Auditing Leadership Commitment Under Clause 5.1 of ISO 45001

Why Clause 5.1 Is One of the Most Important Clauses You Will Audit

Leadership commitment is the engine of any effective occupational health and safety management system. Without genuine commitment from top management, the rest of the system is just paperwork. ISO 45001 recognises this, which is why Clause 5.1 places significant obligations directly on top management rather than on the health and safety team alone.

When auditing leadership commitment under Clause 5.1 of ISO 45001, you are not checking whether the CEO signed the policy document. You are testing whether the people who run the organisation actually drive the OH&S management system, or whether they have simply delegated it away and forgotten about it. That distinction matters enormously, and it is what separates a meaningful audit from a box-ticking exercise.

This article walks you through what Clause 5.1 actually requires, what evidence to look for, how to structure your interviews with top management, and the most common gaps auditors find. Whether you are conducting an internal audit or preparing for a certification audit, these practical insights will help you audit leadership commitment with confidence.

What Clause 5.1 of ISO 45001 Actually Requires

Clause 5.1 of ISO 45001 sets out a list of specific actions and behaviours that top management must demonstrate. The clause is not vague. It is explicit, and that explicitness is useful for auditors because it gives you concrete criteria to audit against.

The key requirements include that top management must:

• Take overall accountability for the prevention of work-related injury and ill health
• Ensure the OH&S policy and objectives are established and are compatible with the strategic direction of the organisation
• Ensure integration of the OH&S management system requirements into the organisation's business processes
• Ensure the resources needed for the OH&S management system are available
• Communicate the importance of effective OH&S management and conforming to the system requirements
• Ensure the system achieves its intended outcomes
• Direct and support persons to contribute to the effectiveness of the system
• Ensure and promote continual improvement
• Support other relevant management roles to demonstrate their leadership in their areas of responsibility
• Develop, lead, and promote a culture in the organisation that supports the intended outcomes of the OH&S management system
• Protect workers from reprisals when reporting incidents, hazards, risks, and opportunities
• Ensure the organisation establishes and implements processes for worker consultation and participation
• Support the establishment and functioning of health and safety committees

That is a substantial list. Notice that several items go beyond process and documentation. Promoting a safety culture, protecting workers from reprisals, and directing people to contribute are behavioural requirements. They cannot be verified by reviewing a document. They require interview evidence, observation, and triangulation across multiple sources.

How to Approach the Audit of Clause 5.1

Start With a Document Review, But Do Not Stop There

Before your interviews, review what the organisation has documented. Look at the OH&S policy to confirm it has been signed by an appropriate member of top management. Check whether the policy is dated, whether it has been communicated to workers, and whether it reflects the organisation's current context.

Review the management review records. These records are one of the clearest indicators of whether top management is genuinely engaged with the OH&S management system. Ask yourself: are the review minutes substantive, or do they read like a rubber stamp? Are action items followed up? Are decisions made and resources committed?

Look at the OH&S objectives and check whether they have been set at relevant functions and levels. Then ask whether resources have been allocated to achieve them. A set of ambitious safety objectives with no budget attached tells you something important about the depth of leadership commitment.

Check whether there is evidence that OH&S requirements have been integrated into business processes. This might appear in project planning documents, procurement procedures, or operational planning records. Integration is one of the harder requirements to verify through documents alone, so use what you find here to build your interview questions.

Interview Top Management Directly

This is the part of the audit that many auditors find uncomfortable, particularly when auditing senior executives. The discomfort is understandable, but you need to push through it. Clause 5.1 places obligations directly on top management, which means top management must be interviewed.

If you are conducting an internal audit, you may be auditing your own managers. If you are a lead auditor conducting a certification audit, you may be sitting across from the CEO or Managing Director. Either way, your role is the same: gather objective evidence of whether the requirements are being met.

Useful interview questions for top management under Clause 5.1 include:

• How do you personally demonstrate your commitment to the OH&S management system?
• Can you describe a recent decision you made that was influenced by OH&S considerations?
• How do you ensure that safety is integrated into business planning and project delivery?
• What happens in this organisation when a worker reports a hazard or near miss?
• How do you support managers below you to fulfil their safety responsibilities?
• What resources have you committed to the OH&S system in the past twelve months?
• How do you know the OH&S management system is achieving its intended outcomes?

Listen carefully to the answers. A leader who is genuinely committed will answer these questions with specific examples. A leader who has delegated everything to the safety team will give vague, generalised responses and may struggle to recall specifics. That pattern of response is itself evidence.

For guidance on structuring your interview technique, the article on audit interviewing techniques every auditor should master covers open questioning, probing, and active listening in detail.

Observe Leadership Behaviour During the Audit

Observation is an underused audit technique when it comes to leadership. When you conduct a site walk, pay attention to how senior managers interact with workers. Do they stop and talk to people on the floor? Do they ask about hazards? Do workers seem comfortable raising issues with them?

If you observe a manager walk past an obvious hazard without acknowledging it, that is evidence. If workers tell you they would never raise a safety concern with their manager because nothing ever happens, that is evidence. If the safety committee minutes show the same unresolved issues appearing month after month with no management response, that is evidence.

Observation evidence needs to be recorded carefully and described factually. Do not write subjective commentary. Write what you saw or heard, when, and in what context.

Common Gaps Auditors Find Under Clause 5.1

Top Management Cannot Describe Their Own OH&S Responsibilities

This is more common than you might expect. When asked what their personal responsibilities are under the OH&S management system, some senior managers will refer you to the safety team or the safety manager. That response is a red flag. Clause 5.1 is explicit that top management bears overall accountability. If they cannot articulate what that means in practice, you have a finding.

The nonconformity here is not that they lack a job description. It is that there is no evidence of genuine ownership of the OH&S management system at the top management level.

Resources Are Not Being Provided

One of the clearest indicators of leadership commitment is resource allocation. If the safety function is chronically understaffed, if training budgets are consistently cut, or if OH&S improvement projects are repeatedly deferred due to cost, these patterns suggest that safety is not genuinely integrated into business decision-making.

Ask to see the budget allocated to OH&S activities. Ask whether there have been requests for resources that were declined, and if so, how those decisions were made. Compare the stated OH&S objectives with the resources allocated to achieve them. Misalignment between ambition and resourcing is a reliable indicator of shallow commitment.

Safety Culture Is Not Supported From the Top

Clause 5.1 specifically requires top management to develop, lead, and promote a culture that supports the intended outcomes of the OH&S management system. This is one of the most difficult requirements to audit, but it is not impossible.

Triangulate your evidence. Talk to workers and ask them whether they feel safe raising concerns. Review incident and near-miss reporting rates. Low reporting rates in a high-hazard environment often indicate that workers do not trust the reporting process, which is a cultural indicator. Check whether there have been any instances of workers being disciplined or penalised after reporting a safety concern. That would be a direct breach of the requirement to protect workers from reprisals.

For a broader understanding of how auditors assess OH&S systems under ISO 45001, the article on auditing occupational health and safety under ISO 45001 provides useful context for how Clause 5.1 connects to the rest of the standard.

OH&S Is Not Integrated Into Business Processes

Integration is one of the most frequently misunderstood requirements in Clause 5.1. Organisations often interpret it as meaning they have a safety management system that runs alongside their business. The standard requires something more: OH&S requirements must be embedded into the organisation's core business processes.

Look for evidence of integration in procurement decisions, project planning, contractor management, and change management. Ask whether OH&S risks are considered when new contracts are won, new equipment is purchased, or new processes are introduced. If safety considerations only enter the picture after a decision has already been made, integration is not happening.

Worker Consultation Is Nominal Rather Than Genuine

Clause 5.1 requires top management to ensure processes for worker consultation and participation are established and implemented. This connects directly to Clause 5.4, but the leadership obligation sits in Clause 5.1.

Check whether safety committees exist and whether they function. Review the minutes. Are workers raising issues? Are those issues being resolved? Are workers from different levels and functions represented? If the committee is dominated by management voices and worker concerns are consistently deferred or dismissed, the consultation process is not genuine.

Writing Findings Against Clause 5.1

Findings against leadership commitment clauses require careful writing. You are making a finding against senior people in the organisation, and your evidence must be solid. Vague findings like “management does not appear committed to safety” will not hold up. You need specific, factual, evidence-based statements.

A well-written finding against Clause 5.1 might read: “During the audit, top management was unable to describe their personal OH&S responsibilities or provide examples of decisions made in the past twelve months that reflected OH&S considerations. The management review records for the current year contain no evidence of resource allocation decisions related to OH&S objectives. This does not demonstrate the accountability required by Clause 5.1 of ISO 45001:2018.”

That finding is specific, evidenced, and referenced to the standard. It tells the auditee exactly what was found and why it is a nonconformity. For more guidance on writing findings that hold up to scrutiny, the article on how to write audit findings that stand up to challenge is worth reading before you start drafting.

Distinguishing Between a Minor and Major Nonconformity

When you find gaps in leadership commitment, you need to make a judgement about severity. A single manager who cannot recall a specific example of a recent safety decision is a minor issue if the broader evidence suggests genuine engagement. A pattern of evidence showing that top management has effectively outsourced all safety responsibility to the safety team, that resources are not being provided, and that workers are afraid to report hazards, is a major nonconformity.

The key question is whether the gap affects the ability of the OH&S management system to achieve its intended outcomes. If leadership is genuinely absent from the system, the system cannot function as intended. That is a major finding. If leadership is broadly engaged but there are isolated gaps in specific requirements, those are likely minor findings.

Preparing for a Clause 5.1 Audit as the Quality or Safety Manager

If you are a safety manager preparing your organisation for an internal or certification audit of Clause 5.1, your job is to help top management understand what is expected of them before the auditor arrives. That means briefing them on the specific requirements, not just handing them a copy of the standard.

Prepare your top managers to answer questions about their personal involvement in the OH&S system. Collect evidence of their engagement: emails directing safety improvements, budget decisions that prioritised OH&S, attendance at safety committee meetings, participation in incident investigations. These records will support your audit.

Make sure your management review records are current and substantive. If the last management review was held over a year ago, or if the minutes are two paragraphs long with no action items, address that before the audit. The management review is one of the first places an auditor will look when assessing leadership commitment.

How Auditor Training Prepares You for Leadership Audits

Auditing leadership commitment is a skill that takes practice. It requires confidence in interviewing senior people, the ability to triangulate evidence from multiple sources, and the judgement to distinguish genuine commitment from performance. These are not skills you develop by reading the standard. They come from structured training and supervised practice.

At Audit Workshop, the ISO 45001 Internal Auditor and Lead Auditor courses cover Clause 5.1 in practical depth. You will work through real audit scenarios, practice interview techniques with experienced facilitators, and learn how to write findings against leadership requirements that will hold up under scrutiny. The courses are delivered by Dilawar Laghari, a certified lead auditor with over 500 external ISO certification audits across Australia and internationally, including extensive experience auditing OH&S management systems in high-hazard industries.

If you are preparing to audit leadership commitment for the first time, or if you want to sharpen your approach to Clause 5.1, the ISO 45001 training programmes at Audit Workshop will give you the practical foundation you need.
