Update (9:45 a.m.): The Franklin Fire Department announced that the cause of Tuesday morning's explosion on the Poplar Grove Middle School campus was caused by a leaking propane tank which was ignited by a space heater inside of a shipping container that was used as a workspace by construction crews.
FFD was dispatched to the scene at approximately 7:14 a.m. and school was scheduled to begin at 7:30 a.m.
“We’re very fortunate that nobody was injured, because numerous students, parents, school buses, and staff were in the area at the time of the explosion,” Franklin Fire Marshal Andy King said in a news release.
FFD reported that the propane gas had likely been leaking inside of the container all night when it exploded and was heard by residents throughout the surrounding area.
“He was lucky because he was very close to the blast," King said of the worker who started up the electric space heater.
According to FFD Public Information Officer Jamie Melton, the explosion has been ruled accidental.
