HSE launches vibration calculator

The calculator compares workers’ exposures to the levels specified in the Control of Vibration at Work Regs, as part of a HAVS risk assessment.

Aimed at employers of workers who frequently and regularly use tools or machinery, such as hand-held power tools, hand-guided powered equipment or powered machines which process hand-held materials, the calculator will estimate: 

· partial exposure (shown in both m/s2 A(8) and exposure points) for each tool or process, as calculated from the vibration magnitude and the exposure duration

· daily exposure, also in m/s2 A(8) and exposure points, as calculated from the partial exposures.

The calculator includes a drop-down menu of vibration magnitudes for common tools from the HSE’s HAVS database that can be used to make cautious estimates of exposure.

The HSE guidance book L140 Hand-arm vibration has also been simplified and streamlined to provide clear information that will enable employers to make sensible and proportionate decisions about managing risks arising from hand-arm vibration. However, the HSE points out that the underlying message has not changed.
