What is ISO 45001:2018?
ISO 45001:2018 is the international standard for Occupational Health and Safety Management Systems (OH&S MS). It replaced OHSAS 18001 and provides a framework for organisations to proactively improve worker safety, reduce workplace risks, and create better working conditions.
Why ISO 45001 Matters for South African Businesses
South Africa's regulatory environment — governed by the OHS Act (Act 85 of 1993) — sets the baseline. ISO 45001 goes further by establishing a systematic, internationally recognised management system that:
- Reduces workplace incidents by 40-60% on average
- Lowers workers' compensation costs significantly
- Satisfies tender requirements — many government and private sector tenders now require ISO 45001
- Demonstrates due diligence — strengthens your legal defence under Section 37 of the OHS Act
- Improves BEE scoring — management systems contribute to enterprise development
- Enables international trade — essential for companies exporting or working with multinationals
ISO 45001 vs OHSAS 18001: Key Differences
| Feature | OHSAS 18001 | ISO 45001:2018 |
|---|---|---|
| Structure | Standalone | Annex SL (integrates with ISO 9001, ISO 14001) |
| Leadership | Management representative | Top management accountability |
| Worker participation | Consultation | Active participation required |
| Risk approach | Hazard-based | Risk and opportunity-based thinking |
| Context | Not required | Understanding internal/external context |
| Outsourcing | Limited coverage | Full supply chain consideration |
| Status | Withdrawn (March 2021) | Current international standard |
If you still hold OHSAS 18001, you need to transition immediately — the standard has been withdrawn and is no longer recognised by accredited certification bodies.
