Hand-arm vibration (HAVS) assessment (Health surveillance for hand-arm vibration syndrome)
A staged set of checks an employer arranges for workers who use vibrating tools, to catch early signs of hand-arm vibration syndrome — numb or whitening fingers, tingling and loss of grip — before damage becomes permanent.

In short
- HAVS is damage from vibrating tools — numb or whitening fingers, tingling, and loss of grip — and it is largely preventable.
- Established HAVS is usually permanent, so the whole point of surveillance is to catch it early and stop it getting worse.
- It uses a staged system: a questionnaire first, then a fuller assessment by occupational health, and a doctor if needed.
- Reporting symptoms early and the employer reducing vibration matter far more than the check itself — surveillance is a safety net, not a cure.
A plain-English summary. The detail — including risks and recovery — is below.

You move up the staged system to a fuller assessment, and to a doctor if HAVS is suspected.
The clinician stages the condition and advises on fitness for vibrating-tool work and on reducing exposure.
Your employer may be advised to lower your vibration exposure, change tools or alter tasks.
What is a hand-arm vibration (HAVS) assessment?
Hand-arm vibration syndrome (HAVS) is damage to the blood vessels, nerves and sometimes joints of the hands and arms, caused by regularly using vibrating tools such as grinders, drills, sanders, chainsaws, breakers and impact wrenches. Early signs include tingling and numbness in the fingers, fingers turning white (often in the cold — 'vibration white finger'), and loss of grip strength and dexterity. It can make everyday tasks like doing up buttons difficult.
HAVS surveillance is a staged ('tiered') set of checks your employer must arrange when vibration exposure is high enough. Under the Control of Vibration at Work Regulations, any worker exposed above the daily exposure action value (2.5 m/s² A(8)) is entitled to health surveillance, and there is also an exposure limit value (5 m/s² A(8)) that must not be exceeded.
The aim is to catch HAVS early. Early damage can stabilise or partly recover if vibration exposure is reduced, but established HAVS is usually permanent — there is no cure that reverses it. That is why reporting symptoms early, and the employer controlling vibration, matter so much.
The assessment does not, by itself, treat HAVS or guarantee you will not develop it. It is a way of detecting harm early and checking whether the employer's vibration controls are working.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Two parts of the HAVS picture (commonly used staging)
| Component | What it affects | Typical early signs |
|---|---|---|
| Vascular (blood vessels) | Circulation to the fingers | Fingers turning white, often in the cold |
| Sensorineural (nerves) | Feeling and dexterity | Tingling, numbness, clumsiness |
| Both can worsen | Hands and fingers | More frequent attacks, wider areas affected |
Clinicians often grade HAVS by stage. Established damage is usually permanent, so early detection and reduced exposure are key.
Preparing for your test
- Note any symptoms in your fingers or hands — tingling, numbness, whitening, loss of grip or dexterity — and when they happen (for example in the cold).
- Think about how often, and for how long, you use vibrating tools, and which ones.
- Avoid heavy use of vibrating tools just before a fuller assessment if asked, as recent use can affect findings.
- Tell the assessor about other causes of similar symptoms (for example circulation problems, smoking, some medicines, carpal tunnel syndrome).
- Bring details of previous HAVS questionnaires or assessments if you have them.
- Understand what will be shared with your employer (fitness advice only) and what stays confidential.
What happens
The staged system usually begins with a questionnaire — when you start vibrating-tool work and then each year — asking about finger and hand symptoms. This is often handled by a trained responsible person, with occupational health oversight.
If you report symptoms, you move to a fuller assessment by a qualified occupational health nurse or technician, who takes a detailed history of your symptoms and tool use and examines your hands. If HAVS is suspected, an occupational health doctor assesses you, can make a formal diagnosis, and stages how advanced it is. Sometimes additional standardised tests of nerve and blood-vessel function are used.
The clinician considers other possible causes of similar symptoms, because not all tingling or white fingers are due to vibration. They then advise on whether you are fit to continue vibrating-tool work, whether adjustments are needed, and whether exposure must be reduced. Your employer is told the fitness outcome, not the clinical detail, and you can see your own report.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- A questionnaire alone cannot diagnose HAVS — diagnosis and staging need a fuller assessment, ultimately by an occupational health physician.
- It is not the right route for an acutely painful, cold, white finger that does not recover, which needs prompt medical assessment.
- It cannot reverse HAVS that has already developed; its role is detection and prevention of worsening.
- It is not a general check for all hand or wrist problems — conditions like carpal tunnel syndrome may need separate assessment.
Delay or rearrange if…
- You have just finished heavy vibrating-tool use and have been asked to avoid it before a fuller assessment.
- You have not been told what will be shared with your employer or have unresolved consent concerns.
- An acute hand problem needs medical attention first.
- You are between roles such that exposure questions would not reflect your actual job.
Alternatives to discuss
- Reducing vibration at source — lower-vibration tools, limiting trigger time, job rotation, maintenance.
- Keeping hands warm and maintaining circulation to reduce attacks.
- GP or specialist assessment where another condition (such as carpal tunnel syndrome or a circulation disorder) is suspected.
- Redeployment to non-vibrating work where exposure cannot be safely controlled.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Can detect HAVS early, before damage becomes severe or permanent
- Allows exposure to be reduced in time to stop the condition worsening
- Checks whether the employer's vibration controls are actually working
- Helps distinguish HAVS from other causes of similar hand symptoms
- Can support adjustments or a change of task to protect your hands
- Protects colleagues using the same tools
Risks & complications
- Time taken for questionnaires and assessments
- Anxiety about whether symptoms will affect your job
- Findings that need further assessment or referral
- Symptoms that turn out to have a different cause and need other care
- A diagnosis of HAVS that may restrict the vibrating-tool work you can do
- False reassurance if questionnaires are not acted on or assessments are superficial
- Concern about who sees information, if confidentiality is not explained
- Advanced HAVS that significantly affects hand function and daily life
- A confirmed case that must be reported to the enforcing authority
Established HAVS does not get better, so the real risk is missing it early or carrying on with high exposure after symptoms start. Surveillance only helps if symptoms are reported promptly and the employer reduces vibration. Ask what your daily vibration exposure is compared with the action and limit values, what the employer is doing to lower it, and what your result means for your work.
Published figures to discuss
The chance of developing HAVS depends strongly on how much vibration a worker is exposed to and for how long, as well as individual susceptibility, so a single percentage would be misleading. Higher and longer exposure increases risk. Because the condition develops gradually and varies between people, we describe risk qualitatively rather than quoting a rate, and emphasise that established HAVS is generally permanent.

|---|---|---|---|
| HAVS progression | Exposure-dependent | Risk rises with vibration dose, duration, cold exposure and continued use of vibrating tools. | HSE — Hand-arm vibration at workhse.gov.ukSource-linked context |
| Irreversible symptoms | Recognised once vascular or nerve damage is established | Early reporting matters because late HAVS may not fully recover after exposure stops. | HSE — Hand-arm vibration at workhse.gov.ukSource-linked context |
| False-negative early assessment | Recognised | Symptoms can be intermittent; surveillance depends on honest reporting and appropriate follow-up. | Guide sourcesClinical context |
| Control failure at workplace level | Common practical risk | Health surveillance is not a substitute for reducing vibration exposure under HSE controls. | HSE — Hand-arm vibration at workhse.gov.ukSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no recovery from the assessment itself. What matters afterwards is what any finding means for your hands and your work, and the action taken to reduce vibration.
- Carrying on with work after a questionnaire or assessment
- Being asked detailed questions about finger and hand symptoms and tool use
- Moving to a fuller assessment only if symptoms are reported
- Being told fitness advice, with detail kept confidential
- Annual repeat checks
Aftercare
- Report any new or worsening finger or hand symptoms promptly, not just at the annual check.
- Follow advice on reducing tool use, keeping hands warm and maintaining circulation.
- Use anti-vibration measures and well-maintained tools as provided.
- Attend any further assessment or referral arranged.
- Follow up non-work causes of hand symptoms with your GP.
- Note when your next check is due.
- Ask how to see your own report and correct any factual error.
- Note of finger and hand symptoms and when they occur
- Details of which vibrating tools you use and for how long
- Note of other possible causes (smoking, circulation problems, medicines)
- Any previous HAVS questionnaires or assessments
- Understanding of what is shared with your employer
- Date of your next scheduled check

Results & realistic expectations
A clear questionnaire and assessment, with no symptoms, suggests you do not currently have detectable HAVS and that your hands are coping with the exposure. A diagnosis is staged to show how advanced any damage is.
Results must be read in context. A normal check is reassuring but reflects one point in time and looks specifically for vibration-related damage, so it cannot promise you will never develop HAVS if exposure continues. A diagnosis of HAVS does not necessarily stop you working, but it usually means exposure must be reduced, because established damage will not reverse. The most useful information comes from tracking your symptoms and findings year on year.
Each assessment reflects your hands on the day, which is why HAVS surveillance is repeated annually. HAVS that has developed is generally permanent, so the long-term value of surveillance is catching change early and keeping exposure low. Health records are kept for many years so progression can be tracked over a working life.
Related tests, treatments or support
HAVS surveillance usually forms part of a wider occupational health surveillance programme and sits alongside the employer's vibration risk assessment and control measures (lower-vibration tools, limiting trigger time, maintenance, keeping hands warm). Workers exposed to several hazards may also have respiratory, skin or hearing surveillance. Where symptoms could be due to another condition, referral for further tests may be arranged.
Follow-up & long-term care
If symptoms are reported or HAVS is suspected, you progress through the staged assessment and, where needed, to formal diagnosis and onward referral. The occupational health professional also reviews patterns across similarly exposed workers to advise whether the employer needs to reduce vibration further. Annual surveillance then continues.
- Attend each annual HAVS check.
- Report finger and hand symptoms promptly between checks.
- Keep hands warm and maintain good circulation at work.
- Use well-maintained, lower-vibration tools and limit trigger time as advised.
- Tell occupational health if your tool use or tasks change.
Repeat, follow-on and what comes next
- A positive questionnaire leads to a fuller assessment rather than an immediate diagnosis.
- Surveillance is repeated annually by design, so a clear check is a snapshot, not a guarantee.
- If HAVS is diagnosed, the focus shifts to reducing exposure and adjusting work, because the damage will not reverse.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- Clear advice on reducing tool use, keeping hands warm and using lower-vibration equipment.
- Prompt progression to fuller assessment and diagnosis when symptoms are reported.
- Confidential access to your own report and a route to correct factual errors.
- Group-level feedback that drives real reductions in vibration exposure.
- A reliable system so annual checks are not missed.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Which tiers of assessment are included (questionnaire only versus full assessment and formal diagnosis).
- Whether checks are done on-site or at an occupational health clinic.
- The level of occupational health professional involvement, including a physician for diagnosis.
- Any additional standardised tests of nerve and blood-vessel function.
- Reporting, record-keeping and group-level analysis.
- Onward referral when another cause of symptoms is suspected.
- Which tiers of assessment are included and who carries them out.
- Whether an occupational health physician is available for diagnosis and staging.
- How individual confidentiality and consent are handled.
- What is reported to the employer and what the worker receives.
- What happens if symptoms are found or further assessment is needed.
- How onward referral is arranged when another cause is suspected.
On the NHS? HAVS surveillance is arranged and paid for by your employer as part of their legal duties; investigation or treatment of hand symptoms may also be provided through your GP or the NHS.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not being told that only fitness advice, not clinical detail, goes to the employer.
- Treating a questionnaire as a diagnosis, or skipping the assessment when symptoms are reported.
- Assuming a clear check means continued high exposure is safe.
- Not knowing you can see your own report and correct factual errors.
- Surveillance used instead of reducing vibration exposure.
Marketing red flags
- HAVS surveillance promoted as 'guaranteeing' workers will not develop the condition.
- Questionnaire-only programmes with no route to assessment or formal diagnosis.
- No mention of vibration exposure values or the employer's duty to reduce them.
- Vagueness about confidentiality and who sees the results.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- What is my daily vibration exposure compared with the action and limit values?
- What is the employer doing to reduce vibration at source, not just monitor me?
- If HAVS is found, how will it affect the work I can do?
- Could my symptoms have another cause, and how will that be checked?
- How often will I be assessed, and what should I report between checks?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
