ISO 45001:2018

WHAT IS ISO 45001:2018?

ISO 45001 is the ISO international standard that replaced the previous OHSMS 18001 standard. The main reason for the change was to provide greater scope to cover anyone with links to the company, along with better risk management, a better workplace, and to change the hazard identification process approach.

Why should I get the Certification?

Your organisation's human capital is its greatest asset, meaning that the health and well-being of your employees is one of the key aspects of your business' success, irrespective of its activity and size. Accidents and stressful situations have a negative impact on your organisation's performance, both in terms of output, through sick leave and absenteeism, and reputation.

There are also some very important strategic aspects that your company should consider:


High Level Structure integration

High Level Structure (HLS) is a standardised approach to drafting future ISO management system standards. It is defined in Appendix SL of the ISO/IEC Directives, Part 1. All new standards should observe and share a common and consistent core:

  • A common general structure: whereby chapters, article numbers, and chapter, article, or clause titles, etc.
  • Identical wording for identical requirements
  • Common terms and core definitions

ISO 45001 was prepared using High Level Structure (HLS). This unified structure gave ISO 45001 a common and consistent core in line with other updated standards, such as ISO 9001:2015 and ISO 14001:2015. Other new aspects compared to its predecessor, OHSAS 18001, include:

1 A new approach to risk definition
A review of the concept of the workplace and the worker 2
3 More understandable language for the services sector, referring to risk identification and risk control, instead of hazards
Safety Management extends to every operation in the organisation through Management Leadership and employee participation 4
5 The assessment requirement was extended to comply with legal requirements
It introduces new concepts such as occupational well-being, risk, and opportunities 6
7 The context of the organisation and stakeholder expectations are of particular importance
