Abstract: Anode production lines are mostly used in the electroplating industry, which are often in a high-temperature acid and alkaline environment. With high electricity consumption in the production process, interlocking and complex pipelines of production processes and environmental protection equipment, the flame spreads fast after a fire. In the investigation of this anode production line fire, there are some doubts and coincidences before and after the fire, leading to some extent interfered with the investigation ideas. Investigators explored the mechanism of the fire through scene cleanup, physical evidence identification, X-ray analysis, residue composition analysis, simulation experiments and other means to form a complete set of evidence chain. At last, we finally characterized the fire and accurately identified the cause of the fire, while proposing fire prevention measures and safety management countermeasures for the anode production line.
