Symptomology
The clearest sign of hand-arm vibration syndrome (HAVS), sometimes called vibration white finger (VWF), is blanching of the fingers caused by spasms of the blood vessels that serve them, leading to pallor. Such spasms may involve all or part of one, several, or even every finger, which then become cold and numb, with reduced sensation. Episodes may persist for a few minutes or continue for a couple of hours. It is also possible for similar attacks to arise in the feet or the nose. There is no curative treatment, though spontaneous improvement may occur over time. The condition may occur naturally, yet it is frequently associated with over-exposure to vibrating tools. Its aetiology has not always been understood and, crucially for litigation in these cases, the courts have limited liability to periods after which employers ought reasonably to have been aware of the risks of HAVS and
