Scenario definition
Document node, process unit, equipment, deviation, hazard, consequence, risk category, severity, and prepared-by context.
account_tree LOPA software
Make layer of protection analysis traceable from scenario to action.
SafeTrakX helps process safety teams run LOPA studies with structured scenario definition, initiating event analysis, conditional modifiers, IPL validation, mitigated frequency calculations, and linked corrective actions.
Why LOPA teams need structure
LOPA is only useful when assumptions and protection layers are visible.
Spreadsheets can calculate numbers, but they rarely preserve the engineering context. SafeTrakX keeps the study narrative, calculations, IPL validation, and follow-up actions in one governed record.
Risk calculation
Capture initiating event frequency, conditional modifiers, IPL PFD/RRF values, target frequency, mitigated frequency, and risk ratio.
IPL validation
Track whether each IPL meets independence, specificity, dependability, and auditability criteria before it is counted in the calculation.
Study flow
Move through the LOPA method without losing decisions.
SafeTrakX mirrors the working sequence safety specialists expect while making the record easier to review later.
- Define the node and scenario.
Capture the process unit, subsystem, hazard or deviation, consequence, severity category, and risk tolerance basis. - Analyze the initiating event.
Record the initiating event description, cause category, base frequency, and frequency basis. - Apply conditional modifiers.
Document enabling conditions, ignition probability, occupancy factors, and supporting assumptions. - Validate IPLs and decide.
Evaluate independent protection layers, calculate mitigated frequency, compare to target, and create actions when gaps remain.

Connected process safety
LOPA should not live alone.
Use LOPA alongside HAZOP, Bow-Tie, What-If, MOC, PSSR, recommendations, and process safety documentation.
FAQ
LOPA software questions.
What is LOPA software?
LOPA software helps teams document and calculate layer of protection analysis, including scenarios, initiating events, modifiers, independent protection layers, mitigated frequency, and risk acceptability.
Can SafeTrakX track IPL criteria?
Yes. SafeTrakX tracks IPL criteria such as independence, specificity, dependability, and auditability so excluded layers are visible and explainable.
Is this connected to PSM?
Yes. LOPA is part of the broader SafeTrakX process safety management module alongside PHAs, MOC, PSSR, recommendations, and documentation.
Make LOPA reviews easier to defend.
SafeTrakX keeps the calculation, engineering assumptions, IPL decisions, and actions together in one auditable process safety record.
