Hierarchy in Risk
A mixer nip remains reachable, but the team changes its matrix cell from red to yellow after sleeve training and calls the result 'ALARP.' An engineered enclosure is technically available and still within the project scope. As the CSP, decide whether the lower score is evidence of adequate treatment or only a prompt to examine the physical exposure pathway.
Updated . Independent CSP-11 practice. Not BCSP-endorsed. No pass guarantee.
Decision rule
Inside a risk decision, take the highest hierarchy row still open.
Same rule as Class 2, applied to residual risk treatment.
In 20 seconds
- Inside a risk decision, take the highest hierarchy row still open.
- Risk treatment uses the same hierarchy: eliminate, substitute, engineer, admin, PPE.
- Risk scores do not demonstrate that a feasible higher control was evaluated.
- Apply ALARP only in its appropriate jurisdiction and with evidence of reasonably practicable measures.
How to apply Hierarchy in Risk
THEORY: Risk treatment is not a separate pyramid. Elimination still beats PPE after a risk workshop. CALC: None. FIELD: Workshop picks respirators while a substitute is approved. Specify the substitute. ASSESS: ‘Risk accepted’ stamped on an open substitution is the trap.
Worked case
Wrong first move: Accept PPE as treatment. Correct move: Close the higher row or document why it is truly closed.
Why the rule holds
Related: 02, 39, 116.
Same rule, different setting
A risk ranking paints an open rotating coupling “yellow / ALARP” because gloves dropped the score. A sealed coupling is still in the charter. You are the CSP. The question is whether a color can outrank the hierarchy.
A risk ranking paints a leading-edge deck “yellow / ALARP” because harnesses dropped the score. A horizontal lifeline and deck infill are still in the charter. You are the CSP. The question is whether a color can outrank the hierarchy.
Picture / model
Use the hierarchy to change the hazard source or exposure pathway before relying on behavior-dependent controls, interpret matrix arithmetic only within its ordinal limits, verify the installed treatment, and keep financial risk transfer separate from physical hazard control.
Exam traps
Original SafePath contrasts for Hierarchy in Risk. These are study traps, not recalled BCSP items.
| Trap | Correct read |
|---|---|
| ALARP / yellow | A reasonably-practicable judgment under applicable jurisdiction, supported by control evidence |
| Risk score / RPN | Ranking aid — does not pick the row |
| Avoid (financial) | Stop the activity — overlaps elimination only if you actually stop |
| Reduce (financial) | Loss prevention/reduction — still implemented via hierarchy |
Field move
A feasible enclosure addresses contact at the source; a color change from PPE alone does not show that the hazard is controlled.
Scenarios
Scenario 1 · Fundamental · CSP-11 D3.02
A press risk matrix changes from red to yellow after cut-resistant sleeves are issued. A feasible fixed enclosure is still being designed. What is the best treatment decision?
Best action: Evaluate and install the enclosure, verify safe task access, and reassess residual risk; sleeves may cover remaining exposure.
Why: A feasible enclosure addresses contact at the source; a color change from PPE alone does not show that the hazard is controlled.
Scenario 2 · Applied Scenario · CSP-11 D3.02
An optional solvent-cleaning step can be removed without affecting product quality. A manager proposes keeping it and buying a larger policy. Which strategy affects the exposure?
Best action: Avoid the unnecessary step and verify the process still meets requirements.
Why: Stopping a nonessential hazardous task removes this exposure; the other options change who carries the financial loss or who performs it.
Scenario 3 · Applied Scenario · CSP-11 D3.02
A coating shop compares a feasible non-isocyanate system with improved respirator training for a current isocyanate process. Which decision should the review make first?
Best action: Evaluate the substitute's full hazard and process performance, then determine residual controls; a score does not settle the comparison.
Why: Substitution can remove the specific isocyanate hazard but must be validated for new hazards and operational fit.
If the stem says this
| Stem signal | Best direction |
|---|---|
| risk matrix rates PPE as acceptable while engineering is open | take engineering |
| ALARP is claimed without closing higher rows | reject — close higher rows first |
| only training is proposed for a machine hazard | guard/engineer first |
| two answers work | higher hierarchy / system / design |
| higher control was honestly infeasible | document closure and take best remaining |
Check before you leave
- ✓ Risk treatment uses the same hierarchy: eliminate, substitute, engineer, admin, PPE.
- ✓ Risk scores do not demonstrate that a feasible higher control was evaluated.
- ✓ Apply ALARP only in its appropriate jurisdiction and with evidence of reasonably practicable measures.
- ✓ Administrative controls support engineered controls — they do not replace them by default.
- ✓ Document feasibility and effectiveness before relying on lower-tier controls.
- ✓ Monitoring verifies the chosen control still works.
Blueprint mapping
Hierarchy in Risk is the SafePath study class for CSP-11 D3.02 inside CSP-11 Domain 3, Risk Management (15%). CSP-11 expects safety professionals to evaluate risk systematically, select mitigation strategies, understand financial risk treatment, and keep risk under active review.
SafePath uses the publicly posted CSP-11 outline as a study map. It does not reproduce official exam content, and it is not affiliated with or endorsed by BCSP or Pearson VUE.

Hierarchy in Risk study questions
- What decision does the Hierarchy in Risk class train?
- Inside a risk decision, take the highest hierarchy row still open. This is independent SafePath CSP practice for CSP-11 D3.02. It is not an official BCSP item and it is not a pass guarantee.
- What exam trap shows up in Hierarchy in Risk?
- A common miss treats this as sufficient: ALARP / yellow The stronger read is: A reasonably-practicable judgment under applicable jurisdiction, supported by control evidence
- How does Hierarchy in Risk map to the CSP-11 blueprint?
- SafePath maps this class to CSP-11 D3.02 in Domain 3, Risk Management (15% of the published blueprint). Use the public outline for study planning. SafePath is not affiliated with or endorsed by BCSP.
