ISO 9001 vs 14001 vs 45001. What's the difference?
They share the same backbone, so they look alike, but each protects something different. ISO 9001 protects the customer, ISO 14001 protects the environment, and ISO 45001 protects the worker.
Same structure, different purpose.
All three follow the Annex SL structure and share most of their requirements. The difference is what each one is actually about, and that is what an auditor tests.
ISO 9001: Quality
Consistently meeting customer requirements and improving satisfaction: customer focus, process and product control, and handling nonconforming output.
ISO 14001: Environment
Managing environmental responsibility: environmental aspects and impacts, compliance obligations, and prevention of pollution.
ISO 45001: Health & Safety
Preventing work-related injury and ill health: hazard identification and risk assessment (HIRA), worker participation and OH&S controls.
What they share
Leadership, risk-based thinking, document control, competence, internal audit, management review, non-conformance and continual improvement, all common ground.
Same backbone, different job.
Tap a standard to focus it. Each protects something different; the rest of the system they share.
All three share one Annex SL backbone (leadership, risk, document control, audit, review and improvement) so iQuotient runs them (plus ISO 27001) as one system, each keeping its own scope and evidence.
Run them together, plus ISO 27001.
Because the shared requirements only need to exist once, iQuotient runs ISO 9001, 14001 and 45001 (and 27001 for information security) on one Annex SL backbone, each keeping its own scope, evidence and audit trail.
