The company pleaded guilty to breaching Section 3(1) of the Health and Safety at Work etc. Act 1974 for its role in the incident at the construction site in central Nottingham. The company was fined £20,000 and ordered to pay £6,900 costs.

The court heard how on 30 August 2007 a contractor on the site drove a cherry picker over a concealed man hole cover.

The cover gave way under the weight of the machine and the cherry picker toppled over, leaving its driver with serious injuries to his skull, back and legs.

The long reaching arm of the machine crashed to the ground, landing in a busy area that had been occupied by pedestrians and vehicles only seconds before. Following the incident, Milton Street in central Nottingham was blocked off for almost six hours.

An inspector from the HSE commented after the case:

"This was a very dangerous incident, in an area which was bustling with pedestrians and vehicles. It could so easily have led to people being killed and has left a worker with serious injuries.

The company failed to put in place adequate measures to find and record where the man holes and service covers were around the site and failed to take steps to protect them or prevent vehicles from driving over them.

Operators of mobile elevating work platforms, such as scissor lifts and cherry pickers, must be warned about man hole covers and underground services because there is a real risk of them collapsing and heavy vehicles toppling over.

When people's lives are at risk it is absolutely inexcusable to leave this to chance."
