      Background and aims

    The HCS standard includes listing of chemicals, labeling of chemical containers, preparation of material safety data sheets, writing plan and employee training programs. The aim of this study was to determine the influence of implemented program to enhance the knowledge and safety performance level of employees.

      Methods

      The knowledge level and unsafe act ratio were measured using both questionnaire and behavior checklist (with safety sampling method) before and after enforcing this interface.

      Results

    In this study, the mean and standard deviation of the knowledge level of employees related to chemical safety before enforcing the interface was 46% and 14%. However, after enforcing the interface, mean and standard deviation was 88% and 12%. The paired-t-test result in this parameter was significant (p-value <0.0001). The mean and standard deviation of knowledge level of employees related to warning labels before to enforcing the interface was 29% and 22%. After enforcing the interface, mean and standard deviation was 80% and 16%. The paired-t-test result in this parameter was significant (p-value <0.0001). The mean and standard deviation of the knowledge level of employees related to hazard communication methods before enforcing the interface was 25% and 11%. After enforcing the interface, mean and standard deviation was 79% and 16%. The paired-t-test result in this parameter was significant (p-value <0.001).

      Conclusion

    The obtained result revealed that enhancement of the knowledge related to chemical safety, hazard communication methods and warning labels was significant. Statistical paired-t-test and control chart methods was used to comparison between unsafe act ratio before and after enforcing the interface. The mean and standard deviation of unsafe act ratio before implementation of HCS program was 23.6% and 5.49%. However, mean and standard deviation of unsafe act ratio after implementation of HCS program was 18.1% and 6.18%. Therefore, after implementation of HCS program unsafe act ratio decreased (5.45%) significantly (p-value <0.0001). This result implies that chemical safety performance of employees was increased.
