Risk assessments identified sources of potential hazards related to workstation
activities, then estimated the probability of occurrence and severity for each risk
identified. The product of these two factors determines the level of criticality of the
risk. This analysis determines the extent of risk control at each workstation. The most
critical risks are given priority in the identification of protection or prevention
measures. In order to clarify the results, various levels of criticality were determined.
Among the risks considered ‘acceptable’ (or ‘controlled’), we find two levels of
criticality classification: weak and insignificant. ‘Unacceptable’ (‘uncontrolled’) risks
are divided into three classes: moderate, substantial and intolerable.
