,5. A practitioner is while preparing for an audit or independent review and must make a decision about Worker consultation,
competent-person duties and coordination of contractor activities. What is the most defensible action? Consider the
decision while maintaining traceable evidence.
A. Replace a component or revise the design immediately before verifying the actual cause
B. Rely on personal preference when the controlled requirement is available
C. Accept a verbal assurance in place of objective evidence
D. Stop work when a critical control is absent or ineffective and correct or escalate the condition before continuing
Correct Answer: D
Explanation: For Worker consultation, competent-person duties and coordination of contractor activities, stopping unsafe work is appropriate when required
controls do not adequately manage the hazard. This is consistent with controlled utility safety and operations and the competency scope of this exam.
6. Which documentation is most useful when demonstrating proper control of Exposure assessment, monitoring strategies
and interpretation against occupational limits before authorizing the next dependent activity? Consider the decision with
current conditions documented.
A. Investigate likely causes systematically, changing one relevant variable at a time and retaining baseline evidence
B. Ignore the inconsistent data point solely because most other readings appear normal
C. Skip the prerequisite check because the schedule is more important than the documented sequence
D. Make several changes at the same time so the problem is more likely to disappear quickly
Correct Answer: A
Explanation: For Exposure assessment, monitoring strategies and interpretation against occupational limits, controlled troubleshooting separates cause from
coincidence and protects useful diagnostic evidence. This is consistent with controlled utility safety and operations and the competency scope of this exam.
7. A result associated with Incident notification, evidence preservation, investigation and root-cause analysis does not agree
with the expected condition during a field inspection. Which action is best? Consider the decision while maintaining
traceable evidence.
A. Make several changes at the same time so the problem is more likely to disappear quickly
B. Bypass a protective control temporarily without formal authorization
C. Proceed because the same task has been completed successfully on previous jobs
D. Verify isolation, grounding, clearance or protective measures using the procedure applicable to the specific utility hazard
Correct Answer: D
Explanation: For Incident notification, evidence preservation, investigation and root-cause analysis, high-consequence utility hazards require positive
verification of the protective state. This is consistent with controlled utility safety and operations and the competency scope of this exam.
8. Which sequence is most appropriate when a discrepancy involving Safe systems of work, permits, isolation, emergency
arrangements and rescue planning is found during troubleshooting? Consider the decision with current conditions
documented.
A. Continue normal operation until the next scheduled inspection even though the discrepancy is unresolved
B. Use a previous project record as evidence for the current condition without confirming equivalence
C. Use the approved procedure and governing requirements rather than relying on memory alone
D. Ignore the inconsistent data point solely because most other readings appear normal
Correct Answer: C
Explanation: For Safe systems of work, permits, isolation, emergency arrangements and rescue planning, approved instructions define the controlled method
and help prevent unauthorized or outdated practices. This is consistent with controlled utility safety and operations and the competency scope of this exam.

B. Skip the prerequisite check because the schedule is more important than the documented sequence
C. Make several changes at the same time so the problem is more likely to disappear quickly
D. Investigate likely causes systematically, changing one relevant variable at a time and retaining baseline evidence
Correct Answer: D
Explanation: For Legal duties, due diligence, records and enforcement consequences, controlled troubleshooting separates cause from coincidence and
protects useful diagnostic evidence. This is consistent with controlled utility safety and operations and the competency scope of this exam.
10. Which factor should be resolved before the practitioner relies on a result concerning Training-needs analysis,
competence verification and safety communication during final acceptance verification? Consider the decision with current
conditions documented.
A. Confirm calibration or functional checks and the suitability of the instrument range before accepting the reading
B. Make several changes at the same time so the problem is more likely to disappear quickly
C. Bypass a protective control temporarily without formal authorization
