This risk
classification enables better identification of priorities. Risk control indicators are
constructed by aggregating the set of risks analyzed. Each risk is analyzed, and the
frequency and severity estimated. The product of these factors enables a level of
criticality to be established. The analysis of various tasks enables dangerous
situations to which employees are exposed to be identified. These situations are
grouped into different hazard categories. Finally, protection and prevention measures
both implemented and planned are associated with a prevention measure.
