The research was carried out to statistically evaluate the relationship between the safety measures at the construction sites and the actual and perceived knowledge levels of the employees about these measures.
Face-to-face surveys were conducted with the workers. The survey included some perception-based questions about preventive measures at the construction site, as well as determining the level of awareness of employees on occupational health and safety (OHS) practices. The data were analyzed with descriptive statistical methods and bivariate correlation analysis.
The actual knowledge levels of workers on OHS measures in the workplace is significantly lower than their perceived knowledge levels. However, there is a positive, linear and strong relationship between the actual knowledge levels of the employees about some OHS rules applied in the workplace and the general level of knowledge they perceive about themselves. Some protective measures such as occupational safety expert, OHS board, employee representatives, training and information activities at construction sites positively affect the safety awareness of employees. However, low-frequency and documentation-intensive activities such as risk assessment, emergency activities and periodic controls have no or weak correlations.
Perception-based opinions of construction site workers on occupational safety issues are transformed into numerical data and analyzed with a quantitative method.
