Abstract
Panelized wall systems are now extensively utilized in residential construction, which is recognized as a high-risk industry. A considerable number of construction injuries are reported every year. According to Occupational Safety & Health Administration (2005), 38,000 construction injuries occur each year. Safety on construction sites may not have the highest priority, as emphases of the construction industry are more on speed, efficiency, and economy. Furthermore, panelized wall systems have not been investigated in terms of hazard analysis. The primary purpose of the study was to identify the hazards related to panelized wall systems and to provide recommendations to improve the construction work environment. A critical incident technique was used to identify hazards through video-based observation, and the identified hazards were classified into five categories with twelve subcategories. Recommendations were provided for the hazards in each category. Based on the outcomes of the critical incident technique, risks associated with panelized wall systems were assessed using the MIL-STD-882B Risk Assessment Matrix.
