Using Tables 5 and 6 to estimate severity and likelihood levels, the two concerns were analyzed. The risk assessment team reviewed available information and performed the risk analysis using the PHA format shown in Figure 8. In the current state, both the SO₂ and DMDC risks were estimated to have a risk level of 12, an unacceptable risk level to the organization. Both risks were estimated to have a severity level estimated at 4 or “catastrophic” and a likelihood level of 3 or “very likely.” The PHA risk assessment tool provides a comparison of the risk levels before and after recommended risk treatment measures are implemented.
