A SMALL guesthouse at a Yarwun property became a ticking time bomb that went off, when a slow-burning fire created a backdraft on Tuesday night.
Three fire crews were called to the fire about 9.45pm Tuesday, after neighbours heard an explosion.
Gladstone Fire Station officer Barry Maluga said the fire was well alight by the time fire crews arrived, but the guest house was unoccupied at the time. 'THE early indicators are that there has been a slow-burning fire in the structure over a period of a few days, resulting in a lack of oxygen, causing the windows to cave in and a sudden rush of oxygen which has caused a backdraft, resulting in an explosion and serious damage caused to the structure,' he said.
Mr Maluga said a fire investigator from Rockhampton and Gladstone scenes of crime police officers were called to inspect the burnt-out structure yesterday morning.
He said it was suspected the fire began when an electrical apparatus overheated, but investigations into the cause of the fire were continuing.
No one was injured during the incident, and the owners of the property were not present when the fire exploded.
