1. During a worksite risk review, a measurement departs from the recent trend. The
OHSE practitioner is reviewing the risk assessment before the next work phase
begins, and a customer, worker, patient, client, regulator, or manager may act on
the decision. The work concerns Hazard identification across physical, chemical,
biological, ergonomic and psychosocial exposures. What should the professional do
first? The current review includes 9 traceable entries linked to the risk assessment;
the newest entry is 6 minutes old, and the next decision point is in 25 minutes.
A. Rely on a verbal assurance from the team and close the risk assessment without recording how the
issue affecting Hazard identification across physical, chemical, biological, ergonomic and psychosocial
exposures was resolved. It would also ignore that the newest current evidence is 6 minutes old.
B. Observe the real task and worker needs, identify load, posture, repetition, duration, and environmental
factors, redesign the work where practicable, and verify residual risk after changes.
C. Continue with the original plan and add a generic note that Hazard identification across physical,
chemical, biological, ergonomic and psychosocial exposures was reviewed, without stating what was
checked. It would also ignore that the newest current evidence is 6 minutes old.
D. Use the result from a previous case as the main evidence for this risk assessment, even though a
measurement departs from the recent trend in a 9-entry review with 25 minutes to the next decision
point and newest evidence 6 minutes old. It would also ignore that the newest current evidence is 6
minutes old.
Correct Answer: Explanation: For Hazard identification across physical, chemical, biological,
B ergonomic and psychosocial exposures, the safest defensible response is to
resolve the material uncertainty using current evidence before approval. This
action preserves an auditable decision trail and reduces the risk of
musculoskeletal harm because a generic checklist replaced assessment of the
actual task.
2. At a permit-to-work briefing, the contractor finds that an earlier entry has no
supporting evidence while checking the exposure sample. Another team member
compares the observation with the decision criterion. For Risk estimation, control
selection and application of the hierarchy of controls, which evidence should carry
the greatest weight? The current review includes 2 traceable entries linked to the
exposure sample; the newest entry is 7 minutes old, and the next decision point is
in 45 minutes.
A. A verbal recollection from a previous permit-to-work briefing, offered during this 2-entry review, that is
not linked to the current exposure sample or the evidence for Risk estimation, control selection and
application of the hierarchy of controls.
B. A current task risk assessment linked to implemented controls, authorization, and effectiveness
checks.
C. A summary value copied from another case even though the next decision point is in 45 minutes,
without the source observations, criteria, or review history for this exposure sample.
D. A generic checklist marked complete after the fact, despite the newest current entry being 7 minutes
old, which does not show how the situation - where an earlier entry has no supporting evidence - was
resolved.
Correct Answer: Explanation: The strongest evidence is current, case-specific, and traceable to the
B actual work. For Risk estimation, control selection and application of the hierarchy
of controls, that evidence allows a qualified reviewer to understand what was
checked, against which criteria, and why the conclusion was reached.

3. A OHSE practitioner is preparing the permit for use after a contractor
coordination meeting. The record shows that the procedure in hand may not be the
current approved version. The decision involves Worker consultation,
competent-person duties and coordination of contractor activities. Which outcome
most clearly shows that control of the issue has failed? The current review includes
12 traceable entries linked to the permit; the newest entry is 8 minutes old, and the
next decision point is in 18 minutes.
A. For this 12-entry review, the permit is held while the OHSE practitioner obtains additional evidence
specific to Worker consultation, competent-person duties and coordination of contractor activities and
records the reason.
B. With 18 minutes to the next decision point, the issue is documented during the contractor coordination
meeting, responsibility is assigned, and the affected decision remains pending until the evidence is
adequate.
C. Misunderstanding or unmanaged risk caused by vague, one-way, or unsupported communication.
D. Because the newest entry is 8 minutes old, the team repeats the relevant verification for the permit
and updates the conclusion transparently when the new evidence supports a change.
Correct Answer: Explanation: This outcome represents the material harm or control failure that
C competent practice for Worker consultation, competent-person duties and
coordination of contractor activities is intended to prevent. The other choices
describe controlled responses rather than evidence of failure.
4. Following a pre-start safety review, a later reviewer asks how the contractor
handled a case where a correction was made without a documented reason. The
affected incident record relates to Exposure assessment, monitoring strategies and
interpretation against occupational limits. Which record would provide the best
audit evidence? The current review includes 5 traceable entries linked to the
incident record; the newest entry is 9 minutes old, and the next decision point is in
38 minutes.
A. A verbal recollection from a previous pre-start safety review, offered during this 5-entry review, that is
not linked to the current incident record or the evidence for Exposure assessment, monitoring
strategies and interpretation against occupational limits.
B. Representative exposure data linked to task, worker, duration, method, calibration, and the applicable
criterion.
C. A summary value copied from another case even though the next decision point is in 38 minutes,
without the source observations, criteria, or review history for this incident record.
D. A generic checklist marked complete after the fact, despite the newest current entry being 9 minutes
old, which does not show how the situation - where a correction was made without a documented
reason - was resolved.
Correct Answer: Explanation: An audit trail for Exposure assessment, monitoring strategies and
B interpretation against occupational limits must connect the actual condition,
applicable criteria, decision, responsible person, and any follow-up. The selected
evidence most directly provides that traceability.

5. While a OHSE practitioner is working through a hazard communication session,
the control measure cannot be finalized because repeat work differs materially from
the first result. The next decision is needed before communicating the conclusion
externally. What response best demonstrates professional judgment for Incident
notification, evidence preservation, investigation and root-cause analysis? The
current review includes 15 traceable entries linked to the control measure; the
newest entry is 10 minutes old, and the next decision point is in 58 minutes.
A. Repeat only the easiest check on the control measure and treat it as sufficient evidence for the whole
topic of Incident notification, evidence preservation, investigation and root-cause analysis. It would also
ignore that the newest current evidence is 10 minutes old.
B. Make the situation safe, preserve time-sensitive evidence, notify the required parties, and conduct a
structured investigation before closing corrective actions.
C. Approve the control measure because the hazard communication session is already behind schedule,
then review Incident notification, evidence preservation, investigation and root-cause analysis only if a
problem is reported. It would also ignore that the newest current evidence is 10 minutes old.
D. Delay documenting the discrepancy until after the hazard communication session, even though the
missing evidence could change the decision on Incident notification, evidence preservation,
investigation and root-cause analysis. It would also ignore that the newest current evidence is 10
minutes old.
Correct Answer: Explanation: Professional judgment is not a substitute for evidence. For Incident
B notification, evidence preservation, investigation and root-cause analysis, the
response should address the uncertainty, stay within authority, preserve the
record, and prevent losing evidence or allowing an uncontrolled hazard to
continue while the investigation is delayed.
6. A handover takes place after a worker consultation. The outgoing contractor
reports that two acceptable methods produce different outcomes, but the work
instruction still needs a decision on Safe systems of work, permits, isolation,
emergency arrangements and rescue planning. What information is most important
for the incoming reviewer to receive? The current review includes 8 traceable
entries linked to the work instruction; the newest entry is 11 minutes old, and the
next decision point is in 31 minutes.
A. Contemporaneous incident evidence showing conditions, actions, notifications, causes, and
corrective-action verification.
B. A verbal recollection from a previous worker consultation, offered during this 8-entry review, that is not
linked to the current work instruction or the evidence for Safe systems of work, permits, isolation,
emergency arrangements and rescue planning.
C. A summary value copied from another case even though the next decision point is in 31 minutes,
without the source observations, criteria, or review history for this work instruction.
D. A generic checklist marked complete after the fact, despite the newest current entry being 11 minutes
old, which does not show how the situation - where two acceptable methods produce different
outcomes - was resolved.
Correct Answer: Explanation: The incoming reviewer needs a record that is specific to the current
A case and can be independently checked. That is essential for continuity and a
defensible decision about Safe systems of work, permits, isolation, emergency
arrangements and rescue planning.
