Quick answer
Identify whether the work transmits vibration through the hands or through the body, assess actual exposure and reduce it at source. Use representative task information and competent help where necessary; a tool register or a training certificate alone does not establish safe exposure.
Why the task matters more than the tool list
HSE distinguishes hand-arm and whole-body vibration. Holding a powered tool or feeding material into vibrating equipment presents a different assessment problem from repeated jolts through a vehicle seat. Both can occur in one business, including maintenance and goods handling.
A list of tools does not show how people use them. Watch representative work, ask about longer or unusual jobs and include agency staff. An exposure assessment should reflect the equipment’s condition, the task and the time vibration actually reaches each worker.
Build an exposure record that supports a decision
For hand-arm exposure, HSE’s assessment guidance explains how to use suitable vibration data and actual contact or trigger time. Check that supplier figures represent your task; the time a tool is issued is not automatically its vibration exposure time. Combine relevant tasks rather than judging each tool separately.
| Assessment question | Useful workplace evidence | Decision it supports |
|---|---|---|
| What vibrates, and how? | Tool/process or vehicle, actual contact and work location | Choose the appropriate hand-arm or whole-body assessment |
| How much exposure occurs? | Representative data, actual use and variation between shifts | Compare with the applicable action and limit values using competent assessment |
| Can the source be changed? | Alternative process, equipment trial or route inspection | Remove or reduce exposure before relying on work rotation |
| Do controls work in practice? | Maintenance, observations, worker feedback and revised exposure evidence | Confirm improvement and identify further action |
Control tools and vehicles through different measures
For tools, consider eliminating the vibrating operation, selecting a suitable lower-vibration method and maintaining equipment and consumables. Plan work to reduce the remaining exposure, with instruction on the actual controls. Do not assume sharing the same hazardous task between more people removes the source.
HSE’s whole-body vibration guidance identifies shocks and jolts from mobile equipment as important. For example, a forklift driver reports repeated jolts on a broken yard route. Review the route, vehicle suitability, maintenance, seating and work method together; shortening a shift alone leaves the rough surface unchanged. Back symptoms can have several causes, so this example is not a diagnosis.
Act on reports and keep the national rules clear
Encourage early reporting of hand tingling, numbness or changes in finger colour and arrange appropriate occupational-health advice. Do not wait for a worker to prove a diagnosis before reviewing exposure. Establish health surveillance where the relevant duties and risk assessment require it.
In Northern Ireland use HSENI’s vibration guidance and the NI regulations. Keep assessment decisions, control owners and review triggers together. Revisit them when equipment, routes, workloads or health information change.

Can one safe time limit cover every vibrating tool?
No. Exposure depends on vibration magnitude, actual use and the combination of tasks. Use suitable assessment data and the applicable assessment method rather than a universal minutes-per-tool rule.
Next steps
Observe one representative task, check the exposure evidence and assign a person to remove or reduce its main vibration source. Arrange competent assessment where the evidence is insufficient.
