One person was killed and another was injured in a fire and explosion at a petroleum plant in the Chicago suburbs.

The Will County Sheriff’s Office said the incident occurred around 9:30 a.m. Tuesday morning at Seneca Petroleum in Lemont, a village about 28 miles southwest of downtown Chicago.

The sheriff’s office said fire and emergency crews arrived and had the fire under control around an hour later. One person was confirmed deceased at the scene.

The injured person was taken to Silver Cross Hospital in Joliet in unknown condition.

“Initial reports indicate that the explosion may be from an asphalt tank. Fire personnel do not believe that any type of hazmat situation has occurred and there is no danger to the public,” the sheriff’s office said in a news release.

Video footage of the scene shows scorch marks on multiple tanks, smoke rising and severely damaged railings and walkways.

Officials from both the U.S. Occupational Safety and Health Administration (OSHA) and ComEd, the local power utility, were also at the scene as of Tuesday afternoon. The explosion brought down some nearby power lines.

A nearby CITGO refinery was not affected by the incident.

Several roads around the plant were closed and were expected to remain closed for several more hours. Drivers were advised to avoid the area.

The incident came on the heels of two other deadly industrial explosions. In February, an explosion at an Ohio metal factory killed one worker and injured more than a dozen others. In April, one worker was killed and four others were injured in an explosion at a Nebraska ethanol plant that the state fire marshal’s office described as an accident.
