Ground-breaking technology to manage HAVS risk.

The HAVWEAR watch has been developed to assess and manage hand arm vibration (HAV) risks more easily and effectively.

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.

Reactec’s compliant HAV management technology can be accessed easily, for as little as £15.08 per month per HAVWEAR. Our Safety as a Service plan gives you peace of mind, hassle free monthly payments, spread over 3 years; there’s no capital expenditure, therefore no assets. Find out more about the SaaS plans available to you.

How it works

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.


Add RASOR to your HAV Management Tool Kit

Assigning a RASOR to either a field supervisor or team member, the RASOR will automatically gather live exposure data from all their teams’ health risk sensors within range, including but not limited to Reactec’s HAVWEAR watch.

The RASOR user and remote management will be automatically alerted to any exposure breaches for immediate over the shoulder intervention.

The RASOR transmits exposure data along with location information to the cloud based Reactec Analytics every 15 minutes so remote supervisors can have full visibility of their team’s location and exposure risk levels.

Read how RASOR can help companies achieve greater regulatory compliance while enhancing the health and safety of field operatives and lone workers.

Reactec Training Aid

Optimise in real-time tool operator productivity and risk, with the Reactec Training Aid App

The Tool Training App means supervisors can better manage productivity and risk than previously considered possible.

By combining the RASOR training aid and the HAVWEAR watch, supervisors can proactively optimise tool choices and usage by training colleagues to.

  • Improve operator tool technique
  • Better assess tool condition
  • Ensure the best tool for the job

The tool operator can change their tool technique such as grip, push force, etc to see if the effect increases or reduces their exposure risk.

While standing alongside a tool operator who is wearing HAVWEAR, the RASOR user can view the rate at which the tool operator’s exposure will be accumulated based on the real time vibration experienced by that operator.

Example of variation in exposure from tool use as shown using the training aid.

If the tool under test has the HAVWEAR Tool Tag attached then the Training Aid display will also compare the real time risk against what is expected of the tool via a simple but powerful traffic light visual aid. The visual aid will identify when the sensed level from HAVWEAR is materially different to the tool tag value.

Note the reading is updated approximately once a second and is not a rolling average over the time since activation. This contrasts with instruments designed to measure vibration dose which average the dose from the start of the test and do not allow for real time analysis of technique.

It should be recognised that the HAVWEAR watch real use data supplied to the RASOR is based on HAVWEAR sensed vibration reading. The HAVWEAR watch sensed vibration uses detected signals from a triaxial accelerometer in the device which are adjusted for transmissibility through the hand to give an approximation of the vibration magnitude incident at the hand. The reading as such does not meet the measurement requirements of ISO8041. However, the methodology is extremely consistent and will readily be able to determine relative risk levels for different uses of a tool or differences between tool types.
