Investigators are looking into what caused a fire to break out at an Austintown manufacturer.

This started out as just a fire alarm call before midnight Thursday.

Crews had to force their way inside a Precision Foam Fabrication in the 37-hundred block of Oakwood Avenue.

No one was inside but firefighters were met by a lot of smoke.

21 News spoke with a fire captain, who says the sprinklers were able to douse most of the flames...and no one was hurt.
