HAV Sentry | Real-Time HAVS & Hand Arm Vibration Monitoring System

Hav-Sentry

A wearable system that helps organisations understand, manage, and control hand–arm vibration exposure in real working environments.

Real-Time Hand–Arm Vibration Monitoring for Worker Protection

The HAV-Sentry System is a wearable vibration exposure monitoring system designed to help organisations prevent Hand–Arm Vibration Syndrome (HAVS), improve safety and wellbeing, and meet their obligations under the Control of Vibration at Work Regulations.

Supplied by Exactaform, HAV Sentry replaces manual estimates with real-time data, giving employers clear visibility of hand-arm vibration exposure as it happens across demanding work environments.

What is Hand-Arm Vibration Syndrome (HAV)?

Hand–Arm Vibration Syndrome (HAVS) is a serious, permanent occupational condition caused by prolonged exposure to vibration from vibrating tools, power tools, and heavy machinery.

Across the United Kingdom, more than two million workers are estimated to be at risk. In sectors such as manufacturing, assembly, construction environments, and wider industrial operations, repeated vibration exposure is often unavoidable without effective controls.

Common symptoms include:

  • Chronic numbness and tingling
  • Pain and reduced grip strength
  • Loss of sensitivity and dexterity
  • Discolouration of the fingers, commonly known as vibration white finger

Once established, HAVS is irreversible, making prevention, early detection, and accurate vibration exposure monitoring essential.

Hand-Arm Vibration Syndrome (HAVS) isn’t just a painful problem.

It’s a remarkably costly one which can have devastating impacts on your business, too.

£250,000+ average fine and compensation.

The average Health and Safety Executive (HSE)-inforced penalty for confirmed HAVS cases amounts to £250,000, but it can be upwards of £500,000.

Companies also face the responsibility of compensating affected employees, too an average of £18,000 per year for the duration of the employee’s career.

Health and Safety Executive (HSE) damnation.

Aside from the significant fines, the HSE also has the authority to name companies with confirmed HAVS cases publicly.

This can have a catastrophic impact on your ability to employ future talent, retain your current workforce, and gain access to Government-funded workplace schemes and grants.

Employee left with a chronic condition.

Worst of all, an employee’s quality of life has worsened because their employer did not have the right preventative measures in place.

The penalty and compensation costs, albeit high, can be recouped. However, once an employee has HAVS, they have it for life.

Why HAVS Monitoring Is a Compliance Requirement

Under the Control of Vibration at Work Regulations and associated British Standards, employers must:

  • Carry out suitable and sufficient risk assessments
  • Assess hand-arm vibration exposure during work activities
  • Ensure exposure does not exceed action or limit values
  • Apply proportionate Risk Management and control measures

Guidance from the Health and Safety Executive makes clear that employers must be able to demonstrate how vibration exposure is measured, controlled, and reviewed. HAV Sentry is designed to support this requirement with defensible, real-world vibration measurement technology.

HAV Sentry Glove and Wearable Technology

The HAV Sentry Glove integrates advanced wearable tech with purpose-built measurement devices designed for real industrial use.

Aegis sensing units embedded within the glove capture vibration directly from the wearer’s palm, ensuring accurate measurement at the true exposure point.

This approach delivers:

  • Consistent vibration measurement technology
  • Accurate tool and task-specific exposure data
  • Reliable performance in construction environments and industrial operations

How HAV Sentry Helps Prevent HAVS

HAV Sentry is a wearable monitoring solution that continuously measures hand-arm vibration exposure at the point of contact.

Using advanced measurement technology and vibration technology, the system captures actual exposure during real work activities rather than relying on manufacturer data or manual vibration log-books.

Key capabilities include:

  • Continuous vibration exposure monitoring
  • Automatic calculation of exposure levels
  • Immediate visibility of overexposure risk
  • Measurement data to support HAVS risk assessments and audits

This enables earlier intervention, before exposure becomes harmful.

Real-Time Monitoring and Alerts

Aegis sensing units within the HAV Sentry wearable measure vibration exposure continuously and in real time.

The system:

  • Measures vibration exposure as work occurs
  • Calculates cumulative exposure automatically
  • Compares results against defined vibration thresholds

If exposure approaches unsafe levels, the wearer receives immediate visual and audible alerts, enabling corrective action before limits are exceeded. This proactive approach reduces unnoticed overexposure and supports safer decision-making on site.

HAV-Sentry Dashboard and Digital Safety Oversight

All vibration data is securely transmitted to the HAV-Sentry Dashboard, a cloud-based monitoring and analytics platform accessible to safety practitioners, compliance teams, and operational managers.

The dashboard provides:

  • Clear visibility of workforce vibration exposure trends
  • Defensible measurement results for audits and inspections
  • Detailed analytics including RMS and peak acceleration (m/s²), frequency (Hz), grip strength (kg), and exposure duration

Hosted on Amazon Web Services, the system supports secure digital safety management and modern safety technologies.

Designed for Real Work Environments

HAV Sentry is built for daily use in demanding conditions involving heavy machinery, vibrating tools, and variable environments.

  • Soft, moisture-wicking materials allow comfortable long-term wear
  • Central control unit is IP64 dust and water resistant
  • Suitable for construction, manufacturing, utilities, and industrial settings

This ensures monitoring devices remain practical, reliable, and unobtrusive.

Why Choose HAV Sentry?

HAV Sentry helps organisations:

  • Accurately monitor hand-arm vibration exposure
  • Reduce the risk of HAVS and Vibration White Finger
  • Strengthen compliance with vibration regulations and regulatory standards
  • Protect workers from permanent health effects
  • Replace assumptions with evidence

It is not just a monitoring tool, it is a HAVS prevention and Risk Management system designed for modern occupational safety.
