A Toyota plant in Georgetown, KY was evacuated after an orange cloud of nitric acid gas was spotted around the plant. An investigation into the incident revealed a truck carrying liquid nitrous oxide hooked up to the wrong tank. The tank the truck hooked up to contained phosphorus. The chemicals mixing together caused the chemical reaction that was seen above the plant.
One person was transported to a local hospital with non-life threatening injuries. Nitric acid gas can cause breathing issues and skin irritation.
Toyota brought in an environmental cleanup company later that day to decontaminate the area. The company said “Toyota teams and external agencies worked diligently to safely and efficiently return to normal operations the following morning.”
