ISO 45001:2018 is the first international standard specifying requirements for an occupational health and safety management system, replacing the British OHSAS 18001 that organizations worldwide had previously referenced. The standard has since received a 2024 amendment on climate action and is currently under review at Draft International Standard stage, with a major revision expected in the coming years.
Why Thai Organizations Should Prioritize This
Workplace accident statistics in Thailand remain a concern, particularly in manufacturing and construction. The cost of an accident is not limited to medical expenses or compensation — it also includes lost production time, employee morale, and reputational damage with business partners. ISO 45001 helps organizations manage these risks systematically, rather than reacting only after an incident occurs.
A Structure Connected to Other Management Standards
Because ISO 45001 shares the same High Level Structure under Annex SL as ISO 9001 and ISO 14001, organizations that already operate a quality or environmental management system can integrate a safety management system efficiently, reducing duplicated documentation and audits.
A Recommended Starting Point
Organizations should first understand their own legal context — particularly Thailand's Occupational Safety, Health and Environment Act — and then connect that understanding to the hazard identification and risk assessment process required by the international standard, so the resulting system satisfies both legal and international requirements at once.
