ISO 45001 — Work Health & Safety
Protect your people. Meet your legal obligations. Win more work.
ISO 45001:2018 is the international standard for occupational health and safety management systems. It provides a framework for preventing work-related injuries and illnesses by proactively identifying and managing workplace risks.
For businesses operating in Defence, construction, manufacturing, and transport, ISO 45001 demonstrates a serious commitment to the safety of your workers — and is increasingly required for pre-qualification and tendering.
What ISO 45001 covers:
| Hazard identification and risk assessment |
| Worker consultation and participation |
| Operational controls for high-risk activities |
| Incident investigation and corrective actions |
| Legal compliance and due diligence obligations |
| Emergency preparedness |
