New HSE HAVS calculator to help control risk

New calculator includes “cautious estimates” for common tools

The HSE Hand-Arm Vibration exposure calculator helps estimate and record worker exposure to such vibration and compare the exposures with the actions values in the regulations as part of a hand-arm vibration risk assessment.

The calculator has been updated and is available on the HSE website. The updated version includes a drop down menu of vibration magnitudes for common tools.

The data is taken from the HSE database of typical values which can be used to make “cautious estimates” of exposure before representative in-use data for specific tools is available.

Reinforced emphasis on risk control and management

The HSE guidance book L140, Hand-arm vibration, has also been revised.

The new edition has been updated in keeping with changes to related legislation, technical advances and experience.

The emphasis is on the control and management of risks from exposure to hand-arm vibration (HAV).

HSE stress that the policy on the control of HAV has not changed.

Vibration is a hazard for employees in many industries and occupations. Regular and frequent exposure can lead to hand-arm vibration syndrome (HAVS) and carpal tunnel syndrome (CTS).

HAVS is a permanent disease, causing disability which can progress with continued exposure. HAVS and vibration-induced CTS together account for two thirds of the ill-health cases reported through RIDDOR.
