This project focused on assessing whole-body vibration (WBV) exposure for warehouse vehicle operatives at a large distribution site in Swindon. The goal was to get a realistic understanding of how much vibration workers are exposed to during everyday tasks — mainly while operating pallet trucks, counterbalance vehicles, and VNA machines — and to check whether any of these activities could pose a long-term health risk.
The assessment was carried out during a typical working day, observing how vehicles were used, how long employees spent driving, and how smooth (or not) the working environment was. The good news is that all measured vibration levels fell comfortably below the legal action and limit values, which means employees are not currently at risk of excessive vibration exposure. Even the heaviest-used equipment — the ride-on pallet truck — stayed well within safe boundaries.
But vibration exposure isn’t just about average levels. Sudden jolts, shocks, and poor driving technique can add unnecessary strain to the body, especially the lower back. The review found that while the floor surfaces were generally smooth and the vehicles in good condition, drivers were often operating at the upper end of the vehicle’s capability. With no set speed limit in place, it’s easy for vibration to creep up without anyone noticing.
The assessment helped highlight practical improvements: maintaining tyres and suspension, ensuring seats are properly adjusted, keeping driving speeds consistent, and giving employees refresher training on best driving practices. Small behavioural changes can significantly cut the amount of jarring movement that reaches the body.
Overall, the site is performing well, and WBV levels are low. This assessment offers reassurance that current practices are keeping workers safe, while also giving the business a clear, simple roadmap for reducing vibration even further. With a few tweaks, the workplace can stay comfortable, compliant, and well-protected long into the future.
