The firm was prosecuted by the Health and Safety Executive (HSE) who conducted an investigation into the death of an employee of the company who fell through a roof while dismantling the disused hangar on 16 December 2006.

The employee fell approximately 30 feet onto the concrete floor below, and died at the scene from multiple internal injuries. He had previously cut through the PVC tarpaulin roof and as he went to climb back in to the mobile work platform, he fell through the section he had cut away.

Bristol Crown Court heard that there were no other protective measures in place and that the company should have ensured that the employee had no need to climb directly onto the roof.

The company pleaded guilty to breaching Section 2(1) of the Health and Safety at Work etc. Act 1974 and was fined £100,000. The company was also ordered to pay costs of £48,795.36.

Speaking after the hearing a HSE inspector said:

"The employee should have been properly protected by the company, instead he lost his life. The company failed in its duty to ensure there was a properly planned and supervised means of working - there should have been no need to work directly on the roof.

Falls from height can be extremely serious risks and adequate safety measures must be in place to protect all workers in order to prevent tragic incidents such as this."
