This article investigates the understanding and manifestation of safety culture within the Swedish construction industry. Specifically, through 20 interviews with safety leaders, this study explores the connection between safety culture and structures and processes on construction worksites. The theoretical framework draws on different perspectives on organisational culture, in general, and safety culture, in particular. The results highlight the importance that is placed on management and leadership in developing safety culture, with leaders setting examples and being actively involved in safety practices. Safety regulations are seen as crucial tools for change, influencing safety culture significantly. The size of the company and characteristics of employees, including challenges posed by subcontractors and language barriers, also impact safety culture. Safety training is essential for directing behaviours towards a good safety culture, and housekeeping is identified as an indicator of safety culture. In the discussion, the matter of understanding safety culture in relation to specific structures and processes on construction worksites is analysed, problematised and connected to prevailing perspectives within safety culture research.
