ISO 45001 is a global standard for Occupational Health and Safety that provides everyday solutions for worker safety. Health and safety in the workplace is a major concern for most businesses, yet several deaths and injuries occur.

This Standard lays the foundation for worker safety standards that can be used by all global supply chains, industries and cover contractors and subcontractors in every country that supply products into these supply chains.


The Occupational Health and Safety Management Systems ISO 45001 was developed by ISO’s Project Committee ISO/PC 283. After a 5 year development period the standard was released on 12th March 2018. This standard defines good practices in OH&S management and specifies requirements for a management system.

In developing the standard, consideration has been given to the content of other international standards (such as OHSAS 18001 or the International Labour Organisation’s “ILO –OSH Guidelines”) and national standards, as well as to the ILO’s International Labour standards and conventions (ILSs).

WHAT IS ISO 45001?

The ISO 45001 standard is applicable to all organizations, regardless of size, industry or nature of business. All organizations, public or private, for-profit and not-for-profit, small or large, will have hazards that can impact on health and safety. These can range from the more traditional items of mechanical or chemical hazards, to more modern issues such as the risks from nanoparticles or workplace stress.

It is designed to be integrated into an organization’s existing management processes and follows the same high-level structure as other ISO management system standards, such as ISO9001 (quality management) and ISO14001 (environmental management)

KEY BENEFITS of Occupational Health and Safety Management System(OH&S) ISO 45001

An ISO 45001 based OH&S management system will enable an organization to improve its OH&S performance by:

  • developing and implementing an OH&S policy and OH&S objectives
  • establishing systematic processes which consider its “ context ” and which take into account its risks and opportunities, and its legal requirements and other requirements
  • determining the hazards and OH&S risks associated with its activities; seeking to eliminate them, or putting in controls to minimize their potential effects
  • establishing operational controls to manage its OH&S risks and its legal requirements and other requirements
  • increasing awareness of its OH&S risks
  • evaluating its OH&S performance and seeking to improve it, through taking appropriate actions
  • ensuring workers take an active role in OH&S matters

In combination these measures will ensure that an organization’s reputation as a safe place to work will be promoted, and can have more direct benefits, such as:

  • improving its ability to respond to regulatory compliance issues
  • reducing the overall costs of incidents
  • reducing downtime and the costs of disruption to operations
  • reducing the cost of insurance premiums
  • improving morale, as well as reducing absenteeism and employee turnover rates
  • recognition for having achieved an international benchmark (which may in turn influence other interested parties, such as customers who are concerned about their social responsibilities)

What are the major differences between OHSAS 18001 and ISO 45001?

There are many differences, but the main change is that ISO 45001 concentrates on the interaction between an organization and its business environment while OHSAS 18001 was focused on managing OH&S hazards and other internal issues. But the standards also diverge in many other ways:

  • ISO 45001 is process-based – OHSAS 18001 is procedure-based
  • ISO 45001 is dynamic in all clauses – OHSAS 18001 is not
  • ISO 45001 considers both risk and opportunities – OHSAS 18001 deals exclusively with risk
  • ISO 45001 includes the views of interested parties – OHSAS 18001 does not

These points represent a significant shift in the way health and safety management is perceived. OH&S is no longer treated as a “stand alone”, but must be viewed within the perspective of running a sound and sustainable organization. That being said, although the two standards differ in their approach, a management system established in accordance with OHSAS 18001 will be a solid platform for migrating to ISO 45001.

Validity of Accredited Certifications to OHSAS 18001:2007

Companies certified to OHSAS 18001:2007 will have three years to migrate to ISO 45001:2018. By March 2021, OHSAS 18001 certified companies have to complete their migration.
