The Health and Safety Executive is investigating why a Belgian worker fell to his death in Wales last week.
The 45-year-old man, an employee of steelwork contractor Pierson Montage, was working at the Padeswood Works in Mold, north Wales, when he fell 9 m. He was understood to be in a harness.
Paul Corby, national officer at Amicus, said: “This kind of accident proves that our campaign to tighten up the EU Posted Workers' Directive must be upheld by the government. Amicus is campaigning for the government to make sure that foreign workers in Britain are employed on the same rates and conditions as British workers.”
He added: “This accident is typical of what happens when a foreign worker is employed in a strange environment.”
A second death in Wales occurred on 7 July when a self-employed man aged 53 fell 6 m through an asbestos roof at a service station in Pontardawe, Neath.
