Incident Description:
On December 8, 2022, the Des Moines Register reported an explosion and fire at an asphalt shingle recycling facility in Marengo, Iowa.
Firefighters tirelessly fought the flames until 4:30 a.m., when it was finally extinguished and the fire operation concluded, according to Marengo police chief Ben Gray.
Nine patients were treated at the University of Iowa Hospital, most with mild to moderate injuries. At least one person was reported to be in serious condition at the burn unit. Yahoo News played a 911 call made by one victim as they headed to the hospital.
The city of Marengo issued evacuation orders for homes east of Eastern Avenue, directing residents to head to Williamsburg, the neighboring town. The incident raised concerns about the safety and environmental impact of the plant’s operations, prompting further discussions between the Iowa Department of Natural Resources and company officials about the necessary permits and environmental regulations.
On January 15, 2023, the Gazette reported that the company had been sued by the Iowa Attorney General to try to force it to comply with an emergency order to clean up petroleum products and other toxic chemicals at the explosion site.
On June 13, 2023, KCCI reported that the company agreed to pay Iowa OSHA $95,000 as part of an informal settlement. On June 30, Powder & Bulk Solids reported that state investigators said the fire was accidental and started after flammable vapors ignited and exploded due to a mechanical failure.
