algorithms. Independent research, (Graveling et al 2018), has been published on the validity…

Summary of the requirements of The Control of Vibration at Work Regulations 2005 and related HSE guidance, with respect to assessing daily exposure to Hand-Arm Vibration 

Of greatest importance, due to some market confusion, is to highlight that the HSE’s response to Q7 of the Q&A on vibration exposure monitoring should not be considered in isolation. The response is only in reference to the measurement of vibration magnitude, which the HSE advise is not a legal requirement for employers when assessing HAV exposure risk if other suitable data is available.




An independent report by the IOM on the validity of the data produced by Reactec’s  HAVwear to inform a suitable and sufficient risk assessment

The Institute of Occupational Medicine (IOM) was requested by Reactec to conduct an independent review of data collected using the HAVwear system and subsequently provided a report in January 2018.


The Institute of Occupational Medicine (IOM) was requested by Reactec to conduct an independent review of data collected using the HAVwear system and subsequently provided a report in January 2018.  The IOM review concluded that data gathered by the HAVwear system provides a useful source of information to inform a suitable and sufficient risk assessment. Also that data gathered on a regular basis can inform the development of risk reduction control measures and can be used to identify trends in risk reduction as part of a risk management program.   


The IOM is also of the view that, as the HAVwear system assesses vibration exposure during the entire use of the tool, it may therefore be more accurate than the use of trigger times and manufacturer’s data or other data sources compiled for a limited range of tool activity.




Necessity of wearable personal vibration exposure meters for preventing hand-arm vibration syndrome

The ISO 5349-1 standard, 2002/44/EC directive, and Japanese guidelines are focusing to the vibration magnitude of the tool handle. This vibration magnitude evaluation is assuming that when the different worker will use the same vibration magnitude tool, this means that the human response to vibration effects is the same  In this paper, we showed the data … 

The event was held at the Nagoya University (Daiko Campus) on the 13-15 September 2017. Reactec co-presented with Dr Setsuo Maeda and below is a full download of proceedings which includes the presentation.

Investigating the utility of wrist worn vibration monitoring in the effective management of exposure to dangerous vibrations within the work place


This paper seeks to demonstrate the validity of vibration data acquired from a personal wrist worn vibration monitor in assessing exposure to hazardous Hand Arm Vibration. The paper also seeks to define the value that data from continuous monitoring can have in forming an effective risk management process within the work place. Illustrated within this paper are some of the shortcomings arising from over reliance on single point sample measurements and the deviation between the perceived exposure calculated from a single point measurement and the reality of true exposure given the variability across time, task and a large cohort of individuals.




Hand-transmitted vibration assessment on the human as an indicator of health risk


The investigation concluded that wearable sensors can be useful as an indicator of potential harm to the individual.  The research also concluded that the effects of human interaction with the tool on potential risk faced by the operator are not adequately captured by existing methods and that wearable sensors may be useful in addressing this limitation.




Is real-time monitoring effective as a control measure to prevent Hand Arm Vibration Syndrome?


A wearable devise can be effective in controlling exposure levels when an individual is alerted to their exposure levels. Monitoring data can be a useful source of information for informing tool selection, process controls and personnel skills.




Can we prevent HAVS by using Declared Vibration Emission Value?


Many countries are using the tool vibration declared values based on the ISO 28927 series or following ISO5349 for preventing HAVS. It is clear that the values from these test protocols do not consider all factors in real work conditions.  These results indicate that a new evaluation method or equipment is needed to provide a more realistic and practical.







ATR Group - Keith Moorhouse, Managing Director

"Now we’re not just dealing with our clients’ tool assets, we’re dealing with their people – providing outsourced HSE support with respect to HAV monitoring and recording. The fact that HAVmeter empowers employees to manage their exposure in real time, and automatically collects the HAV data, gives ATR Group a strong foundation to support clients in the adoption of best practice in HAV management.”
