HAVWEAR - Hand Arm Vibration Monitor (HAV)
The HAVWEAR watch has been developed to more easily and effectively assess and manage hand arm vibration (HAV) risks. The HAVWEAR watch is a wrist worn device to advise workers of vibration exposure risk. The HAVWEAR watch 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; pre-defined tool vibration magnitude and vibration magnitude sensed by the wearer at the wrist. Either of these methods can be used to display HAV risk exposure points and both types of data are stored online for analysis by employers.
- Wrist worn device for truly personal monitoring experience

- Automatic manager alerts from the Reactec Analytics of excessive exposure
- Automatic manager KPI reports from the Reactec Analytics
- Real-time exposure points calculation & display
- Personalised exposure threshold display & multi haptic alerts
- Employees alerted even if colour blind or wearing hearing protection
- IP67 rated with extensive heritage of use in arduous environments
- 33 minute HAVWEAR re-charge
- Low cost, simple to use and fully automated
The HAVWEAR watch simultaneously at all times gathers HAV exposure data based on two methodologies - TEP and SEP. Only one is displayed to the operator - a choice made at a company level. The data is automatically transmitted to the Reactec Analytics by a docking station or RASOR. Within the Reactec Analytics your choice of exposure assessment method will be reflected in the HAV reports to standard users. Additionally your subject matter experts can view both sets of data to gain unprecedented insight to real use HAV risk drivers.
Tool Exposure Points (TEP) are calculated using the HSE risk assessment Exposure Points system, combining the length of time a tool is in use (trigger time) with the vibration value that is programmed on the HAVWEAR Tag. The validity of the value programmed in the HAVWEAR Tag is a responsibility of the employer to be “representative of the tool use by their operators”. A number of sources for the pre-defined magnitude can be used and the HSE will look for justification of choice.
Sensed Exposure Points (SEP) are calculated at the same time by the same HSE risk assessment methodology except that the vibration magnitude is real-time vibration magnitude as determined by HAVWEAR. The HAVWEAR watch takes a precision measurement at the wrist and corrects this measurement for the transmissibility through the hand. This yields a good real-time approximation of actual risks faced. If SEP is used as the sole assessment it should be done on the basis of being confident that the assessment does not under-assess the vibration magnitude. There is ample guidance from HSE on typical tool vibration magnitudes to allow a determination on the suitability of HAVWEAR sensed vibration magnitude.
