Emergency Response at Osan Air Base
Emergency services received a report regarding the release of a toxic substance at approximately 16:54 local time at Osan Air Base, also known as K-55, located in the Seotan-myeon area. Fire departments and police units were dispatched to the scene, deploying nine vehicles and 31 rescue workers to secure the area.
City Alert and Evacuation Order
The municipal authorities of Pyeongtaek issued an emergency alert to local residents, advising them to immediately move to a safe place and avoid contact with the substance. According to reports, no one was injured in the incident, and authorities lifted the evacuation order after about half an hour following decontamination efforts by South Korean fire services and the US military, as reported by the Yonhap news agency.
Investigation Into the Cause
Following the incident, police and military representatives announced that an investigation would be launched to determine the exact causes and circumstances of the event. In interviews with local media, police confirmed that the initial report originated from the US military, and chemicals most likely leaked from ammunition.
“Our emergency response personnel are currently addressing a limited-scope incident on the installation. The matter is being handled with the utmost care, as a priority, and without undue delay,” the base stated in a communication cited by Reuters.
Properties of White Phosphorus
White phosphorus is a substance used in ammunition and other military equipment. Upon contact with oxygen, it produces a dense white smoke, which is why it is also used to create smoke screens. The substance is highly reactive and can spontaneously ignite in air, while contact with it can cause severe burns, and inhaling large amounts of smoke can pose a fatal threat.
