Control of Vibration at Work Regulations

Regular use of vibrating equipment and vehicles can lead to debilitating health problems, such as back pain and carpal tunnel syndrome.

The Control of Vibration at Work Regulations (the Vibration Regulations) aim to protect workers from risks to health from vibration by making it a requirement for employers to assess and identify measures to eliminate or reduce risks from exposure to vibration. For this purpose, the regulations introduced an:

  • exposure action value of 2.5 m/s2 A(8), at which level employers should introduce technical and organisational measures to reduce exposure; and
  • exposure limit value of 5.0 m/s2 A(8), which should not be exceeded.

Employers must take action to prevent exposure to vibration and this should be done by considering whether there are other methods or machines that would eliminate the hazard, especially where large shocks and jolts are involved.

If this isn’t possible, the exposure should be reduced to as low a level as is reasonably practicable by:

  • introducing control measures whenever employees' daily exposure to vibration is likely to exceed the exposure action value; and
  • not exposing employees above the exposure limit value.

Some controls may take time to put in place, particularly where machines must be replaced or new ways of doing things have to be developed, and so an action plan that clearly states which managers, supervisors and employees are responsible for its delivery, what testing needs to be completed and when this all needs to be completed by is normally required.

Where the risks are low, the necessary controls may be simple and inexpensive, but where the risks are high, actions might need to be prioritised.

Where required, duty holders must ensure that:

  • control measures to reduce vibration are properly applied; and
  • information, training and health surveillance is provided for affected workers.

The surveillance programme should be set up so that vulnerable workers are monitored for certain early warning signs and symptoms as the earlier they get spotted, the better.

Symptoms of over-exposure to vibration include:

  • either pain or a lack of feeling in fingers and hands;
  • numbness and tingling in fingers;
  • an inability to sleep;
  • loss of strength in hands; and
  • fingers turning white then red (particularly in cold and damp weather).

Some workers experience these symptoms after exposure to vibration for just a matter of months while others might go on for years without any apparent issue. However long it takes for symptoms to emerge, if neglected, they can become permanent.

It’s essential that controls are reviewed if anything changes that may affect workers’ exposures to vibration so that they don’t exceed the action and limit values prescribed by the Vibration Regulations.
