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 Risk estimation, control selection and application of
the hierarchy of controls. 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 Risk estimation, control selection and application of the hierarchy of controls was
resolved. It would also ignore that the newest current evidence is 6 minutes old.
B. Continue with the original plan and add a generic note that Risk estimation, control selection and
application of the hierarchy of controls was reviewed, without stating what was checked. It would also
ignore that the newest current evidence is 6 minutes old.
C. 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.
D. Verify the hazard and task conditions, select controls using the hierarchy of controls, confirm
authorization and emergency arrangements, and check effectiveness before work proceeds.
Correct Answer: Explanation: For Risk estimation, control selection and application of the hierarchy
D of controls, 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 starting work with controls that are
lower-order, unverified, or not matched to the actual hazard.
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 Worker consultation,
competent-person duties and coordination of contractor activities, 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 traceable record of consent or authority, information shared, recipient, purpose, referral details, and
follow-up responsibility.
B. 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 Worker consultation, competent-person
duties and coordination of contractor activities.
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
A actual work. For Worker consultation, competent-person duties and coordination
of contractor activities, 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 Exposure assessment, monitoring
strategies and interpretation against occupational limits. 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 Exposure assessment, monitoring strategies and interpretation against occupational limits
and records the reason.
B. Continued use of a degraded or drifting model without timely detection and response.
C. 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.
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
B competent practice for Exposure assessment, monitoring strategies and
interpretation against occupational limits 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 Incident notification, evidence preservation,
investigation and root-cause analysis. 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. Contemporaneous incident evidence showing conditions, actions, notifications, causes, and
corrective-action verification.
B. 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 Incident notification, evidence preservation,
investigation and root-cause analysis.
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 Incident notification, evidence preservation,
A investigation and root-cause analysis 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 Safe
systems of work, permits, isolation, emergency arrangements and rescue planning?
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. Verify the current permit or legal condition that applies to the activity, compare actual operation with
that requirement, record evidence, and notify or escalate deviations as required.
B. Repeat only the easiest check on the control measure and treat it as sufficient evidence for the whole
topic of Safe systems of work, permits, isolation, emergency arrangements and rescue planning. It
would also ignore that the newest current evidence is 10 minutes old.
C. Approve the control measure because the hazard communication session is already behind schedule,
then review Safe systems of work, permits, isolation, emergency arrangements and rescue planning
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 Safe systems of work, permits, isolation, emergency
arrangements and rescue planning. 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 Safe
A systems of work, permits, isolation, emergency arrangements and rescue
planning, the response should address the uncertainty, stay within authority,
preserve the record, and prevent a permit breach being continued or concealed
because the applicable condition was assumed rather than checked.
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 Legal duties, due diligence, records and
enforcement consequences. 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. 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 Legal duties, due diligence, records and
enforcement consequences.
B. 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.
C. 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.
D. Current, traceable evidence demonstrating Legal duties, due diligence, records and enforcement
consequences, linked to the applicable method, criteria, and decision record.
Correct Answer: Explanation: The incoming reviewer needs a record that is specific to the current
D case and can be independently checked. That is essential for continuity and a
defensible decision about Legal duties, due diligence, records and enforcement
consequences.
