What’s New

To help you understand what is new and what has changed between AS/NZS 4801:20001 and ISO/DIS 45001:2016 (DIS = Draft International Standard) we have compared both Standards to highlight key changes.

New Requirements
ISO 45001 introduces a small number of requirements that are largely new when compared to AS/NZS 4801:2001, including:

  • Understanding the Organisation and its context (4.1)
  • Understanding the needs and expectations of workers and other interested parties (4.2)
  • Assessment of risks to the OH&S Management System (
  • Identification of OH&S opportunities (
  • Planning to take action (6.1.4)
  • Evaluation of compliance with legal and other requirements (9.1.2)

Consolidated Requirements
ISO/DIS 45001:2016 consolidates a requirements spread across a number of clauses of AS/NZS 4801 into stand-alone requirements including (AS/NZS clause numbers in brackets). For example:

  • Management of Change (4.3.4, 4.4.3,, 4.5.2)
  • Outsourcing, Procurement  and Contractors (4.3.1, 4.3.2, and 4.4.2,
  • Continual Improvement  (4.2, 4.3.3,,

Modified Requirements
ISO/DIS 45001:2016 clauses represent a modification of what is required in AS/NZS 4801 rather than being a totally new requirement. For example:

  • OH&S Policy (5.2)
  • Participation and consultation (5.4)
  • Emergency preparedness and response (8.2)
  • Continual improvement (10.2)

Relocated Requirements
ISO/DIS 45001 is based on a 1-10 Section structure. Accordingly, ISO 45001 simply relocates a requirement that is very similar to a requirement in AS/NZS 4801:2001.

​For example:


What’s Familiar


Thankfully, ISO have not recreated the wheel. 

If you  are familiar with AS/NZS 4801:2001 you will be familiar with many of the requirements and concepts in ISO/DIS 45001:2016, including:

  • The Plan-Do-Check-Act model remains the fundamental “systems” model promoted by ISO 45001.

  • Process Approach – establishing a Policy and objectives for improvement and processes to achieve them, implementing these processes and monitoring and measuring process results remains a key part of the Standard.
  • The overall intent (a framework for managing prevention of death, injury, ill-health) is consistent with AS/NZS 4801:2001.
  • ISO 45001 maintains (and enhances) the focus on the role of top management in an effective OH&S management system
  • ISO 45001 maintains a strong focus on hazard, risk, controls focus
  • Very similar requirements for:

           – Planning and policy
           – Legal requirements
           – Improvement – objectives, action planning, monitoring.
           – Awareness, consultation, competency needed
           – Resources required to support system
           -Monitoring, evaluating, analysing OHS performance and improvement.
