TAVARES, Fla. (AP) - Equipment malfunction and human error are among the possible causes of a series of explosions that spawned a 20-by-20 foot fireball at a central Florida propane plant and left eight injured.
Tavares Fire Chief Richard Keith identified the possible causes Tuesday, but said sabotage was not suspected.
The federal Occupational Safety and Health Administration launched an investigation into the Monday night incident at the Blue Rhino propane plant in a town northwest of Orlando, as did the Florida State Fire Marshal's office.
No one died, but eight workers were injured, four critically. Those injured include a worker who was hit by a car on a nearby road while fleeing the explosions.
