Today, China has witnessed a rapid development in the economy, which has seen an explosive growth of the chemical industry. In this context, the safety risk of greater hidden dangers ensues. This paper describes the definition and the classification of safety risks those chemical enterprises face now. There is a reasonable level-to-level management of the risk sources in the chemical enterprises, where the concept of appropriate risk capacity was also introduced. The dangerous substances are also accommodated to a controllable probability of risk occurrence by controlling the appropriate risk capacity of chemical enterprises. A diamond forewarning model for enterprises’ safety risk is thereby established. Not only that, the safety risk management case in a chemical enterprise is cited to prove how the model proposed here is feasible and will be available for risk management.
