AN industrial cleaning firm has been fined £35,000 and ordered to pay £120,000 in costs over the death of one of its workers who fell into a water-cooling tank at a power plant.

Michael Benn, 37, was part of a team of three from Epsco Ltd, working at Connah’s Quay power station on August 30, 2007, when the accident happened.

Mr Benn, from Fife, Scotland, was working as a team leader with Frazer Duff and Shane McNicoll using a hose and pump to clear away sludge and silt.

He feared the pump wasn’t working properly and went to investigate, but fell into a tank or sump and drowned in about two meters of water at the E.ON power station.
