Firefighters have spent almost four hours fighting a blaze inside one of Victoria's largest power stations. Fire Rescue Victoria crews were called to the Yallourn Power Station, in the Latrobe Valley, just before midday after a Triple-Zero caller reported burning embers in a coal bunker from a lightning strike. Firefighters arrived to find the fire about 40 metres by 20 metres high. About 40 firefighters remain at the scene as they try to control the blaze. Peter Marshall, from the United Firefighters Union, said he was unsure how firefighters would control the fire. "What we have here is a critical crisis in the fire service, where firefighters' morale is so depleted, because the government have deserted them", he told Jacqui Felgate.
