Fire broke out at 10:50 pm at the site of a logistics company, operating since 2011 in the Tianjin port sector with a floor area covering 46,000 m². At the time of the accident, the company had been storing on-site several types of hazardous substances: calcium carbide, toluene diisocyanate, ammonium nitrates, potassium and sodium, as well as 700 tonnes of sodium cyanide.
