A large-scale industrial fire erupted in Richmond, Indiana, resulting in a massive cloud of black smoke covering the city. The fire broke out at a former factory site, which had been used for storing plastics and recycling materials. The cause of the blaze, which started in a tractor-trailer parked on the site, is unknown, but is being investigated by state and federal regulators who are assessing the environmental impact of the fire, including air quality. Richmond Mayor Dave Snow commented on the fire, stating that the site had been under a city order to clean up and remediate the site, as they knew the materials’ storage posed a fire hazard. The fire has been contained by three sides, according to the Richmond mayor, with no reports of injuries, but authorities urged people to evacuate within a half-mile radius of the site. People outside the radius who live downwind of the fire have been advised to keep windows closed and pets inside.
