Clarifying the Purpose of an ISO 45001 Audit Checklist

• A good ISO 45001 audit checklist serves to:

  1. Clarify audit scope and objectives (e.g., hazard identification, performance evaluation).

  2. Provide structured questions around clauses such as risk assessment, leadership, planning, operation, performance evaluation, and improvement.

  3. Act as a reference point during audits for both compliance and improvement.

How to Build an Effective iso 45001 audit checklist (Step-by-Step)

Building an effective ISO 45001 audit checklist requires a structured approach that aligns with the standard’s clauses while remaining practical for your organisation’s operations. Follow these steps to ensure your checklist is both compliant and easy to use:

1. Understand the Standard

   • Review ISO 45001:2018 in detail, focusing on clause requirements.

   • Pay special attention to occupational health and safety obligations, such as hazard identification, worker participation, and continual improvement.

2. Break Down Clauses into Auditable Questions

   • Convert each clause into clear, actionable questions.

   • For example: “Has the organisation identified internal and external OH&S risks?” or “Is there a documented process for incident investigation?”

3. Group Questions by Process Area

   • Organise them into sections like Context, Leadership, Planning, Support, Operation, Performance Evaluation, and Improvement.

   • This makes it easier to cover all areas systematically during the audit.

4. Include Evidence Requirements

   • Add a column for “Notes/Evidence” so auditors can record supporting documents, observations, or interview responses.

   • This ensures traceability and supports future follow-up.

5. Use a Status or Rating System

   • Include fields such as Yes/No/N/A or scoring criteria to indicate compliance levels.

   • This makes it easier to analyse results and identify trends.

6. Customise for Your Industry

   • Add sector-specific items, such as machinery safety for manufacturing, PPE compliance for construction, or chemical handling for laboratories.

7. Review and Update Regularly

   • Audit checklists should be living documents—update them when processes, legal requirements, or the ISO 45001 standard changes.

8. Train Your Audit Team

   • Provide training on how to interpret checklist questions, gather evidence, and assess compliance consistently.

By following these steps, you create a practical and reliable ISO 45001 audit checklist that guides auditors, ensures compliance, and drives continual improvement.

This table offers clarity in building or using an ISO 45001 audit checklist effectively.

Customising Your Checklist: Industry-Specific Considerations

• Manufacturing – include machinery risk assessments, permit-to-work, lockout/tagout.

• Construction – emphasise PPE usage, site inductions, fall protection, subcontractor safety.

• Healthcare or Laboratory – incorporate infection control, ergonomic hazards, chemical safety.
  Use keywords like OH&S management system audit and risk assessment audit ISO 45001 to tailor for real-world searches. Customisation ensures the checklist remains practical across sectors.

 Top Tips to Ensure Your Checklist Aligns with ISO 45001:2018

1. Use exact clause numbering and terminology.

2. Keep it concise yet comprehensive.

3. Use clear Yes/No/N/A status fields and space for notes/evidence.

4. Update regularly to reflect process changes or legal updates.

5. Use digital formats where possible for easier tracking and audit trail.

6. Train your auditors to ensure consistent application.
   Keywords such as ISO 45001 audit preparation, internal audit tool for ISO 45001, and OH&S audit template naturally fit here to meet user searches.

 Common Pitfalls in Audit Checklists and How to Avoid Them

• Too generic – avoid vague items like “complies with policy” without specifics.

• Too long – users may ignore or rush through.

• No linkage to evidence – always add “Notes/Evidence” column.

• Missed clause updates – ensure alignment with ISO 45001:2018.

• Ignoring worker input – explicitly include worker perspectives under Clause 5. Use terms like ISO 45001 internal audit checklist and risk assessment audit ISO 45001 to reinforce specificity.

How to Use Audit Findings to Drive Corrective Action

• Summarise findings immediately into an action register.

• Categorise findings: critical, major, minor.

• Assign responsibilities and due dates.

• Follow up and verify completion.

• Feed insights into continual improvement and OH&S performance reviews.
  This process links ISO 45001 audit checklist directly to corrective measures and improvement—crucial for real-world value.

Integrating Your Audit Checklist Within an Integrated Management System (IMS)

• If you’re using ISO 9001 or ISO 14001, align audit checklists to reduce duplication.

• Create combined sections for shared clauses (e.g., leadership, support).

• Use a central digital platform IMS to track multiple standards together.
  This approach supports keyword synergy: ISO 45001 internal audit checklist, ISO 45001 compliance checklist, and integrated audit checklist.
