UNION MILLS (AP) — Thick black smoke billowed from a LaPorte County grain elevator after a fire broke out where crews were working the day after a deadly explosion.

The fire Tuesday was at the top of the grain bins of the Union Mills Co-op but didn’t spread. No injuries were reported.

Facility owner Co-Alliance LLP says crews doing dismantling work likely exposing smoldering grain to the wind. Co-Alliance safety manager Shawn Lambert tells WSBT-TV the fire burned a rubber belt on a conveyor system.

LaPorte County sheriff’s Sgt. Brian Piergalski tells WNDU-TV that authorities evacuated some nearby homes because of explosion worries in the town of Union Mills about 30 miles southwest of South Bend.

Grain dust is the suspected cause of Monday’s blast that killed 67-year-old worker James Swank.
