Louisiana — A massive explosion at a lubricant and chemical plant has forced the evacuation of hundreds of residents within a 1-mile radius, authorities confirmed Saturday.

The blast triggered a large fire that continues to burn as emergency crews work to contain the scene. ABC News reported that, despite the scale of the explosion, no injuries have been confirmed. The cause of the incident remains under investigation.

Officials ordered the evacuation of nearby homes and businesses, including an elementary school, as a precaution against potential toxic exposure. A major highway was also shut down, disrupting travel across the region.

Witnesses described a thunderous boom followed by towering flames and thick smoke visible for miles. Local authorities have urged residents to avoid the area until the fire is under control.

Hazmat teams are on-site to monitor air quality and ensure public safety. State officials said updates will be provided as the investigation progresses.

The explosion has reignited concerns about industrial safety in Louisiana, a state known for its concentration of refineries and chemical plants.
