The aim of this research is to detect work accidents that may arise as a result of house construction operations carried out by PT. XYZ, using the HAZOP approach. HAZOP is a hazard analysis technique used to ensure safety in new or modified systems by identifying potential hazards or operational problems. This involves assessing the level of hazard and the risks associated with that hazard using probability and consequence analysis. The findings are then categorized using a Risk Matrix. Based on research findings, six types of industrial accidents have high priority risks: material spills, falls from heights, scattered materials, being pierced by metal tips, falling from scaffolding, and dust inhalation.
