In this article, 46 chemical plants were investigated and assessed by Safety Department of Shanghai Institute of Technology in China. The safety management and technology ability and level were evaluated by the method of Safety Checklist Analysis (SCA) under the perspective of Safety Specialty Engineer. The risk levels of the overall of 46 plants were got. The SCA assessment presents the visible and invisible risks of the plants quantitatively and plainly. The results show that a majority of the plants have not fully implemented either on the good safety management or the reliable safety practice technology. The level of the overall risk indicate that about 35% of the plants reach the level of A (Scores 90), and others both lower than A, even 2 plants in the level of E, with total disregard for their health, safety, and well-being. Otherwise, 23 items were surveyed and judged one by one in safety assessment by SCA, and put forward suggestions for rectify and reform, which helps the plants recognize the reality of the situation and make better in the future.
