Abstract |
: |
Prophet Mosque expansion project in Al Madinah Al Munawwarah is one of the mega construction projects in Saudi Arabia. Understanding the factors affecting occupational safety and health of the workers in such a project could be helpful in improving the safety of the workers in the project itself and in similar construction projects. The objectives of this study were to study three important aspects that have impact on the safety performance of the project and to study the factors pertinent to these aspects. The three aspects were job content (or work conditions), safety culture and injury records. Two questionnaires, one for job content and the second for safety culture, were distributed among a sample of the project's workers and 162 responses were received. Analysis of the job content questionnaire revealed that job demand was high for the majority of the workers (average: 3.56 on a 5-point Likert scale). Furthermore, job control and social support were also high (averages are 3.64 and 3.73, respectively). However, job satisfaction was relatively low (average: 3.08), most probably due to high demands and job insecurity. On the other hand, the results of the safety culture questionnaire showed that average scores of safety culture dimensions were above average, being 3.91, 3.82, 3.77 and 3.67 for management commitment and supervision (MCS), safe working procedures and safety reporting (SPR), workers involvement and communication (WIC), and workers training and competence (WTC), respectively. This could be due to relatively higher safety standards followed in the project compared to other construction projects in Saudi Arabia. However, 25 out of 162 participants (15.4%) experienced at least one injury during their work in the project. The study presents detailed analysis of the relationships among some workers' characteristics (e.g., age, experience, occupation, education, work shift, working hours and nationality) in one side, and job content and safety culture in the other side. Analysis of the 1422 reported injuries revealed that the steel fixers and carpenters experienced two thirds and laborers experienced one fifth of the injuries. Also, most of the injuries targeted upper limbs followed by lower limbs. The most common injury causes (or accident types) were falling objects, struck by/against, slips/trips, hand tools and manual material handling in descending order. Furthermore, it was found that 48% of the injuries occurred within the time period 7:00 – 11:00 a.m., and about 81% occurred in summer and fall seasons (from June to December). Finally, there was significant association of job demand and management commitment and supervision with major injury occurrence. The study recommends that measures to decrease job demands among workers and improve their job and payment security. This is expected to improve job satisfaction and, accordingly, readiness to perceive safety aspects. Furthermore, enhancement of management commitment to occupational safety and health is expected to positively reflect on the safety culture among construction workers and, thus, on reducing the accident rate. |
