The purpose of this study is to activate the “Safety & Health Manager Assignment System”―a system that small and medium-sized enterprise (SME) in manufacturing industry with 20-49 employees is required to have safety and health manager for workers’ safety and health―through a research on whether a medium is provided between safety consciousness and safety behavior.
 The research was conducted to have suggestions for improving safety consciousness and safety behavior of workers in SMEs by promoting awareness and acknowledging importance on the safety leadership, safety consciousness and safety behavior.

Among them, 334 questionnaires excluding insincere responses were empirically verified. Using SPSS 24.0, basic statistical analysis, validity and reliability verification, and correlation were conducted. The analysis results are as follows: First, the safety leadership of the safety and health manager had a positive (+) impact on the safety consciousness of workers. Second, the safety leadership of the safety and health manager had a positive (+) impact on the safety behavior of workers.
