-Purpose of the standard remains the same; many of the topics covered in the OHSAS 18001 are provided in the current ISO/DIS 45001.
-The new standard will follow the new format "High-Level Structure" of Annex SL, the new ISO (HLS) that introduces a mutual framework to all management systems. Which means it will be aligned with the revised versions of ISO 14001 and ISO 9001.
- In the new standard, there is a greater focus on the environment in which the organization operates, as well as a greater role assigned to the top management.
-Easier integration with other standards since the structure (HLS) will be identical. Easier integration with ISO 14001, since many organizations, especially small ones, assign a person who follows both aspects of environmental and OH&S security because they are commonly considered as related areas.
-ISO 45001:2016 standard provides additional focus on process approach, and clarifies why it is essential to implement it in each business process of the organization.
-The 45001 will maintain the same commitments of 18001 to regulatory compliance, but strengthening the basic concepts.
- Leadership and culture: Specific requirements for top management in terms of demonstrating leadership, commitment and encouraging a positive occupational health and safety culture within the organization.
-Documentation flexibility
-Greater Importance on Hierarchy of controls
-Proactive strategic approach
-ISO 45001 focuses on identifying and controlling risks, rather than hazards, as it is required in OHSAS 18001.
-Some of the terminology will use similar approaches of other management systems while also maintaining a different specialized approach on OH&S management system.
-Risk-based thinking is one of the major changes in ISO 45001 compared to OHSAS 18001. It requires from organizations to consider the risks and opportunities associated with the issues that are identified in clause 4.1, more specifically with regards to the interested parties. This clause has brought a significant change to the standard, by replacing preventive actions and reducing the need for corrective actions.
-Better focus on stakeholders is another change in ISO 45001:2016. The general requirement (clause 4.1) of OHSAS 18001 is also incorporated into the ISO 45001, but the changes that are made are put into two new sub-clauses: “Understanding the organization and its context†and “Understanding the needs and expectation of interested partiesâ€.
-Integration of Annex SL as a foundation in the new ISO 45001 standard – the new ISO high- level structure (HLS) means that in comparison with the 18001, the structure of the new ISO 45001 standard will be as follows:
*Scope
*Normative references
*Terms and definitions
*Context of the organization
*Leadership
*Planning
*Support
*Operation
*Performance evaluation
*Improvement
The first major change thus is that there are now ten sections instead of four as they were in OHSAS 18001.
