UPDATE: Elkhart fire officials continue to investigate cause of blaze at RV plant

It was a total loss, but no one was hurt in a massive blaze at an Elkhart RV plant late Tuesday afternoon.

Firefighters were called to the scene around 3:46 p.m., dispatch confirmed.

The fire was at Forest River Plant 59, located in the 400 block of County Road 15 in Elkhart. As of about 5:15 p.m., firefighters had mostly controlled the fire and were working to put out hot spots.

No one was hurt, but the employees who were left at the plant had a scary end to their day on Tuesday.

"There were five to six employees still on scene who reported no injuries," Elkhart Fire Department Chief Chad Carey said. "Everybody was out and they hear explosions, some popping-type explosions at the time when they called 911. They said they heard it toward the front of the building, and by the time our units were set up, the fire had spread throughout the entire structure."

A thick plume of black smoke was visible from at least 15 miles away.

On Wednesday, a crew remained at the scene throughout the day to ensure hot spots did not flare up and out of control.

Elkhart fire officials say it may be days or even up to two weeks before the cause of the fire can be determined.

NewsCenter 16 reached out to Forest River in hopes of learning how the fire has affected their production and employees, but they declined to comment at this time.
