Safety culture (SC) plays a key role in reducing and preventing occupational accidents and has become a subject of study and interest for several organisational sectors. Many conceptual models have been developed within the scope of SC to capture its most relevant dimensions; however, the need for improvement in these models has been identified. In light of this issue, this systematic review aims to provide contributions to the refinement of SC models. Starting from the model proposed by Fernandez-Muniz et al. (2007), an attempt was made to identify other relevant dimensions that should be considered to understand safety performance better. The review was based on the standard protocol built according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement and included 33 articles. The review identifies, in addition to the variables already covered in Fernandez-Muniz et al. (2007)' model, other significant variables at the individual (e.g., workers' attitudes), group (e.g., supervision) and organisational (e.g., work demands) levels that contribute to workers' safety performance.
