Michael Healy, 49, an electrical installation supervisor at the plant, died at the burns treatment unit at Cork University Hospital, exactly one week after the accident. A third staff member, caught in the blast, remains in a stable condition at the hospital.
Meanwhile, an industrial accident in Cork yesterday claimed the life of a worker aged in his 30s. The man, who was not named last night, was the seventh construction worker to die in Ireland this year.
The victim, from Cork city, became entangled in a rock-breaking machine shortly before noon in Cobh while he was working on clearing a site for McInerney Construction.
Gardaí said there were no witnesses to the incident but they ruled out foul play. The Health and Safety Authority is to conduct an inquiry at the Newtown site.
John Stanley, a spokesman for McInerney Construction, expressed the company’s sincere sympathy to the man’s family. “We were shocked to learn of his death. He was an employee of a specialist rock-breaking company working as a sub-contractor on the site,” he said.
The site was being cleared for the construction of 250 homes.
The ESB said the second loss of live was a devastating blow for the company and the colleagues of the victims.
ESB chairman Tadhg O’Donoghue and chief executive Padraig McManus, expressed their sympathy to Mr Healy’s family, friends and colleagues.
Mr Healy, of Tieraclea, Tarbert, joined ESB as an apprentice in 1971.
Last Friday, a colleague Patrick McCrohan, died in Cork University Hospital from injuries sustained in the switch gear room accident which is being investigated by the HSA.
