An investigation concluded in February 2016 that an overheated container of dry nitrocellulose stored at a container storage station in Tianjin's Binhai New Area triggered the initial explosion, igniting a chain reaction involving large quantities of hazardous chemicals, including approximately 800 tonnes of ammonium nitrate.
On 12 August 2015, a series of explosions struck the Port of Tianjin in northern China. The first two blasts occurred 33 seconds apart, with the second being far more powerful. Fires burned uncontrolled through the weekend, producing eight further explosions on 15 August, causing widespread destruction across the facility.
The disaster killed 173 people, including 104 firefighters, and injured 798 others. It prompted scrutiny of China's chemical storage regulations and safety enforcement, and the scale of destruction was compared internationally to the September 11 attacks. Authorities launched investigations leading to regulatory and accountability measures.
