TL;DR
A hand arm vibration toolbox talk explains that regular use of vibrating tools can permanently damage the nerves, blood vessels and joints in the hands, a condition called HAVS. Follow your site's tool time limits, keep tools maintained and hands warm, and report tingling, numbness or white fingers early.
This hand arm vibration toolbox talk is for anyone who regularly uses breakers, grinders, sanders, impact wrenches, hammer drills, chainsaws or strimmers. It takes about five minutes. The crew should leave knowing which tools carry the most risk, how to cut exposure, and which symptoms to report before the damage becomes permanent.
Why does hand arm vibration matter?
The UK's HSE is blunt about it: HAVS is preventable, but once the damage is done it is permanent. It describes the condition as serious and disabling, says nearly 2 million people are at risk, and notes that cold can trigger painful finger-blanching attacks.
HSE lists the common culprits as hand-held grinders, impact wrenches, hammer drills, concrete breakers, needle scalers, polishers, sanders, jigsaws, chainsaws and strimmers. Workers it quotes describe being unable to feel small screws, button up, or turn a newspaper page.
Under the UK's Control of Vibration at Work Regulations 2005, the daily exposure action value is 2.5 m/s² A(8) and the limit value is 5.0 m/s² A(8). Rules differ by country, so check the rules where you work.
Talking points for your hand arm vibration toolbox talk
- Know the high-vibration tools. Find out which tools on site vibrate the most and what their trigger-time limits are. Ask if you don't know.
- Watch the trigger time. Follow any daily limits your site sets, and break up long runs on one tool with other tasks.
- Maintain and sharpen. Worn bearings, unbalanced discs and blunt cutters all raise vibration. Report a tool that feels rougher than usual, and see our power tool safety talk for pre-use checks.
- Grip only as hard as you need. HSE advises against gripping or forcing a tool more than necessary, because a tighter grip passes more vibration into the hand.
- Keep hands warm and dry. Wear gloves in the cold, store tools so the handles aren't freezing, and massage and move your fingers during breaks. HSE also notes that smoking reduces blood flow.
- Report symptoms early. Tingling, numbness, clumsiness or white fingertips should go to your supervisor or health surveillance contact straight away.
Example to share with the crew
Picture this: a groundworker uses a breaker most mornings. Over a few months he notices his fingers tingle for an hour after work, and one cold morning two fingertips go white.
He puts it down to the weather and says nothing. Ask the crew what he should do. The answer is report it now, while tool changes and shorter exposure can still help, rather than wait for it to get worse.
Hand arm vibration checklist
- High-vibration tools on site are identified and labelled with time limits
- Lower-vibration tools or methods have been considered for the task
- Tools are maintained, discs balanced and cutters sharp
- Operators rotate tasks to limit continuous trigger time
- Gloves and warm, dry storage for tools are available in cold weather
- Workers know the early symptoms and who to report them to
- Health surveillance is in place for regularly exposed workers, where required
Questions to ask the crew
- Which tool do you use that leaves your hands tingling?
- Do you know the time limit for the most-used vibrating tool here?
- Is there a job we could do with less vibration, or with a different method?
How to close the talk
The one takeaway from this hand arm vibration toolbox talk: HAVS damage is permanent, so cut trigger time and report tingling or white fingers early. Tell your supervisor or the site's health surveillance contact, or log it through the usual reporting route.

Frequently asked questions
What should a hand arm vibration toolbox talk cover?
Cover what HAVS is, which tools on site vibrate most, any time limits for those tools, maintenance, keeping hands warm, and the early symptoms to report. Ask the crew which tool leaves their hands tingling.
What are the early signs of HAVS?
Tingling and numbness in the fingers, loss of feeling or grip, and fingers turning white in the cold are common signs. HSE says damage from HAVS is permanent once done, so early reporting matters.
What are the hand arm vibration exposure limits?
In the UK, the daily exposure action value is 2.5 m/s² A(8) and the exposure limit value is 5.0 m/s² A(8). Other countries set their own values, so check the rules where you work.
Do anti-vibration gloves stop HAVS?
Do not rely on gloves alone. HSE's advice to workers focuses on low-vibration tools, good maintenance, less time on the tool, and keeping hands warm and dry.
