MECHANIC FALLS — Authorities evacuated Elm Street Elementary School on Tuesday morning after a report of a propane leak, a fire official said.

The leak was reported by school personnel shortly after 8:30 a.m.

When firefighters arrived a short time later, school administrators were in the process of emptying the building of students, according to Deputy Fire Chief Jon Damon.

A section of Elm Street was closed to traffic during the evacuation for roughly half an hour, police said.

School maintenance staff located the leak and shut off a valve before firefighters arrived, Damon said.

The building was turned over to a contractor to repair the leak and students didn’t return to school Tuesday, Damon said.

School officials reported the leak was fixed before the end of the school day.

No injuries were reported.

“The Elm Street School staff did a great job of getting everybody evacuated before our arrival,” Damon said.

Fire departments from Oxford and Poland provided mutual aid.
