Abstract
Early signs of an organizational commitment to safety policies are manifested in the safety culture in that organization. Improving the safety culture of contractors can reduce occupational accidents in construction industry projects. Many scholars tend to research on this concept in order to achieve an approach to reducing occupational accidents. Numerous studies have attempted to identify the components affecting the safety culture using various methods and tools for measuring and assessing the safety culture; nevertheless, none of these studies measured the impact level of each of the evaluated factors on the safety culture. Hence, this study, assess the influence of each of these factors on the safe culture of contractors working in the construction industry. This study used a structural equation modeling approach to examine the safety culture assessment factors. Accordingly, ten factors affecting the safety culture were scrutinized to provide a conceptual model with ten predictable paths for evaluating the relationships between the variables. The data collected from thermal power plant construction projects were applied to test the hypothesized model experimentally using SEM-PLS method. According to the results of this study, it can be concluded that the factors of management commitment, appraisal of work hazards, supportive environment and communication among the factors influencing the safety culture of contractors in the studied projects had respectively the most impact on the safety culture of contractors operating in the thermal power industry, as well as the work pressure had the least impact on the safety culture..
Highlights
About one-third of the work-related deaths occur due to industrial accidents
CFA criteria are presented in Table 2, the results show that the CFA for all questions to assess the safety culture indexes is between 0.5 and 0.9, which is greater than 0.4, indicating that these criteria are suitable for measuring indexes
The supportive environment seems to have a relatively greater significance than the environmental supervision because a building worker affects constantly coworkers and is affected largely by the safe working environment. These findings indicate that the workers in safe working environments are more likely to have better working relationships with managers, supervisors and coworkers
Summary
About one-third of the work-related deaths occur due to industrial accidents The cost of these incidents is estimated at around 5,000,000 million dollars annually in the world due to the loss of human resources, materials, equipment and time [1]. The incident rates, which represent the number of injuries and illnesses in the construction industry, were significantly higher than the national average among all industries in most countries [5]. Accidents in this industry occur due to various causes that can generally be categorized as accidents from hazardous situations or physics and those caused by unsafe behaviors or actions [6].
