The ISO 45001 standard was published to supersede OHSAS 18001. Companies already certified to OHSAS 18001 will have 3 years to become certified to the new ISO 45001:2018 standard.

ISO 45001:2018 applies to the ISO High-Level Structure and is compatible with ISO 9001:2015 and ISO 14001:2015. Therefore, it can be integrated into these Management Systems.

Differences within the revised Standard include:

Context of Organisation
Referring to the External and Internal Issues within their environment. This is methodically determined and monitored. It also includes the circumstances affecting operations, such as regulations, stakeholders, and governance.

Needs and Expectations of Workers
Needs and expectations of employees and other interested parties such as customers, board members, and stakeholders are defined.

Risks and Opportunities
Determine the risks and opportunities that may impact the Company’s ability to deliver planned results. This includes employee health and safety enhancements, as well as legal and other requirements.

Leadership
Management and all employees of a Company must be engaged with and responsible for the Management System.

Objectives and Performance Reviews
Increased focus on the objectives determined by the Company and evaluated during performance review. Objectives should support Company Policies. Achieving objectives within the allotted timeframes and measures to establish progress must be definite and should evaluate whether objectives have been reached.

ISO 22000:2018 is an international standard that follows the same high-level structure as other widely applied ISO standards, such as ISO 9001 and ISO 14001. Therefore, it is easy to integrate within other Management Systems.

If you are ISO 22000:2005 compliant, you will comply with most of the requirements in ISO 22000:2018. However, there are some changes from ISO 22000:2005 that you must prepare for to comply with ISO 22000:2018.

Differences within the revised Standard include:

• Business context and interested parties.
• Strengthened importance on leadership and management commitment.

ISO 22301:2019 follows a similar approach as other ISO Management Systems such as ISO 9001 and ISO 27001, with less strict requirements.

ISO 22301:2019 gives greater flexibility in developing a management system and increased confidence in changing such a Management System.

Differences within the revised Standard include:

• Resources are identified based on solutions.
• Changes within the Management System must consider purpose, consequences, responsibilities, integrity, and resources.
• Impact types and context-relevant criteria are mandatory for Business Impact Applications (BIA).
• Documents define solutions to handle specific risks and impacts relevant to continuity.
• All changes in the Management System are done in a planned manner.
• There is greater flexibility and practicality to achieve results.
