Line rupture causes evacuation at plant

Tiffin firefighters responded to an air line rupture at American Fine Sinter, 957 Maule Road, early Sunday morning.

A Tiffin Fire Rescue Division spokesman said employees of the plant heard a hissing sound and evacuated the building, thinking it could have been nitrogen, hydrogen or natural gas.

Firefighters found an air line had ruptured on a piece of equipment and shut off the air line, he said.

No one was injured, the spokesman said.
