内蒙古包钢板材厂1号球罐于2026年1月18日发生重大容器爆炸事故[1]。这起事故造成10人死亡、84人受伤，直接经济损失达6723万元[1]。
内蒙古应急管理厅公布的调查报告认定，该事故系重大生产安全责任事故[1]。调查显示，1号球罐长期受介质腐蚀、应力与交变载荷耦合作用，内壁发生了"碱应力腐蚀开裂+腐蚀疲劳"复合损伤，但相关单位未采取有效处置措施，最终引发爆炸[1]。
事故发生后投入了1300余人和70余辆应急救护车辆进行救援[1]。追责问责方面，内蒙古应急管理厅对62人追责问责[1]，其中7名涉嫌犯罪人员已被逮捕[1]，6人被建议移送司法机关[1]。
A major container explosion at Baosteel Sheet Plant in Inner Mongolia on January 18, 2026, claimed 10 lives and injured 84 people, resulting in direct economic losses of 67.23 million yuan.[1] The Inner Mongolia Emergency Management Department released its investigation report, determining the incident to be a major production safety responsibility accident and holding 62 individuals accountable.[1]
The investigation identified that Tank No. 1, a spherical storage vessel, experienced long-term corrosion and stress from the chemical medium it contained, leading to internal wall cracking.[1] The failure to implement effective remedial measures ultimately triggered the explosion, which resulted from a combination of stress corrosion cracking and corrosion fatigue damage.[1] The rescue operation mobilized more than 1,300 personnel and over 70 emergency medical vehicles.[1]
Among those held accountable, seven individuals suspected of criminal conduct have been arrested, and six others have been recommended for referral to judicial authorities.[1]
