4.2. Phase 2 – risk assessment
Once the results of the second step, i.e., the risks’ priority, are
obtained, it is possible to proceed to the third and fourth steps.
Here the model proposes the calculation of the frequency and consequence indexes, which are computed referring to Italian national
standard, UNI 7249:2007 (this standard is available also in English
as ‘‘Statistics on occupational injuries”). The equations used to calculate both of them are reported in (8) and (9).
