Fire departments and police arrived at the scene, deploying nine vehicles and 31 rescue workers to secure the area following the toxic substance leak at the US base in South Korea.<\/p>\n<h4>Emergency Alert and Decontamination<\/h4>\n<p>The city of Pyeongtaek issued an emergency alert to nearby residents, recommending they immediately go to a safe place and avoid contact with the substance. According to the Yonhap news agency, no one was injured in the incident, and authorities lifted the evacuation order after about half an hour once South Korean fire services and US troops carried out decontamination procedures.<\/p>\n<h4>Investigation Into Ammunitions Leak<\/h4>\n<p>Following the incident, police and military representatives announced that an investigation would be launched to determine the exact causes and circumstances of the substance leak. Police informed local media reporters that the report originated from the US military, and the chemicals most likely leaked from ammunition.<\/p>\n<h4>Base Statement and White Phosphorus Properties<\/h4>\n<p>The base stated in a message quoted by Reuters that their emergency response services were currently managing a localized incident at the installation, handling the matter with the utmost care, priority, and without delay. White phosphorus is a substance used in ammunition and other military equipment; upon contact with oxygen, it produces a dense white smoke and is used to create smoke screens, being highly reactive and capable of spontaneous ignition in air while causing severe burns and lethal inhalation risks.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Emergency services responded to a toxic chemical leak at the US Osan Air Base in South Korea, prompting a temporary emergency alert, decontamination efforts, and an ongoing military and police investigation.
