The specific reason for the sudden fire in the warehouse of a logistics company in Shijiazhuang, Hebei Province has not been found. It may be caused by someone throwing an unlit cigarette butt by mistake. On February 28th, 2020, a fire broke out in the warehouse of a logistics company at the intersection of Ping 'an North Street and Xiangyang Road. In the video, I saw that the logistics company was on fire, and the fire was very big. The scene was shocking, but fortunately there were no casualties. Because there are many cartons in logistics companies, if someone accidentally throws an unlit cigarette end, it is likely to cause a fire, and the consequences are very serious, because there are some combustibles in the warehouse of logistics companies. It is understood that the substances on fire at the scene are some cotton shoes, cotton and other items, as well as cartons filled with cotton shoes and cotton, which are very easy to cause fires and take a long time to put out. Moreover, the weather is dry in winter. Although the temperature is generally low, there are some cotton products in the logistics warehouse, and a little spark will easily cause a fire. At the scene of the fire, flames were soaring, black smoke covered the sky, and the fire was very strong. Residents living nearby immediately contacted firefighters after discovering it. Fortunately, the firemen arrived in time to put out the fire without causing too much material loss and casualties. In fact, no matter when, in winter or at other times, we should pay great attention to fire prevention. Especially when storing flammable materials in some warehouses, we must check all the hidden dangers that are easy to cause fires to avoid unnecessary material and personnel losses caused by fires. Especially in autumn and winter, the weather is generally dry and windy. A little carelessness may cause a fire under the action of the wind, causing irreparable losses. Life safety is no small matter, no matter when, we should put safety in the first place, investigate the hidden dangers that are easy to cause fires around us, and put an end to fires from the source.
