US Air Force 51st Fighter Wing Clarifies Non‑Hazardous Substance

Following the reported leak, the US Air Force's 51st Fighter Wing at Osan Air Base issued a statement confirming that the material found in a munitions container was not white phosphorus. Laboratory analysis detected no trace of the toxic agent, and officials described the observed degradation as a harmless surface corrosion caused by prolonged environmental exposure. The wing stressed that no long‑term health or ecological risks were present. Communication with Pyeongtaek officials finally succeeded at 5:51 p.m., shortly before the city withdrew its evacuation alert. The military continues to cooperate with local authorities to refine incident reporting procedures.
