The technical specification for safe production of chlor-alkali enterprises in Shandong Province (for trial implementation) is currently in the stage of soliciting comments. This indicates that Shandong will strengthen the safety management of chlor-alkali enterprises by standardizing safety production techniques, improve the safety management level of enterprises, and ensure that hazardous chemicals such as liquid chlorine and caustic soda Production and storage security.
Shandong is a large chlor-alkali province with 42 chlor-alkali enterprises and an annual production capacity of 4 million tons, accounting for about one-third of the country's total. The main products of the chlor-alkali industry, such as liquid chlorine and caustic soda, are hazardous chemicals, and there are great risks in their production, storage and transportation. According to statistics, in the safety accidents caused by dangerous chemicals, chlorine accounted for 22% of all accidents caused by chlorine, and 66% of these accidents were caused by violations of company regulations and negligence. In order to strengthen safety management, Shandong has issued three hard rules for improving safety entry thresholds for construction projects, strict project safety approval and “three simultaneous†management, and strengthening the supervision and inspection of projects under construction and completed projects.
The chlor-alkali production safety specification to be issued this time in Shandong will be based on the surrounding environment of the site, the general layout of the plant site, the classification of the fire hazard of the building and the fire-resistance limit, the fire prevention distance between the plant and the warehouse, the safe evacuation of the factory buildings and warehouses, combustible and assisting gasses. Fireproof distance of storage tanks, fireproof spacing of production equipment, fireproof spacing of flammable liquid storage tanks, firefighting lanes, building structures, firefighting water supply and extinguishing facilities, heating ventilation and air conditioning, saltwater process, electrolysis process, rectification process, chlorine drying, The liquefaction and filling processes are subject to detailed safety regulations. In addition, the construction of lightning protection, pipeline layout, anti-static, site drainage, electrical work, hot work, equipment operations and high-level operations, lifting and lifting operations are also regulated from the production technology.
