    The objective of this work was to evaluate the impact of Virtual Environments (VEs) on safety analysis and participatory ergonomics.
    The developed method Safety Analysis with Virtual Environments (SAVE) is based on Participatory Ergonomics (PE), Task Analysis (TA), Work Safety Analysis (WSA), the standard EN 1050, and three‐dimensional (3‐D) functional modeling of the objects being analyzed.
    The materials of this work comprised machinery systems of six plants in a steel factory, which were implementing ongoing modernization projects. The results indicate that the SAVE method was applicable for safety analysis in the machinery layout design phase.
    According to the results, 58% of all identified hazards in a steel factory could be identified with VEs.
    A common understanding of designs, possibilities of evaluating and developing the system by the workers, and of providing training for operators and maintenance persons were the major contribution when using VEs in a safety analysis and applying a participative ergonomics approach
