**6. Conclusion**

This paper presents a graphical approach to explain the geographical distribution of the danger and target presence to show the results of scientific calculations, experts' opinions, and observations. Using geographical risk attributes instead of their simple values provides a spatial risk analysis approach to present the workplace's danger concentration points and neighborhoods. The model introduces a geometric definition for the probability and severity of the professional risk and material/immaterial barriers using the fuzzy space concept. This definition lets to separate the barriers' severity and probability effects and use the fuzzy set operations to determine the risk and barrier effects. It assigns a risk membership to each workplace location and aggregates all points to provide a total risk index. The model is appropriate for calculating the cumulative risk indexes for a group of targets and hazards.
