Hazard recognition and risk perception are two important factors that are a focus of most safety training programs. According to previous research, unrecognized hazards could lead to underestimation of risks, which ultimately could lead to injuries and fatalities. The primary objective of this research was to assess hazard recognition and safety risk perception skills in the electrician trade among electricians in unions. Another goal of this study was to find possible correlation between level of engagement in safety training and hazard recognition and risk perception skills. The research objectives were accomplished by gathering data from sixty-seven apprentices and journeymen across the United States. Each individual was asked to find identify hazards and to assess the risk associated with each hazard. both groups of apprentices and journeymen are similar to each other in terms of hazard recognition and both are significantly different than an expert group.The result also shows that apprentices perceive the risk not significantly different than the expert group. The result will help understand the impact of the level of engagement of safety training on hazard recognition and risk perception skills of their workers. The result could also help electrical unions identify performance gaps in their training and ultimately improve safety behaviors with union electricians.
