Why did the Advertising Standards Authority have to rule on what should be common knowledge? What is HAVS monitoring best practice, what do insurers say and could zero monitoring be the best option? You would have thought that the issues surrounding wrist-mounted vibration monitors had already been thoroughly settled. Apparently not so in the minds of some. The following is an outline of some of the very costly myths associated with
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.
