If you work with vibrating tools or vehicles regularly — using a drill, grinder or chainsaw, or driving a fork truck — you may be at risk of long-term damage to your hands, arms and whole body. Many workers don’t realise that sustained exposure to vibration is a recognised health hazard, capable of causing back pain, carpal tunnel syndrome and vascular disorders. The damage builds slowly and is often permanent once established, which is exactly why it’s worth understanding — and controlling — early.
The industries most at risk include construction, farming, forestry, transportation and shipping. Vibration exposure falls into two distinct types, with different sources and different effects on the body.
The two types of vibration
Hand-arm vibration (HAV)
Damages the hands and arms, caused by gripping power tools — chippers, grinders, screwdrivers, drills — or vehicle controls. Over time it changes muscles, bones, joints and tendons, and can damage the nervous system.
Symptoms: reduced sensation and grip strength, tingling, loss of light touch, and blanching of the fingers (“vibration white finger”); carpal tunnel syndrome. Often worse in the cold.
Whole-body vibration (WBV)
Affects the whole body, caused by sitting in a vibrating vehicle or standing on a vibrating floor — driving a fork truck or off-road vehicle, or working near a power press or shakeout equipment.
Symptoms: back pain (sometimes severe), plus insomnia, fatigue, stomach problems, headaches and a general “shakiness”. Studies of professional drivers link it to muscular, back and circulatory disorders.
How much vibration is dangerous?
At low enough levels, a worker can be exposed for an entire career without harm. Two factors decide the risk: the intensity of the vibration (its magnitude), and the duration of exposure — a tool used briefly once a week is very different from one used all day, every day. Individual sensitivity varies too. The key is that both magnitude and time are measurable, and the law sets numbers around them.
The law: there ARE legal limits
Contrary to a common belief, vibration exposure is legally regulated in the UK. The Control of Vibration at Work Regulations 2005 set binding exposure values, measured as a daily A(8) figure (vibration averaged over an eight-hour day):
Exposure action & limit values
EAV = the level at which employers must act to control exposure. ELV = the daily maximum that must not be exceeded.
Hand-arm vibration
Whole-body vibration
Above the action value, employers must put in place technical and organisational measures to reduce exposure and provide health surveillance. The limit value must not be exceeded on any day. The regulations also require employers to assess the risk, control it, and monitor workers’ health — so HAVS is both a recognised, diagnosable industrial disease and one your employer has a legal duty to guard against.
How to reduce the risk
Choose low-vibration tools. Tool size, weight, handle position and drive mechanism all affect hand-arm exposure — ergonomic designs can reduce it significantly.
Isolate the source. A suspension system between the worker and a vibrating surface helps cut whole-body vibration.
Rotate jobs and build in rest. Supervisors should rotate positions and schedule breaks so no one is exposed continuously all day.
Train your team. Health and safety training teaches workers about vibration risk, tool maintenance, and gripping tools as lightly as is safe.
Report symptoms early. Encourage workers to flag early signs — caught and monitored early, the chronic effects can be dramatically reduced.
Frequently asked questions
Are there legal limits on vibration exposure?
Yes. The Control of Vibration at Work Regulations 2005 set an Exposure Action Value and an Exposure Limit Value for both hand-arm and whole-body vibration. Above the action value employers must control exposure and provide health surveillance; the limit value must not be exceeded.
What is the exposure limit for hand-arm vibration?
The hand-arm Exposure Limit Value is 5.0 m/s² A(8), with an Exposure Action Value of 2.5 m/s² A(8). For whole-body vibration the figures are 1.15 m/s² A(8) (limit) and 0.5 m/s² A(8) (action).
Can HAVS be diagnosed?
Yes. Hand-arm vibration syndrome is a recognised industrial disease, identified through health surveillance and clinical assessment. Because nerve and blood-vessel damage doesn’t fully reverse once established, early detection matters — which is why health surveillance is a legal requirement above the action value.
Whose responsibility is it to control vibration?
The employer’s. Under the regulations they must assess the risk, reduce exposure, provide suitable equipment and training, and carry out health surveillance. Workers should follow safe practices and report symptoms early.
