Quantitative Risk Assessment (QRA) is summarised in these steps:
- Hazard Identification (HAZID), to determine hazard and categorisation of MAH
- Release Frequency Analysis, to calculate the total release frequency for all release scenarios through part counts
- Consequence Modelling, to model the consequences (JF, FF, PF, EX)
- Event Tree Analysis, to determine the potential end event likelihood
- Risk Assessment, to estimate the fire impairment and personnel risk during the loss of containment
