Tool Choice
A review team has one weekend and five familiar acronyms. They propose an FMEA to explain how several failures combine into one solvent-release top event, a JHA to evaluate deviations in a process unit that has not been built, an FTA to improve permit-form wording, and a bowtie that counts two safeguards sharing the same power supply as independent barriers. You are the CSP. Choose the analysis method by the decision question, not by the team’s favorite template.

Decision rule
Pick the risk tool that can still change the decision.
RPN, matrix, FTA, LOPA are not interchangeable.
In 20 seconds
- Pick the risk tool that can still change the decision.
- Tool choice: JHA vs PHA vs FTA vs FMEA vs checklist — match the question.
- FTA for how a top event occurs; FMEA for failure modes of components/steps.
- Do not run the fashionable tool after decisions are frozen with no change path.
How to apply Tool Choice
THEORY: Simple jobs: JHA. Combinations: FTA. Layers: LOPA. Ranking only: RPN. CALC: RPN=SxOxD if used. Do not mix tools in one number. FIELD: Complex SIS argument scored only as RPN 48. Use LOPA or FTA. ASSESS: One matrix for every problem is the trap.
Worked case
Wrong first move: Force RPN. Correct move: Match tool to the decision still open.

Same rule, different setting
A team has a weekend and five acronyms. They want an FMEA on a single rare well-control leak that can cascade, a JHA on a process unit that does not exist yet, and an FTA on how to fill a permit. You are the CSP on the pad. The question is which tool matches the question you are actually asking.

Picture / model
Select a hazard-analysis technique by what is being analyzed and what decision must be made. JHA/JSA follows a job sequence; a process PHA examines process hazards and deviations; FMEA moves from item or function failure modes to effects; FTA works backward from a defined undesired top event; and bowtie organizes threats, prevention barriers, a central event, consequences, and mitigation barriers. The method is only useful when scope, assumptions, dependencies, actions, and verification are explicit.
Exam traps
Original SafePath contrasts for Tool Choice. These are study traps, not recalled BCSP items.
| Trap | Correct read |
|---|---|
| JHA | This job’s steps — task-level, existing or imminent work |
| PHA (HAZOP / what-if) | This process/unit — design and deviations before/while it exists |
| FTA | One TOP event — combinations, AND/OR, cut sets |
| FMEA | Each item’s failure modes — local effects, RPN = S×O×D |
| Bowtie | One event, barriers left (prevent) and right (mitigate) |
Field move
Field decision: A fault-tree analysis with the fire as the top event and credible causal gates..
Scenarios
Scenario 1 · Fundamental · CSP-11 D2.06
An engineer asks which combinations of loss-of-containment, ignition and failed isolation can cause a defined tank-farm fire. Which analysis best represents the top event with AND/OR logic?
Best action: A fault-tree analysis with the fire as the top event and credible causal gates.
Why: Evaluate the best response. Pick the method that matches the question: combinations to a top event, deviations in a process, a task sequence, or a component failure mode. A score is not a safeguard. An engineer asks which combinations of loss-of-containment, ignition and failed isolation can cause…
Scenario 2 · Fundamental · CSP-11 D2.06
A new solvent process is still on P&IDs before equipment purchase. The team must review deviations, safeguards and consequences across process nodes. Which method fits?
Best action: A process hazard analysis using a suitable HAZOP or what-if/checklist approach while design can change.
Why: Evaluate the best response. Pick the method that matches the question: combinations to a top event, deviations in a process, a task sequence, or a component failure mode. A score is not a safeguard. A new solvent process is still on P&IDs before equipment purchase. The team must review deviations,…
Scenario 3 · Fundamental · CSP-11 D2.06
Tomorrow a crew changes a pump seal on an existing line. The question is the actual sequence of isolation, drain, opening and reinstatement. Which analysis is most directly useful?
Best action: A task-specific JHA with the crew, paired with the required energy-control procedure.
Why: Evaluate the best response. Pick the method that matches the question: combinations to a top event, deviations in a process, a task sequence, or a component failure mode. A score is not a safeguard. Tomorrow a crew changes a pump seal on an existing line. The question is the actual sequence of isol…

Check before you leave
- ✓ Tool choice: JHA vs PHA vs FTA vs FMEA vs checklist — match the question.
- ✓ FTA for how a top event occurs; FMEA for failure modes of components/steps.
- ✓ Do not run the fashionable tool after decisions are frozen with no change path.
- ✓ 5-why without evidence is not a tool win.
- ✓ Bowtie and LOPA appear as layer thinking — independence matters.
- ✓ Wrong tool is a named error code (TOOL).
