AMITE — After three days of a mandatory one-mile evacuation zone following an explosion at a facility in Roseland, Tangipahoa Parish officials said Monday that now only the roads and area closest to the incident site are under an evacuation order. 

La. 10 from U.S. 51 to East Russell Town Road, U.S. 51 from La. 1048 to North Street and La. 1048 from U.S. 51 to Mt. Gillion Church Road are still closed. 

"The public is urged to continue exercising caution in the area due to the ongoing presence of first responders and cleanup crews," officials said. 

Smitty's Supply caught fire and exploded Friday afternoon, blanketing Roseland in ash and setting oil on fire throughout the weekend. Firefighters are still on the scene working the still-burning explosion, but 90% of the fire has been contained.

Many of the residents evacuated to Amite and took up refuge in the Amite Community Center, which is now acting as an emergency shelter. According to officials, 42 people are staying there.

"To experience police officers going from door to door, knocking, saying you have to leave, you have to leave, like right now. People walking out, leaving medications, clothes, and personal items," one of the evacuees said. "I was so nervous. I didn't know what to do or which way to go."

Environmental Protection Agency officials have taken the lead in determining the cause of the fire as oil begins to fill the nearby Tangipahoa River.

State agencies and local businesses are helping both the workers and the residents displaced by the explosion. Click here to learn more.
