Codes of Practice

This Guide provides information on how to manage risks associated with vibrating machinery in the workplace, and in particular whole-body vibration. A summary is available in the information sheet on Whole-Body Vibration.

What is whole-body vibration?
Whole-body vibration (WBV) is vibration transmitted to the whole body by the surface supporting it, for example through a seat or the floor. It is commonly experienced by drivers, operators and passengers in mobile plant when travelling over uneven surfaces. WBV may also be experienced while standing, for example standing on platforms attached to concrete crushing plant. WBV includes sharp impacts like shocks and jolts. Exposure to WBV mainly occurs in vehicles used off-road or on un-sealed roads, for example
on farms and construction, mine and quarry sites. It can also occur in other places like in small, fast boats and in helicopters. Most people who drive vehicles on surfaced roads in good repair are not likely to experience harmful levels of WBV. When road-going vehicles are used off road this activity may result in
higher levels of vibration.
