At least one person was killed and another injured in an explosion and fire Tuesday at a petroleum plant in Lemont, Local News Channel 5 NBC reported.
The Will County Sheriff's office confirmed the fatality just after 11 a.m. at Seneca Petroleum, located in unincorporated Lemont. Lemont Fire Protection Chief Daniel Tasso said one other person suffered a minor injury in the explosion.
Multiple emergency crews responded to the scene around 9:30 a.m., and roads were closed in the area.
The sheriff's office said initial reports indicated an explosion occurred in an asphalt tank at the plant, but it is not believed there is "any type of hazmat situation" or danger to the public.
"OSHA has opened an investigation with a contractor on the site, M&J Industrial Services, where one of their employees was fatally injured and another was injured at a workplace incident at Seneca Petroleum Company in Lemont, IL," OSHA spokesperson Scott Allen said in a statement. "OSHA has also opened an investigation with Seneca Petroleum Company. No further information will be available until OSHA has completed their investigation, which by law, they have six months to complete."
