In accordance with the requirements of Document No. 116 issued by the State Administration for Work Safety regarding the strengthening of the management of safety instrumented systems in the chemical industry, all newly built chemical plants and hazardous chemicals storage facilities that fall under the category of “two key areas and one major hazard” must be equipped with safety instrumented systems that meet the specified standards. Before designing a safety instrumented system, it is necessary to clarify the process safety requirements, design objectives, and basis for such a system, which must be determined by the design institute. Risk identification must be carried out through process hazard analysis, safety instruments must be selected, and safety risks must be assessed in accordance with **laws, regulations, and standards.
