A Powercor electrical maintenance crew has been recognised for saving the life of Mr Gunsan, 45, after he had a heart attack while driving in St Albans.

Paul Debruyn, Rob Deluise, Mahar Elbodon, Theo Petropoulos and contractor Brian Baptist rushed to Mr Gunsan's aid after his car veered across the road and hit a fence on July 1.

The men have been nominated by Ambulance Victoria for 'community hero awards' and were last week presented with commendations.

Praising the crew for their rapid response, Mr Gunsan had no doubt they had saved his life.

"If not for them I wouldn't be standing here today," he said.

"All I can say is how grateful I am for what they did."

The men made their worksite safe before rushing to Mr Gunsan's vehicle, where they found him slumped across the steering wheel, unconscious.

"We knocked on the window to see if he was OK. There was no response and the guy was going blue," Mr Elbodon said.

"The car doors were locked so we worked together to break into the car and get him out."

The crew pulled Mr Gunsan from his car with one man starting CPR while the others controlled the traffic until paramedics arrived.

Mr Gunsan was transported to hospital and has since made a full recovery.

"Luckily, we were there at the right time," Mr Debruyn said. "It happened in a quiet street in StAlbans and he might not have made it."

Paramedic Adrian Scrofani, who nominated the men for the awards, said that without their aid the outcome would have been very different. "The actions of these workers directly contributed to the successful resuscitation of this man."

Mr Debruyn said it was wonderful to be recognised by Ambulance Victoria, but he did not consider the group's actions particularly special. "All we really did is what you'd hope someone would do for you in the same situation."
