Assess real life risk of HAV exposure

Without accurate knowledge of operator daily exposure, the likelihood of safely applying controls to keep HAVs exposure below required levels is extremely low due to the unpredictability of most work processes.

It is also widely accepted that manual assessments of exposure in the workplace, following regulations, will have a high level of uncertainty. This can influence actions to reduce risk as well as assessing their effectiveness at a later date. Hence digital monitoring is critical to reduce this significant uncertainty on a representative exposure and help reduce HAVS risk as low as reasonably practicabable.

HAVwear system automates the whole process from calculating HSE exposure points in the field to viewing online reports. The reports include individual worker exposure and related tool use to pinpoint exposure hot spots. Also over the longer term the Reactec Analytics Platform to be used to manage the exposure of the whole works force and so impact positively on health management.



The HAVwear is a wrist worn device which informs the wearer of their exposure by calculating and displaying in real-time their HSE HAV risk assessment exposure points. Sound and vibration alerts inform the wearer if their personalised exposure thresholds have been exceeded.


It has ground breaking technology to
simultaneously assess exposure risk using;

Either of these methods can be used to display HAV exposure risk points and both types of data are stored online for assessment by employers.

Personalised assessment of individuals is essential to ensure no operator is being exposed to higher levels of exposure than anticipated. This can be through poor practise or lack of management of controls. The HAVwerar system supports this as part of the process to be compliant requiring no additional workload.

The HAVwear system helps by;

1. Personalised threshold management .

Tool operator’s allowable exposure limits can be customised for individuals. This can allow operatives with early stage Hand Arm Vibration Syndrome who may have been removed from tool use completely to return to work but on a restricted and controlled basis. Also with a clear reporting ability to see who is at greater risk, occupational health screening can be prioritised or the frequency adapted to reflect individual risks from vibration. This supports a more predict and prevent strategy instead of confirming new HAVS cases.


2. Viewing vibration trend helps identify higher than expected sources of exposure or more robust use of tools to help assess risk.

The HSE state "Effective maintenance can make big differences to vibration levels.  Loose or worn parts of tools and plant create extra vibration. Blunt, damaged or inefficient tools have increased vibration and also mean tasks can take longer, increasing exposure levels." Taking advantage of the HAVwear’s unique ability to assess tool vibration in the field, the HAVwear reports can highlight poor performing tools or operator tool use. Also comparing assets to select the lowest vibration tools for a job is made simpler and if the value of a tools vibration magnitudes need to be revised to be more representative in the field.

3. Auto alerts of workers exceeding thresholds

Alerts can be sent to any specified recipients when operators breach an action threshold to support proactive HAVs Management. A more rapid intervention by team leaders or managers to address issues, supports a proactive intervention unlike paper based monitoring which may only be assessed each month or quarterly.


4. More accurate and frequent assessment provides a more holistic view of risks and supports individual worker welfare long term

Timely assessment for continuous improvement is essential no matter what the level of vibration. Through a clearer understanding of the source and levels of exposure; related working practises; tool utilisation and performance; the HAVwear system will provide greater representation and insight to aid designing out exposure through work and tool planning. To make what was once difficult or inaccurate, reasonable and practical.

“The HAVmeter system has been in use on several of our contracts throughout the UK for over 16 months and has made the capture of exposure data very easy and accurate, facilitating appropriate management of Hand Arm Vibration. The most significant improvement has been in the efficiency and ease with which we now report and monitor exposure to Hand Arm Vibration throughout the whole business. Accurate exposure reports can be generated in seconds giving us as much detail as we require both at contract and board level.”
