About the standard
What it is
ISO 45001 helps organisations prevent work-related injury and ill health, provide safe and healthy workplaces, and involve workers in health and safety. It replaced the British standard OHSAS 18001 — sometimes wrongly called “ISO 18001”.
If you still have OHSAS 18001-based documents, we can convert them to ISO 45001.
What the draft revision focuses on
- Psychosocial risks — mental health, stress and workplace culture
- Climate-related effects on workers, such as heat stress and extreme weather
- Worker diversity and different needs in risk management
- Encouraging reporting of incidents, hazards and opportunities
- Continued alignment with the Harmonized Structure
The revision is still a draft and may change. Keep maintaining ISO 45001:2018 — it remains the certifiable standard until the new edition is published.
