1Which standard fully superseded OHSAS 18001 as the international standard for Occupational Health and Safety Management Systems?
A.ISO 14001:2015
B.ISO 9001:2015
C.ISO 45001:2018
D.ISO 31000:2018
Explanation: ISO 45001:2018 fully replaced OHSAS 18001:2007 as the international OH&S management system standard, with the migration deadline expiring in 2021. ISO 14001 covers environmental management, ISO 9001 covers quality, and ISO 31000 covers risk management generally. ISO 45001 introduced the Annex SL high-level structure and stronger requirements on leadership and worker participation.
2What does the abbreviation OH&S MS stand for in ISO 45001:2018?
A.Office Health & Safety Methodology System
B.Occupational Health and Safety Management System
C.Operational Hazard & Safety Mitigation Strategy
D.Organisational Health & Safety Monitoring Standard
Explanation: OH&S MS stands for Occupational Health and Safety Management System — the framework an organisation uses to manage risks and opportunities related to worker health and safety. ISO 45001:2018 specifies requirements for such a system. Auditors must use the precise terminology of the standard when writing findings and reports.
3Which structure does ISO 45001:2018 share with ISO 9001:2015 and ISO 14001:2015 to facilitate integrated management systems?
A.Plan-Do-Check-Act only
B.Annex SL high-level structure
C.ISO 19011 audit framework
D.Annex A controls catalogue
Explanation: ISO 45001:2018 follows the Annex SL high-level structure (now Annex L of the ISO/IEC Directives) shared with ISO 9001:2015 and ISO 14001:2015. This common 10-clause structure with identical core text supports integrated management systems and combined audits. PDCA is a methodology embedded within the structure, while ISO 19011 governs auditing.
4Which document provides general guidelines for the implementation of an ISO 45001 OH&S management system?
A.ISO 19011
B.ISO 45002
C.ISO 31000
D.ISO 17021
Explanation: ISO 45002 provides general guidelines on the implementation of ISO 45001. ISO 19011 covers auditing of management systems, ISO 31000 covers risk management principles, and ISO 17021 covers requirements for bodies that certify management systems. Lead auditors should be aware that ISO 45002 is guidance, not certifiable.
5Which standard provides the auditing guidelines used by management system auditors, including ISO 45001 lead auditors?
A.ISO 17021-1
B.ISO 19011:2018
C.ISO 31000:2018
D.ISO 9000:2015
Explanation: ISO 19011:2018 provides guidelines for auditing management systems, including audit principles, programme management, and the conduct of audits. ISO 17021-1 specifies requirements for certification bodies (third-party auditors), ISO 31000 covers risk management, and ISO 9000 provides QMS vocabulary. ISO 19011 applies to first-, second-, and third-party audits.
6Which methodology is the underlying improvement cycle of an ISO 45001 OH&S management system?
A.DMAIC (Six Sigma)
B.Plan-Do-Check-Act (PDCA)
C.SWOT analysis
D.Kepner-Tregoe
Explanation: ISO 45001:2018 is built on the Plan-Do-Check-Act (PDCA) cycle. Plan corresponds to clauses 4-7 (context, leadership, planning, support), Do is operation (clause 8), Check is performance evaluation (clause 9), and Act is improvement (clause 10). DMAIC and SWOT are management techniques that may be used inside the OH&S MS but are not the underlying cycle.
7In ISO 45001:2018, the term 'worker' includes which of the following?
A.Only full-time employees of the organisation
B.Only employees and managers
C.Persons performing work or work-related activities under the control of the organisation, including contractors and temporary workers
D.Only the elected health and safety representative
Explanation: ISO 45001:2018 defines 'worker' broadly to include any person performing work or work-related activities under the control of the organisation, including managers, full-time and part-time employees, agency workers, contractors, and the self-employed. Auditors must verify that the OH&S MS scope and consultation processes cover all of these categories, not just direct employees.
8What is the difference between an 'incident' and an 'accident' in ISO 45001:2018 terminology?
A.They are exactly the same
B.An incident is any occurrence arising from work that could or did result in injury or ill health; an accident is the colloquial term
C.An accident is more severe than an incident by definition
D.An incident only includes near misses, never injuries
Explanation: ISO 45001:2018 uses 'incident' as the umbrella term for any occurrence arising from or in the course of work that could result in (near miss) or did result in (accident) injury and ill health. The standard intentionally avoids 'accident' to discourage the implication of randomness. Auditors should align findings with the standard's vocabulary.
9Which of the following is a distinctive feature added by ISO 45001:2018 compared with OHSAS 18001:2007?
A.A requirement to certify the system
B.Stronger requirements on top management leadership and worker consultation/participation
C.A requirement to publish all OH&S data
D.Removal of the hierarchy of controls
Explanation: ISO 45001:2018 strengthened requirements on top management leadership (clause 5.1) and consultation and participation of workers (clause 5.4) compared with OHSAS 18001. It also added explicit context-of-the-organisation analysis (clause 4.1) and risks and opportunities (clause 6.1). Certification is voluntary, public disclosure is not mandated, and the hierarchy of controls remains.
10What is meant by 'interested parties' in ISO 45001:2018?
A.Only the workers of the organisation
B.Only customers paying for products or services
C.Persons or organisations that can affect, be affected by, or perceive themselves as affected by an OH&S decision or activity
D.Only regulators with statutory authority
Explanation: Interested parties (clause 4.2) include any person or organisation that can affect, be affected by, or perceive itself to be affected by an OH&S decision or activity. Examples include workers and their representatives, suppliers, contractors, regulators, neighbouring communities, and clients. The OH&S MS must determine which interested parties and which of their needs are relevant.

ISO 45001 LA Study Tips from Top Performers

1Memorize the hierarchy of controls in order: elimination, substitution, engineering controls, administrative controls, PPE — clause 8.1.2 expects this exact order
2Map every requirement to the Annex SL high-level structure: clauses 4 (context), 5 (leadership), 6 (planning), 7 (support), 8 (operation), 9 (performance evaluation), 10 (improvement)
3Pay extra attention to clause 5.4 (worker consultation and participation) — it is a distinctive feature of ISO 45001 versus OHSAS 18001 and a common exam scenario
4Practice classifying findings: major NC = systemic failure or absence of a required process; minor NC = isolated lapse; observation = potential weakness; OFI = improvement suggestion not tied to a clause
5Use ISO 19011:2018 to recognise the audit programme vs audit plan, Stage 1 vs Stage 2 objectives, and what makes audit evidence sufficient and appropriate
6Use our AI tutor to draft non-conformity statements that cite the exact ISO 45001:2018 clause, the requirement, the evidence, and the impact

Frequently Asked Questions

What is the PECB ISO 45001 Lead Auditor exam?

PECB ISO 45001 Lead Auditor is a third-party certification exam that validates a professional's ability to audit Occupational Health and Safety Management Systems (OH&S MS) against ISO 45001:2018 using ISO 19011:2018 auditing guidelines. The exam is open-book, lasts 3 hours, and contains scenario-based and multiple-choice questions across seven competence domains. A score of 70% or higher is required to pass.

How hard is the ISO 45001 Lead Auditor exam?

The exam is considered advanced because it tests both deep knowledge of ISO 45001:2018 clauses 4-10 and the practical ability to apply ISO 19011 auditing principles to scenarios. Candidates need to recognise major versus minor non-conformities, draft findings against specific clause text, and reason about hazard identification and the hierarchy of controls. Most candidates spend 60-100 hours preparing across 6-10 weeks, often after attending a 5-day PECB training.

What jobs can I get with ISO 45001 Lead Auditor certification?

Typical roles include: ISO 45001 Lead Auditor with a certification body ($75-130K), OH&S Management System Auditor ($65-110K), HSE Manager / EHS Compliance Manager ($85-140K), Internal Audit Lead for industrial and construction companies ($70-120K), and Integrated Management System (IMS) Auditor combining ISO 9001/14001/45001. The credential is widely recognised by certification bodies, regulators, and multinational employers.

Is ISO 45001 Lead Auditor worth it in 2026?

Yes. ISO 45001:2018 fully replaced OHSAS 18001 in 2021 and adoption continues to accelerate, especially in construction, energy, manufacturing, and logistics. Lead Auditor is the credential most often required by certification bodies and large employers performing supplier and internal audits. Demand is reinforced by ESG reporting requirements, where worker safety performance is a measured pillar, and by integrated management systems combining ISO 9001, 14001, and 45001.

What is the difference between ISO 45001 Lead Auditor and Lead Implementer?

Lead Auditor is for professionals who plan, conduct, and report third-party or internal audits of an OH&S MS to verify conformity with ISO 45001:2018. Lead Implementer is for professionals who design, deploy, and operate the OH&S MS itself within an organisation. Both credentials cover the same standard but emphasise different competences: ISO 19011 auditing techniques for the auditor, and ISO 45002 implementation guidance for the implementer. Many senior HSE professionals hold both.
