Veteran council lifeguard Stuart Keay was patrolling Mermaid Beach when he was called to the aid of the concreter at the construction site of a house on exclusive Hedges Avenue.
"My friend who is a builder on the site ran down to me and said, 'come quick, one of the workers is dead from electrocution'," Mr Keay said.

"He was cyanosed, he was blue," Mr Keay said.
"The builders were working on him. He was on his back and they were doing heart massage and resuscitation.
"I told them to take his shirt up and I put the defib pads on."
Mr Keay and other workers stood clear as the machine shocked the man once.
"We started the heart massage again and we did that until the machine said 'stand clear, shock advised'," he said.
"We shocked him again and then continued resuscitation and heart massage. I could feel a pulse, but I waited to see what the machine said.
"It said, 'no shock advised'. I knew then that he had a strong pulse.
Immediately after the man spoke, Mr Keay returned to his watch post on the beach.
"It's just another day at work," he said.
