ISO 45001:2018
Occupational Health & Safety Management System (OHSMS)
ISO 45001:2018 is the world's first international standard specifically focused on Occupational Health and Safety (OHS) management systems. It replaced OHSAS 18001 in 2021. The standard provides a framework to increase safety, reduce workplace risks, and improve employee health and wellbeing. ISO 45001 takes a proactive approach — preventing harm before it occurs rather than reacting after incidents. With over 50,000 certificates globally and growing, it is rapidly becoming the international benchmark for workplace safety.

Scope of Application
Applicable to any organization that wishes to establish, implement, maintain, and improve an occupational health and safety management system. Particularly essential for high-risk sectors: manufacturing, construction, mining, chemicals, oil & gas, and large factories.
Key Principles
- Worker participation — employees actively involved in OHS system
- Hazard identification and proactive risk elimination
- Legal and regulatory OHS compliance (Factories Act, Mines Act, etc.)
- Hierarchy of controls: Eliminate → Substitute → Engineering → Administrative → PPE
- Incident investigation and learning from near-misses
- Emergency preparedness and response readiness
- Continual improvement of OHS performance
