MURRYSVILLE (KDKA) — More than two dozen teachers and students were evacuated from Franklin Regional Middle School Wednesday because of a foul odor.

The odor was detected around 7 a.m. before most students arrived. In all, 24 teachers and two students were taken to Forbes Regional Hospital for respiratory evaluation.

The odor was caused by the battery from a floor scrubber, which overheated while charging.

Students were housed in the high school while the building was ventilated.

A “sniffing” of the building determined all was back to normal shortly before 11 a.m. Classes were allowed to resumed at the middle school.

The school district said no one suffered any serious injuries.
