Since there are many potential causes of failure, it would be nice to have a checklist to make the analysis organized and somewhat standard. As a guidance, a pretty good checklist is given by the Guide for Pressure-Relieving and Depressuring Systems, better known as API Recommended Practice 521 (API RP 521) table 1 in Section 3 (Table 13.1).
