SPARKS from a grinder appear to have been the cause of a shed fire north-west of Hamilton on Tuesday afternoon that destroyed four cars and a boat that were housed inside it.

Fire crews were called to a property on Leura Lane at about 3.55pm and arrived on scene to find a four-bay shed about 20 x 10 metres fully engulfed by fire.

CFA District 5 commander, Andrew Emery, said it took some time to bring the fire under control, with crews working hard in a difficult situation to save the contents.

“It took five crews just over an hour to bring the fire under control,” he said.

“Firefighting was hampered by fuel loads.

“Two vehicles were able to be saved outside the shed, but unfortunately four others and the boat were destroyed.

“One male was taken to hospital with smoke inhalation by Ambulance Vic.”

Mr Emery said the fire appeared to have been a result of material igniting around a work area.

“The cause was deemed accidental, caused by sparks from the grinder,” he said.

“The damage bill is estimated to be about $500,000. I’m not sure of the make and model of the cars - some project cars, some vintage gear I believe.”

12 CFA units from Hamilton, Warrnambool, North Hamilton, Grange, Strathkellar, Tarrington and Bainbridge brigades attended; Victoria Police and paramedics were also on scene.

Breathing apparatus crews completed mopping up after the fire was out and the scene was declared safe by 6pm.

Mr Emery said it was a timely reminder of the “dangers of hot works” and urged the community to exercise extreme caution when grinding, welding, slashing or mowing on their property.

Ensure a fire-resistant shield or guard is in place to stop sparks or hot metal and leave 1.5 metres of space clear of flammable material - or wet it down sufficiently to prevent the spread of fire.

Locals are also reminded to keep informed through the VicEmergency app.
