Father-of-one, Tony Causby, from Leigh, was working for Atherton- based S&S Scaffolding at the Walker Snack Foods site in Pennine Place, Skelmersdale, when the tragedy happened.
S&S Scaffolding pleaded guilty to single breaches of the Work at Height Regulations 2005 and the Health and Safety at Work etc Act 1974. The company, of Arley Way, was fined £75,000 and ordered to pay £31,517 in prosecution costs.
Mr Causby, 42, was helping to dismantle scaffolding when he stepped onto one of 80 fragile skylight and fell 12 metres to the concrete floor below on December 14, 2010.
He was pronounced dead at the scene.
Mr Causby’s partner, Debra Wyley, 44, said: “It is difficult to put into words how Tony’s death has affected our lives. I feel our son is missing out on so many things that his dad would have done with him, like football, rugby and taking him swimming.
“I miss Tony so much.
“He was such a big part of our lives and was very close to my family.”
Liverpool Crown Court heard that the accident occurred after employees went back to work after lunch when it is believed that Mr Causby walked in between the barrier scaffolding and the hand rail and stepped across the skylight as if to walk back towards the site where he was last working.
Giving his judgement on Wednesday last week, following a two- day hearing, Judge Graham Morrow, QC. said the company had fallen “significantly” below the requisite safety standard at the site in Skem.
He described their control measures as “inadequate and poor” and could have been re-visited once it was known that workers were to go onto the roof.
