Misunderstanding Hand Arm Vibration monitoring marketing material can put hands and safety policies at risk. Caveat emptor. Stop Press: 27/02/17: HSE has just issued new guidance on HAV measurement and management covering similar concerns. These may well change the way you measure and monitor HAV risk – dramatically… A one-day HAV Master Class and competency update workshop covering these topics is now available.

Whole Body Vibration assessment and control
We provide a comprehensive Whole Body Vibration (WBV) assessment service against the requirements of the regulations. This can also be extended to include design and development work plus engineering recommendations to reduce the levels of vibration. We can also provide WBV assessment and management training up to full competency level.
Past Whole Body Vibration measurement projects under the Control of Vibration at Work Regulations include:-
- fork lift truck driver vibration
- staff exposure on ships – Merchant Shipping and Fishing Vessels (Control of Vibration at Work) Regulations 2007
- train driver vibration – London Underground tube lines
- large industrial plant
- construction plant
- truck drivers
- off-road vehicles
- high speed ribs…
Whole Body Vibration and Back Pain
The evidence of a link between the Action Values, back pain and Whole Body Vibration is poor under most circumstances – WBV comes a long way down the list of likely causes. The following is the hierarchy for investigation of potential issues:-
- poor design/adjustment of seating or controls
- poor driver posture and long periods in the seat
- manual handling and awkward access/jumping down from cab
- WBV – especially jolts and shocks
- non-occupational causes
In practice, the more serious potential vibration issues only tend to arise for off-road vehicles, high speed boats (e.g. ribs), some helicopters and a few other high vibration activities.
The standards involved are ISO 2631 (parts 1 and 2); BS 6841 (similar to ISO2631 part 1); BS 6472 (equivalent to ISO2631 part 2) – this also recommends vibration dose values (VDV) for impulsive vibration rather than weighted acceleration.
