ELPTank 80-8 circulation pump bearing failure -> mechanical seal failure -> butane-naphtha leak -> accumulated and ignited (burned 3 days)
Missing pump mechanical integrity program + no condition monitoring (vibration/LEL) + no remote emergency isolation valve
The recorded code ELP is an ISO 14224:2016 functional failure code (describes what the equipment failed to do). The damage mechanism (how it failed) is shown in the Mapping block above. The two are distinct dimensions in ISO 14224.
