The victim was helping Bespoke Bodies employees clean valley gutters at the company's Warrington site in Cheshire, Liverpool Magistrates' Court was told. On 14 April 2016 he stepped back onto a fragile skylight and fell 9.1 m onto a table, sustaining three fractured ribs and a ruptured spleen.
The company had failed to identify the risks associated with working at height on fragile surfaces and had not properly supervised the job, the Health and Safety Executive said.
Bespoke Bodies pleaded guilty to breaching reg 3(1)(a) of the Management of Health and Safety at Work Regulations for failing to risk assess the gutter cleaning task, and s 2(1) of the Health and Safety at Work Act.
It was fined £20,000 plus an additional £3,340 in costs.
