Wood pellet plant explodes

An explosion at Inferno Wood Pellets Co.'s plant in Rhode Island, US on 20 August was caused by dust.

The blast resulted in a four-alarm fire which saw crews from East Providence, Seekonk, Providence, Pawtucket, Warren and Barring respond.

The explosion occurred at around 2.35pm and proved difficult to extinguish due to the flammable material inside. Fire fighters were, at one point, ordered out of the factory when part of the building's roof collapsed.

One worker suffered first- and second-degree burns and was taken to Rhode Island Hospital.
