The client on the project was also sentenced and asked to pay £75,000 for failing to supervise and monitor the demolition work adequately.
A Health and Safety Executive investigation found that Jose Luis Santos Canal, who worked for Spanish construction firm Porvi Construcciones y Contratas, was part of a demolition team dismantling redundant machinery at Befesa Salt Slags' plant in Fenns Bank, just inside the Welsh border near Wrexham, when the incident happened on 14 July 2015.
Canal was using flame cutting machinery to cut through the steelwork that supported a large metal hopper. The hopper collapsed and knocked him from the structure where he was standing. He was killed in the fall.
The investigation identified key failings that contributed to his death. The hopper was not supported before it was cut from the structure. Canal had no edge protection for working at height and was not wearing his harness.
During a further site inspection in October 2015, HSE inspectors found that Befesa Salt Slags had not reported several incidents at the site, and that two workers had been diagnosed with HAVS earlier in the year.
Porvi Construcciones y Contratas of Zamora, Near Valladollid, northern Spain, was convicted in absentia of breaching ss 2 and 3 of the Health and Safety at Work Act. The construction firm was fined a total of £3m and full costs.
At a hearing at Caernarfon Crown Court on 30 November, Befesa Salt Slags, which specialises in the recycling of steel dust, salt slags (a byproduct of aluminum recycling) and other aluminum residues, was fined a total of £225,000. It was also ordered to pay full costs of £67,092.
The firm, based at Fenns Bank, Whitchurch, pleaded guilty to breaching ss 2 and 3 of the Health and Safety at Work Act and reg 5(1) of the Reporting of Injuries, Diseases and Dangerous Occurrence (RIDDOR) Regulations 1995. It also admitted breaching reg 4(2) and two breaches of reg 8(d) of the 2013 RIDDOR regulations.
