There’s a fire with explosions at a Sioux Falls business. 

Witnesses first reported the fire to KELOLAND News just after 5 p.m.  Video from the Billion Toyota Auto Dealership nearby shows large flames and heavy smoke at A-OX Welding Supply in Sioux Falls. 

Paramedics Plus tells KELOLAND’s Dan Santella no one was hurt in the fire.  The initial call was for multiple propane tank explosions at the business.  

As of 6:12 p.m., Sioux Falls authorities were closing roads in the area and evacuating people in a one-mile radius. The Red Cross has opened a comfort shelter at their 808 West Avenue North office for evacuated residents affected by the fire.

This is a developing story.  KELOLAND News has a crew on the scene; we’ll update this story with new details as those are confirmed.
