Negligence – Duty to take care. The defendant employer had breached its duty of care by failing sufficiently to risk assess the task of cleaning and tipping a tipper truck trailer, and also by failing to implement and enforce safe systems of work in respect of those tasks. Accordingly, the Queen's Bench Division allowed the claimant's claim arising from his injury when cleaning out the trailer within the vicinity of high voltage overhead power lines, but reduced damages by 25% to take account of the claimant's contributory negligence.
