Abstract |
: |
Many occupational accidents occur due to various factors such as stress, fatigue, overwork and poor supervision when undertaking construction projects. One of the most significant achievements when undertaking a construction project is accomplishing the project without major accidents. This study aimed to investigate the effects of stress, fatigue and workload on construction workers’ safety performance results using a questionnaire that evaluates situational awareness, stress, fatigue, mental demand, and physical demand. The study addresses how each factor relates to the root causes of accidents. Investigating the factors associated with accidents helps identify and minimize the associated mistakes or causes, reduce accidents, and improve construction projects’ safety performance. Data were observed and collected from a large electrical company using a Situation Awareness Rating Technique (SART) survey of 136 participants of 18 contractors working on the construction of electrical substations in the western area of Saudi Arabia. The survey results showed that most accidents occurred at the worker level because of their lack of awareness and training. Additionally, the findings presented that stress, mental and physical workloads significantly influenced on awareness and training programs that carried out by electrical construction companies. It is apparent that situation awareness affects contractors’ safety performance, and awareness levels, correlate with the position, age and experience of workers. In addition, fatigue, mental workload and physical workload have a direct effect on situation awareness. Therefore, all of the mentioned factors affect safety performance. Implementing a safe working environment with a minimum number of accidents requires improving all job levels according to their weaknesses and activating the safety management system with periodic reviews. |
