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

The results demonstrate a stronger relationship between the hand transmitted vibration determined by the wearable sensor on the subjects and the human response to the vibration over the conventional measurement on the tool.  It could be further hypothesised that control measures derived from in-use tool data would be more effective in reducing the underlying risk to operatives (presented at the UKHRV 2018).




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 investigation shows that significant variances exist between HAV exposure calculated from assuming a static vibration dose and that determined from real use monitoring, indicating a potential for an increased risk of developing HAVS for exposed workers than expected (presented at the UKHRV 2018).




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.

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.
