Scarborough-based acoustic firm Castle Group has developed an instrument to measure the risk of Vibration White Finger (VWF), the painful condition caused by restricted blood supply following prolonged exposure to vibration.

The GA20001 Harm hand arm risk assessment meter will help companies meet HSE requirements for risk assessment under the Health & Safety at Work regulations, and is said to meet HSE guidelines on VWF.

Using piezoelectric technology, which converts mechanical strain into electrical signals, Harm produces a vibration measurement from acceleration readings taken along three axes, X, Y and Z.

The readings appear on the instrument screen and can be printed out or downloaded to a PC for record keeping.

The industrial injury claims from 30,000 Scottish miners said to be suffering from VWF illustrate the potential size of the problem, which can affect workers in other industries.

In the case of the miners, pneumatic drills are blamed for painful tingling in the fingers.
