Johnson Scaffold Services admitted breaching health and safety laws at Staines Magistrates’ Court today following the collapse on December 18 2009.
The court heard how Johnson erected sheeted scaffolding around a building in Copenhagen Way, Surrey, to enable a separate contractor to refurbish the roof.
Once the work was completed, the structure was partially removed the day before leaving some of the sheeted scaffolding still standing.
During the early hours of the following morning, a 200 foot long, 40 foot high section of the scaffolding was blown to the ground.
The HSE investigation showed the scaffolding was not installed according to the original drawings and had not been adequately tied. It was left in an unsafe condition overnight while being dismantled.
Johnson was fined £7,500 and ordered to pay costs of £7,000.
After the hearing, HSE’s inspector Denis Bodger said: “This was a serious incident that could have resulted in severe injury or worse, it was sheer luck that meant no one was in the way of the scaffolding when it collapsed.
“Scaffolds should be designed by a competent person or built to a recognised standard. At no stage during erection, use or removal should they be left in an unstable state where they could collapse. They should be adequately tied or other effective means taken.
”This should serve as a warning to other companies that HSE will not hesitate to take action against anyone that fails to build safe scaffolding.”
