TAVARES, Fla. -

The state fire marshal has ruled the explosion at the Tavares Blue Rhino propane plant as accidental.

In the report released on Thursday, the state fire marshal closed the investigation into the fire that ignited at the plant on County Road 48 back in July.

Eight people were injured in the blast, including several who suffered critical burns. All have been released from the hospital.

It took months for the 53,000 propane tanks to be hauled away and for the facility to be reopened.

Tavares city officials estimate the explosions caused $3 million in damage.
