ISO 45001 Occupational Health and Safety Management System
We build Annex SL aligned occupational health and safety management that reaches past compliance into genuine worker participation and clear risk thinking
ISO 45001 Occupational Health
and Safety Management System
ISO 45001 2018 replaced OHSAS 18001 with an Annex SL high level structure shared with ISO 9001 and ISO 14001, and that shared structure lets you run integrated management systems while it raises the practical bar a great deal. The standard introduced four substantive changes that our team works through with your people. It made plan do check act with risk based thinking explicit. It asked for demonstrable leadership and worker participation evidence under clauses 5.1 and 5.4. It called for interested party and context analysis under clauses 4.1 and 4.2. And it tightened outsourced process control under clause 8.1.4. Migration from OHSAS 18001 closed in March 2021 and more than 100,000 organisations now hold certification, yet real world maturity remains uneven. Common Stage 2 findings cluster around hazard identification across non routine and contractor activities, around worker participation that is real rather than token, around the currency of the legal and other requirements register, and around the operational control of outsourced activity. We integrate the system with the HSE HSG 65 plan do check act model, with CCPS RBPS for your high hazard sites, and increasingly with ISO 45003 psychological health and safety for office and shift work settings.
ISO 45001 Occupational Health and Safety Management System element by element
Each element below has its own dedicated implementation page with focused methodology, flow chart, and individual significance for organisations. Click any element to explore.
We establish your internal and external context, your interested parties and the scope of your occupational health and safety management system
We build top management commitment, your health and safety policy, clear roles and genuine consultation and participation of workers
We drive hazard identification, risk assessment, legal compliance and clear health and safety objectives
We provide the resources, competence, awareness, communication and documented information your management system depends on
We deliver operational planning and control, the hierarchy of controls, management of change, procurement, contractor management and emergency preparedness
We run monitoring, measurement and analysis, the internal audit and the management review
We turn incidents, non conformities and corrective action into genuine continual improvement
How the system is implemented
A structured, facilitated process that runs from scope definition through close out and produces defensible, actionable outputs.
Conduct clause by clause ISO 45001 2018 gap assessment against current OHSMS or OHSAS 18001 documentation, execute PESTLE style context analysis per Cl.4.1, map interested parties and their OH&S relevant requirements per Cl.4.2, scope the OHSMS and determine organisational boundaries per Cl.4.3.
Build comprehensive hazard identification covering routine, non routine, emergency, and outsourced activities per Cl.6.1.2 (IEC 45001's substantially higher bar than OHSAS 18001), classify risks using the elimination/substitution/engineering/admin/PPE hierarchy per Cl.8.1.2, document opportunity and risk register per Cl.6.1.1.
Build legal and other requirements register with applicability tagging, currency dates, and evidence traceability per Cl.6.1.3, design worker participation framework per Cl.5.4 with documented mechanisms beyond consultation tokenism, implement OH&S objectives with monitoring plan per Cl.6.2.
Develop emergency preparedness and response procedures per Cl.8.2 with drill schedule and learning capture, implement outsourced process control per Cl.8.1.4 covering contractor pre qualification, site induction, work control, and performance review, integrate ISO 45003 psychological H&S and fatigue risk management.
Establish internal audit programme per ISO 19011 with competency requirements, sampling plan, and finding triage, configure TRIR / LTIFR / near miss / leading indicator dashboard, implement management review agenda per Cl.9.3 with input/output requirements and corrective action escalation path.
Conduct pre certification desktop readiness review addressing top Stage 1 nonconformity patterns, perform Stage 2 trial audit against accredited certification criteria, produce corrective action evidence packs for typical Cl.5.4 (worker participation), Cl.6.1.2 (non routine hazards), and Cl.8.1.4 (outsourced process) findings.
What the system covers in full
Outcomes of ISO 45001 Occupational Health and Safety Management System
- We close the systemic gap between the paper system and shop floor reality
- We drive worker participation discipline that surfaces field level hazards
- We tighten oversight of contractor and outsourced activity
- We embed psychological health and safety risk through ISO 45003 integration
- We earn ISO 45001 2018 certification that holds firm through accredited Stage 2 examination
- We align the system with India BOCW and the Factories Act, with OSHA and with the EU OSH Framework Directive 89 391
