Hand-arm vibration risk has traditionally been measured and managed using tool-based assessment methods, with ISO 5349 providing the recognised framework for evaluating exposure to hand-transmitted vibration.
But the way organisations manage HAVS risk is changing.
With more businesses looking for practical ways to monitor vibration exposure across real working environments, wearable HAVS monitoring devices are becoming a bigger part of the conversation. Instead of only asking what level of vibration a tool can produce, safety teams are increasingly asking a more useful question: what is each worker actually exposed to during the day?
That is where ISO/TS 22270 becomes important.
ISO/TS 22270 provides guidance for systems that monitor or measure hand-transmitted vibration using devices fitted to the hand, wrist or arm. It does not replace ISO 5349, and it does not make wearable monitoring a shortcut to compliance. Instead, it helps clarify how on-person monitoring systems can support a more practical, worker-focused approach to HAVS exposure management.
For employers, this matters because vibration risk is rarely static. Workers may use several tools across a shift, task durations can vary, and exposure can build up in ways that are difficult to capture through manual logs or occasional measurements alone.
In this article, we explain what ISO/TS 22270 is, how it relates to ISO 5349, and what it means for employers considering wearable HAVS monitoring as part of their vibration risk management strategy.
ISO/TS 22270 is a Technical Specification focused on the use of wearable systems for monitoring and measuring hand-transmitted vibration.
In simple terms, it gives guidance on systems that are fitted to the hand, wrist or arm to help assess vibration exposure. That makes it especially relevant to wearable HAVS monitoring devices, where the aim is to understand exposure at the worker level rather than relying only on tool data, estimates or manual time records.
The standard reflects a shift in how vibration exposure can be understood in real working environments. Traditional assessment methods are still important, but they often depend on knowing which tools are used, how long they are used for, and what vibration magnitude should be applied to each task. In busy workplaces, that information can be difficult to capture accurately every day.
Wearable monitoring can help close that gap by collecting exposure data closer to the person doing the work. This can make it easier to identify high-risk tasks, understand how exposure builds up across a shift, and spot patterns that may otherwise be missed.
However, ISO/TS 22270 should not be seen as a replacement for existing HAVS assessment methods. It is designed to sit alongside the established framework, helping organisations understand how wearable monitoring systems can be used appropriately, validated correctly and interpreted in context.
For employers, the key point is this: ISO/TS 22270 gives wearable HAVS monitoring a clearer place within vibration risk management. It does not remove the need for competent assessment or effective controls, but it does support a more practical and continuous approach to understanding exposure.
ISO 5349 remains the recognised foundation for measuring and evaluating exposure to hand-transmitted vibration. It sets out how vibration exposure should be assessed and is widely used as the reference point for HAVS risk management.
ISO/TS 22270 does not replace that framework. Instead, it supplements it by providing guidance for wearable or on-person monitoring systems fitted to the hand, wrist or arm.
That distinction matters.
ISO 5349 is primarily associated with measuring vibration from tools and equipment at the point where vibration enters the hand. This is essential for understanding the vibration magnitude of a tool and calculating a worker’s daily exposure.
ISO/TS 22270 looks at the same problem from a different angle. It recognises that modern monitoring systems can be worn by the worker and used to collect exposure data across real tasks, shifts and working patterns. This can help safety teams move beyond occasional measurements or manual estimates and gain a clearer view of how vibration exposure builds up in practice.
The two standards should therefore be seen as complementary. ISO 5349 provides the established basis for evaluating hand-arm vibration exposure. ISO/TS 22270 adds guidance for wearable monitoring systems that can support more continuous, person-based exposure management.
For employers, this means wearable HAVS monitoring should not be treated as a shortcut around existing standards. The better way to view it is as a practical tool that can help apply recognised vibration exposure principles more consistently across the workforce.
In other words, ISO 5349 remains the foundation. ISO/TS 22270 helps bring that foundation into more everyday, real-world monitoring.
In the UK, employers’ legal duties around hand-arm vibration are set out in the Control of Vibration at Work Regulations 2005. These regulations require employers to assess vibration risk, reduce exposure where reasonably practicable, provide information and training, and take action when exposure reaches certain levels.
This is where ISO 5349 and ISO/TS 22270 fit in.
The regulations set the legal framework, including the Exposure Action Value of 2.5 m/s² A(8) and the Exposure Limit Value of 5 m/s² A(8). ISO 5349 supports that framework by providing a recognised method for measuring and evaluating exposure to hand-transmitted vibration. In other words, the regulations explain what employers must manage, while ISO 5349 helps define how vibration exposure can be measured and assessed.
ISO/TS 22270 adds another layer by addressing wearable and on-person systems that monitor or measure hand-transmitted vibration. As these systems become more widely used, the Technical Specification helps clarify how wearable monitoring can sit alongside existing measurement methods and support day-to-day exposure management.
The important point is that neither ISO 5349 nor ISO/TS 22270 replaces the legal duties under the Control of Vibration at Work Regulations. A standard can support compliance, but it is not compliance by itself. Employers still need to use the data properly, reduce risk where possible, act when exposure is too high, and keep their HAVS management programme under review.
For safety teams, the relationship can be understood simply:
The Control of Vibration at Work Regulations define the legal duty. ISO 5349 provides the established measurement and evaluation framework. ISO/TS 22270 gives guidance for modern wearable systems that can help monitor exposure in real working conditions, while ISO 5349 remains the key reference point for formal measurement and evaluation methods used in regulatory contexts.
Together, they point towards a more practical approach to HAVS management: understand exposure using recognised principles, monitor risk more consistently, and use the results to take action before long-term harm occurs.
Tool-based measurement remains a part of HAVS risk management. It can help employers understand the vibration magnitude of specific tools and calculate likely exposure based on how long those tools are used.
The challenge is that real working days are rarely that neat.
A worker might use several tools across one shift. One task may take longer than expected. Another may be completed in short bursts. Tool condition, accessory choice, material, grip force and working method can all affect the level of vibration exposure. Relying only on estimated trigger times or paper-based records can leave gaps between what is planned and what actually happens on site.
Wearable HAVS monitoring helps address that gap by focusing on the person, not just the tool.
Instead of only asking how much vibration a tool can produce, wearable monitoring helps show how exposure builds up for the individual worker during the day. This can make it easier to identify high-risk tasks, spot repeated exposure patterns, and understand where control measures may need to be improved.
That person-based view is one of the reasons ISO/TS 22270 is important. It recognises that wearable systems can play a role in practical exposure monitoring, provided they are used appropriately and interpreted in context.
For safety teams, this can make HAVS management more proactive. Rather than waiting for manual records, periodic assessments or health surveillance outcomes to reveal a problem, wearable monitoring can help identify exposure risks earlier and support more informed decisions about tool use, task planning and worker rotation.
For many years, wearable HAVS monitoring has sat in a slightly awkward space. The technology offered a practical way to understand exposure in real working conditions, but the recognised standards were largely built around more traditional tool-based measurement methods.
ISO/TS 22270 helps change that.
By creating specific guidance for systems fitted to the hand, wrist or arm, the standard recognises that wearable monitoring is no longer just an emerging idea or a convenient add-on. It is now part of the wider conversation around how hand-arm vibration exposure can be monitored, measured and managed in modern workplaces.
That matters because HAVS risk is difficult to manage using estimates alone. Employers may know which tools are used and what those tools are capable of producing, but they often have less visibility over how exposure builds up across different workers, tasks and shifts. Wearable devices help address that by making exposure monitoring more continuous, personal and practical.
ISO/TS 22270 does not mean every wearable device should automatically be trusted. It also does not mean wearable monitoring replaces competent assessment or recognised measurement methods. What it does do is give employers a clearer framework for asking the right questions about wearable systems: how they work, how they have been validated, what they measure and how their data should be interpreted.
In that sense, the development helps legitimise wearable HAVS monitoring as a modern solution to a long-standing problem. It acknowledges that safety teams need more than occasional snapshots and manual records. They need practical, worker-level data that helps them understand exposure as it happens and take action before risk becomes harm.
For employers, the message is not that wearable devices are a shortcut to compliance. The message is that, when used properly, they can be a credible and scalable way to strengthen HAVS risk management.
As wearable HAVS monitoring becomes more widely recognised, employers will need to look beyond whether a device simply claims to measure vibration. The more important question is whether the system provides useful, reliable data that can support better risk management decisions.
A good wearable HAVS monitoring system should be clear about what it measures, how exposure is calculated and where its limitations are. No monitoring system is suitable for every task, tool or working environment, so transparency matters. Employers should be able to understand how the device is intended to be used and what the data can reasonably tell them.
It should also present exposure in a format that safety teams can act on. For HAVS management, that means reporting daily exposure in a way that aligns with recognised principles, such as A(8) values or exposure points. This helps employers understand when workers are approaching the Exposure Action Value or Exposure Limit Value, and where changes may be needed.
Practicality is just as important as technical capability. If a system is difficult to use, relies heavily on manual input or creates extra admin for supervisors, it is less likely to be used consistently. The best systems make monitoring easier, not harder, by giving teams clear dashboards, alerts, reports and worker-level exposure records.
Employers should also consider how the system has been validated. Wearable monitoring should be benchmarked against recognised reference methods where appropriate, with clear evidence of performance and accuracy. This does not mean the device replaces specialist vibration testing, but it does mean employers can have more confidence in the data it provides.
Ultimately, a wearable HAVS monitoring device should not just collect numbers. It should help safety teams identify risk, prioritise controls and show that vibration exposure is being actively managed.
Wearable HAVS monitoring does not create compliance on its own, but it can make compliance easier to manage and evidence.
Under the Control of Vibration at Work Regulations, employers need to assess vibration risk, reduce exposure where reasonably practicable, and take action when workers are likely to reach the Exposure Action Value or Exposure Limit Value. In practice, that means employers need reliable information about who is exposed, how often, and to what level.
That is where wearable monitoring can help.
Instead of relying only on manual time sheets, estimated trigger times or occasional tool measurements, wearable systems can provide more regular visibility of worker-level exposure. This can help safety teams identify when exposure is building up, which tasks are creating the most risk, and whether control measures are actually working.
This is particularly useful in workplaces where tool use varies from day to day. A worker may be below the limit on paper, but their real exposure could be higher if tasks overrun, tools are used differently, or manual records are incomplete. Wearable monitoring gives employers a clearer view of what is happening in practice.
It can also improve record-keeping. Exposure reports, alerts and trend data can help show that vibration risk is being actively monitored and reviewed. That matters during internal audits, health and safety inspections, incident investigations or claims, where employers may need to demonstrate that they took reasonable steps to manage the risk.
The important caveat is that data must lead to action. If monitoring shows repeated high exposure, employers should review the task, reduce trigger time, rotate workers, maintain or replace tools, improve working methods, or seek specialist advice where needed.
Used properly, wearable monitoring supports compliance because it turns HAVS management from a periodic paperwork exercise into an ongoing risk management process.
spacebands is designed to make HAVS exposure monitoring easier to manage across real working environments.
Rather than relying only on manual logs, estimates or occasional checks, spacebands helps employers monitor worker-level vibration exposure across the day. This gives safety teams clearer visibility of how exposure builds up across different tasks, tools and shifts, making it easier to identify risk earlier and take action before exposure becomes a long-term health issue.
spacebands converts exposure measurement into daily A(8) values, helping employers understand how worker exposure compares against recognised HAVS thresholds. The system can also warn workers in real time when they reach key exposure levels, including the Exposure Action Value and Exposure Limit Value. This means exposure data is not just stored for later review. It can be used during the working day to help prevent workers from unknowingly continuing beyond safe exposure levels.
The system supports a more practical approach to HAVS management by giving employers access to exposure data, reports and alerts that can be used to review working practices, improve controls and maintain clearer records. For teams managing multiple workers, locations or tool types, this can reduce admin and make vibration risk easier to track consistently.
This is where the direction of ISO/TS 22270 is particularly relevant. The standard recognises the role that wearable systems can play in monitoring hand-transmitted vibration, while still making it clear that these systems need to be used appropriately and interpreted in context.
spacebands should not be seen as a replacement for specialist vibration testing where that is required. Instead, it gives employers a scalable way to monitor day-to-day exposure risk and strengthen their wider HAVS management programme.
In simple terms, specialist testing can help you understand the vibration characteristics of a tool. Wearable monitoring helps you understand how exposure is affecting workers in practice. Both have a role, but for day-to-day risk visibility, wearable devices offer a more practical way to keep HAVS exposure on the radar.
