A truck disintegrated when the 50 tonnes of ammonium nitrate fertilizer it was carrying exploded after a road accident.
Eight people were injured in the blast late Friday including four firemen, a policeman and two motorists who had stopped to help at the accident.
And two fire trucks were also extensively damaged.
There is a two kilometre exclusion zone around the blast site 30 kms from Charleville in Queensland’s south-west, the ABC reported.
The Queensland Fire and Rescue Service (QFRS) says all injuries were non-life threatening but two firemen were still in hospital.
