STRATEGIES FOR CONSTRUCTION HAZARD RECOGNITION
Figure 1: The role of hazard recognition in injury prevention


Unfortunately, research has shown that many construction hazards are not recognized, valued, or adequately controlled prior to worker exposure. For example, Haslam et al. (2005) found that
42% of construction injuries occur due to workers lack of safety knowledge and hazard recognition skills. In another study, Carter and Smith (2006) evaluated typical activates in three construction projects and concluded that between 10 to 33.5% of construction hazards were not adequately recognized or assessed. More shockingly, Bahn’s (2012) recent study revealed that novice workers, on average, failed to identify 57% of hazards in work-representative

118 environments. When hazardous construction work situations are not appropriately identified, workers are unable to alter behavior in order to avoid hazard exposure. Although safety research has focused heavily on construction risk assessment and the selection of appropriate safety program elements, the fundamental prerequisite to improving safety – hazard recognition skill and knowledge – has not been given sufficient attention. Therefore, it is of utmost importance that effective and robust hazard recognition methods be developed that overcome the inherent limitations associated with current methods. The purpose of this study was to develop and experimentally field test a promising new strategy based on the underlying concepts of mnemonics, andragogy, and dynamic safety planning.
