The purpose of this study was to conduct a study on the relationship between risk assessment signal and safety in small and medium-sized workplaces. While the Serious Accidents Punishment Act, which will be applied to places of business with five or more employees, will be effected in January 2024, the accident rate in small- and medium-sized businesses is still high. Promoting safety behaviors and preventing accidents in small- and medium-sized businesses require analyzing the role of risk assessment, an integral part of the self-regulatory safety and health management system.
 In this regard, this study is aimed at examining the relationship between risk assessment and safety performance in small- and medium-sized businesses. The subjects of this study were 211 employees, working at small- and medium-sized businesses that hired less than 300 workers. The collected data were analyzed using the IBM SPSS 29 program, through frequency analysis and independent samples t test. The results revealed significant differences in the domains of safety climate and compliance, accident rates, safety as a top priority, and the level of risk behavior management in small- and medium-sized businesses, based on whether risk assessment was conducted or not. The businesses that conducted risk assessment, demonstrated a higher level of safety performance than those that did not. These findings confirmed that risk assessment is an effective system to improve safety behaviors and prevent accidents at small- and medium-sized businesses. Further research should be conducted on the implementation of risk assessment in small- and medium-sized businesses and their resultant safety performance, to encourage more companies to adopt this practice. This will also facilitate risk assessment to develop into an effective measure for preventing industrial accidents and protecting the health and lives of workers.
