In recent years, fire accidents have occurred frequently, and in 2019, especially accidents have occurred frequently, which has attracted the attention of relevant departments of government. One of the accidents was caused by a major fire caused by the short circuit of the circuit, and no high-temperature insulation protection was provided for the pipeline. The incident was as follows: a liquid ammonia explosion occurred in a steel mill in Jilin Province, and a major fire accident occurred in the main plant of a steel factory in Changchun City, Jilin Province. A total of 121 people were killed and 76 people were injured. The production equipment of the main plant and main plant of 17234 square meters was damaged, and the direct economic loss was 182 million yuan.
The direct cause of the fire: the main circuit of the company’s main plant, the west side of the women’s locker room and the adjacent electrical circuit of the second workshop’s power distribution room are short-circuited (whether or not the pipe protection is unknown) to ignite the surrounding combustibles. When the fire spreads to the ammonia equipment and the ammonia pipeline area, the high temperature generated by the combustion causes a physical explosion of the ammonia equipment and the ammonia pipeline, and a large amount of ammonia gas leaks and is involved in the combustion.
There were 395 people on the shop floor that day. The maximum possible amount of liquid ammonia leakage in an accident is estimated to be 15 tons.
