the Identifying the Unsafe Behaviors among Construction Industry Workers and Determining the Effect of Kiken Yochi Training (KYT) Intervention on their reduction in Iran

Nowadays, occupational related diseases and accidents are considered one of the main causes for mortality worldwide. However, Kiken Yochi Training (KYT) is one of the interventions to reduce the incidence of unsafe behaviors at workplace, yet there are few evidence-based studies on its effectiveness. This study was aimed to identify the unsafe behaviors among workers in the construction industry in Iran and determine the influence of Kiken Yochi Training intervention on their reduction. In this study, the unsafe behaviors of workers in Atieh Sazan construction Company, Tehran, Iran, were investigated. For this purpose, 452 workers were randomly selected and 11733 observations regarding unsafe behaviors were reported. In the second phase, Kiken Yochi Training was applied over three months, then observations were recorded once again. Socio-demographic questionnaire and Tarrant’s checklist were used. 25.69% of the recorded behaviors in the first phase and 18.57% after the intervention, were unsafe. Unsafe use of equipment and inappropriate ergonomic status were among the most common risky behaviors. The average percentages of unsafe behaviors before and after the intervention were reduced by about 36%. Kiken Yochi Training was effective in diminishing the unsafe behaviors among workers. There was a significant relationship between the number of unsafe behaviors, age, experience, type of occupation, educational status, and having a previous accident (P value <0.01). In the present study, it was concluded that the occurrence of unsafe behaviors among construction industry workers could be reduced by promoting awareness and raising knowledge. Moreover, it was recommended to have continuous monitoring, training sessions based on behavioral safety principles establishment, a safety culture in addition to reliance on academic experiences development.
