Nitrogen dioxide release caused by loading error
An explosion at the FrieslandCampina site in Borculo in July 2025 this year was reportedly caused by an error in the discharge of hydrochloric acid. The explosion released a mix of chlorine gas and nitrogen oxides. A truck driver reported to the wrong unloading point at the dairy company in Gelderland on 4th. Both the driver and a factory employee failed to properly check the cargo’s paperwork, resulting in the hydrochloric acid being unloaded into a nitric acid tank. Furthermore, an incorrect coupling was used during the unloading process, the company reported after its own investigation. An orange cloud containing chlorine gas and nitrogen dioxide was released and spread throughout the surrounding area. Around 21:00, the site was evacuated and the fire department was alerted. At 22:13, the tank exploded. The tank lid was later found in a meadow near the factory.
