This guide is for persons conducting a business or undertaking (PCBUs) that carry out work involving machines. It explains how to identify and manage the risks from excessive whole body vibration (WBV).

WBV occurs when vibration (including bumps, shocks and jolts) passes through someone’s body from the surface they are sitting or standing on.

Workers can be exposed to WBV if they regularly drive, ride in, or operate machines that travel over rough surfaces or have a vibrating function. Examples include tractors and mobile machinery like earth movers and bulldozers

Long term exposure to excessive WBV could harm workers.

As a PCBU, you must ensure, so far as is reasonably practicable, the health and safety of workers, and that other persons are not put at risk by your work. You must manage the health and safety risks to workers and others that arise from being exposed to the work carried out by your business.
