Influence of Safety Leadership Styles on Safety Behaviour: The Mediating Role of Safety Climate, Knowledge, and Motivation in Indonesia's Oil and Gas Construction Project

Workplace injuries in the mining, oil, gas, and construction sectors in developing countries continue to increase. These work accidents occur because worker safety behaviors are low. Oil and gas construction projects in Indonesia are increasing because the capacity of oil and gas refineries is raised to meet the national demand for fuel oil. As such, occupational accidents at one of the construction projects in Indonesia have also increased. This study examines how worker safety behaviors are impacted by safety programs and transformational and transactional leadership styles. In addition, several mediation variables of the impact of leadership styles on safety behavior variables were also analyzed, including safety climate, knowledge, and motivation. The hypothesis was proposed using twenty-two direct and indirect tests with 675 workers as respondents. This study uses the structural equation modeling method for the tests. The results show that several hypothesis tests were accepted and there was positive relationship between variables, such as the relationship between safety climate and safety knowledge, as well as safety knowledge and safety behavior. These findings provide insight for HSE managers to provide examples of safety climate in the oil and gas construction projects.
