Construction workers’ awareness of safety information depending on physical and mental load

Construction is one of the most dangerous occupations. The prominent reason for worker accidents unsafe behavior, particularly rooted in inability to recognize and appropriately respond risk factors. Previous studies have investigated perception comprehension construction hazards safety information laboratory settings. A relationship has been found between workload workers’ situation awareness (SA), a useful concept understanding comprehension. However, it necessary investigate actual environment increase real-world applicability research results. This experimental study analyzed SA relation physical mental workloads acquired while performing work at site. Perception (Level-1-SA) (Level-2-SA) were measured using Global Assessment Technique as subjects walked inside facility under performed inspection or works. Statistically significant differences safety-related information. It was also that load negatively affected SA. provided external validation previously effects on elements real sites. study’s findings can improve behaviors help suggest directions management guidelines.
