China's relevant laws stipulate that large and medium-sized hazardous chemical production enterprises and residential buildings should maintain a safety red line of at least 1000 meters  However, with the rapid development of the city, many previously remote hazardous chemical production enterprises are gradually surrounded by residential areas  Once an accident occurs, it will cause immeasurable losses to the lives and property of the surrounding residents
In order to prevent the risks brought by hazardous chemical production enterprises to nearby residents, some experts suggest setting up a chemical park in the suburbs of the city to focus on the resettlement of hazardous chemical production enterprises originally scattered throughout the city, and strictly abide by the provisions of the 1000 meter safety red line
The newly-built chemical park has advanced equipment and strict management, and the early operation cost of settled enterprises will be greatly increased
