What was the cause of the fire?

According to feedback from locals, the landlord called a welder to repair the elevator, but the welder's improper operation caused the fire. The factory that caught fire was a composite webbing factory near the Nishiban gas station. Thick smoke rose into the sky at the scene, and things fell from the factory building from time to time. According to nearby people, 4-5 people, including children, were still trapped in the burning factory. From the online video, everyone can clearly hear the heart-rending cry of the child.

At around 14:30 on August 8, a fire broke out in a 7-story factory building in Xiban Village, Chendai Town, Jinjiang, Quanzhou City, Fujian Province. , the fire was raging, and thick smoke poured out from the doors and windows. It is understood that there are many small factories related to shoe materials in this building. After the fire broke out, the fire department rushed into the rescue effort. Feedback from locals: Many private houses in Chendai are rented to others for use as factories, with no safety measures at all! This kind of factory really has poor awareness of prevention. Most of them are three-in-one. Although the government has been cracking down hard, there are always people who take risks! Jinjiang is known as the Shoe Capital and is one of the largest shoe industry information bases in the country. Although the fire broke out this time in a composite webbing factory, its neighbor was a small factory related to shoe materials. Once the fire spreads, the consequences will be disastrous. In Jinjiang, there are many small shoe factories that were converted from self-built houses, and their fire protection measures are almost zero. The shoe factory has many and complicated things, the assembly line has drying equipment, the weather is hot, some employees like to smoke, or the circuit may be aging or something. The hot weather in summer puts forward higher requirements for fire prevention. Especially jobs that require high-temperature work, such as electric welding. Relevant departments should strengthen supervision and take preventive measures in advance. Of course, the real convincing and credible cause of the fire still needs official investigation. From the exclamation of "It's on fire again" from a witness at the scene, we can conclude that there may have been a fire in Chendai Town recently.
