The Franklin Fire Department reported the explosion appears to have been caused by a leaking propane tank and space heater, according to Franklin Fire Marshal Andy King.
King said the container was being used to store construction tools and serve as a workspace for construction workers, according to a release. He said it appeared there was a propane leak in the container overnight, which filled it with flammable gas.
According to the Franklin Fire Department, when construction workers arrived at the site Tuesday morning, they started an electric space heater, which appeared to have ignited the gas, causing the substantial explosion.
The investigation is ongoing.
