MORT / Barrier Analysis
A maintenance worker falls through a missing scaffold deck bay after handover. The report says “failed to tie off.” Which barriers were required, what evidence shows their condition, and how was the altered scaffold released for use?
Updated . Independent CSP-11 practice. Not BCSP-endorsed. No pass guarantee.
Decision rule
Advanced investigation follows energy and barriers, not a villain.
5-Why is a prompt. MORT/barrier maps the system.
In 20 seconds
- Advanced investigation follows energy and barriers, not a villain.
- MORT/barrier analysis maps controls that should have stopped the unwanted energy.
- Find missing, failed, or bypassed barriers — not only blame.
- Barriers include design, engineered, human, and supervisory layers.
How to apply MORT / Barrier Analysis
THEORY: Timeline, conditions, failed defenses, management system that allowed the gap. CALC: None. FIELD: Amputation with ‘inattention’ as root cause. Rebuild with the missing guard and why it stayed off. ASSESS: Stopping at the injured person is the trap.
Worked case
Wrong first move: Blame and close. Correct move: Map barriers and the decision that removed one.
Why the rule holds
Related: 20, 119.
Same rule, different setting
Process release investigation: list barriers (detection, isolation, shutdown, PPE) and find the broken AND in the control set.
Fall incident: guardrail missing, monitor absent, harness misused — barrier logic before blame.
Picture / model
Define harmful transfer → establish chronology → test barrier function and evidence → trace management causes → correct and verify.
Exam traps
Original SafePath contrasts for MORT / Barrier Analysis. These are study traps, not recalled BCSP items.
| Trap | Correct read |
|---|---|
| Investigation | Learn causes of an event |
| Audit | Sample conformity to standards |
| Root cause | System-level necessary cause |
| Contributing factor | Influenced but not alone sufficient |
| Barrier failed | Present but ineffective |
Field move
Field decision: Identify which barriers failed/missing/bypassed.
Scenarios
Scenario 1 · Applied Scenario · CSP-11 D2.04
You are the CSP reviewing a live decision at a semiconductor tool install. Operations proposes a convenience path. Once investigators establish the event sequence, what should they examine next to identify failed barriers?
Best action: Identify which barriers failed/missing/bypassed
Why: Evaluate the best response. After the sequence is known, ask which barrier failed and why the system allowed it. A caution to be careful does not restore the barrier. You are the CSP reviewing a live decision at a semiconductor tool install. Operations proposes a convenience path. Once investigator…
Scenario 2 · Applied Scenario · CSP-11 D2.04
You are the CSP reviewing a live decision at an offshore fabrication night shift. Operations proposes a convenience path. Which distinction between an incident investigation and a program audit is accurate?
Best action: Event learning vs conformity sampling
Why: Evaluate the best response. After the sequence is known, ask which barrier failed and why the system allowed it. A caution to be careful does not restore the barrier. You are the CSP reviewing a live decision at an offshore fabrication night shift. Operations proposes a convenience path. Which dist…
Scenario 3 · Applied Scenario · CSP-11 D2.04
Three independent barriers each P(fail)=0.1. Approx P(all fail) if independent AND?
Best action: 0.001
Why: Independence makes the joint failure probability the product 0.1³ = 0.001. Adding the three probabilities gives 0.3. One barrier is 0.1. Certainty would be 1.
If the stem says this
| Stem signal | Best direction |
|---|---|
| analysis stops at operator error | continue to missing barriers |
| barrier was bypassed routinely | fix the system that allowed bypass |
| only new procedure proposed while design barrier open | restore/add engineered barrier |
| two answers work | higher hierarchy / system / design |
| permanent fix delayed | install interim barrier |
Check before you leave
- ✓ MORT/barrier analysis maps controls that should have stopped the unwanted energy.
- ✓ Find missing, failed, or bypassed barriers — not only blame.
- ✓ Barriers include design, engineered, human, and supervisory layers.
- ✓ Recommendations restore or add hierarchy-smart barriers.
- ✓ Timeline plus barrier chart beats narrative-only reports.
- ✓ Independence of barriers matters.
Blueprint mapping
MORT / Barrier Analysis is the SafePath study class for CSP-11 D2.04 inside CSP-11 Domain 2, Program Management (25%). A high-weight management domain focused on measuring performance, investigating incidents, managing change, building systems, leading people, controlling records and resources, and interpreting data.
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.

MORT / Barrier Analysis study questions
- What decision does the MORT / Barrier Analysis class train?
- Advanced investigation follows energy and barriers, not a villain. This is independent SafePath CSP practice for CSP-11 D2.04. It is not an official BCSP item and it is not a pass guarantee.
- What exam trap shows up in MORT / Barrier Analysis?
- A common miss treats this as sufficient: Investigation The stronger read is: Learn causes of an event
- How does MORT / Barrier Analysis map to the CSP-11 blueprint?
- SafePath maps this class to CSP-11 D2.04 in Domain 2, Program Management (25% of the published blueprint). Use the public outline for study planning. SafePath is not affiliated with or endorsed by BCSP.
