A plumber has been flown to the Alfred Hospital’s burns unit after an explosion at a Bonnie Doon service station this morning.

WorkSafe is investigating the incident.

WorkSafe understands the 33-year-old man was installing a deep fryer when gas was released and ignited. The source of ignition is not known.

It’s the second major gas explosion in several months and follows the death of a man at Waverly when a build up of gas in a van ignited in December. That incident is still under investigation.

WorkSafe’s General Manager of Operations, Lisa Sturzenegger, said more than 29,000 people suffered serious injuries at work in Victoria last year.

“While most are not as serious as this one appears to be, WorkSafe’s experience is that there is not much difference between the incident that kills and the one from which someone narrowly escapes injury.

“Inadequate supervision or training, complacency, a minor error, or being in the wrong place at the wrong time can have devastating consequences.

“All employers supervisors and workers need to re-focus their efforts on risk minimisation. We won’t stop all of these incidents and injuries, but a lot more can be done in every workplace to greatly reduce risks.”

Today’s explosion is the latest in a series of serious incidents this week.

A man died in Melbourne on Monday after falling three metres at a tile shop at Highett last Friday night.

Also on Monday a man, who was walking beside an excavator and helping to steady a seven metre long red-gum bridge beam was seriously hurt when part of a 1950s era railway bridge collapsed near Kerang.

At Warrnambool, a man received a knife wound while working at an abattoir. He was trimming a side of beef when the knife slipped and struck him on his upper chest and was treated at the Warrnambool Hospital.
