ISO 45001 Occupational Health & Safety Management System Certification

Improve the occupational health and safety (OH&S) of both employees and other personnel

Improve the occupational health and safety (OH&S)

What is ISO 45001 Occupational Health and Safety (OH&S)?

ISO 45001 is an international standard that specifies requirements for an Occupational Health & Safety Management System OHSMS, which is intended to improve the safety and health of both employees and other personnel.

Introduced in March 2018, ISO 45001 marks a significant step forward in the overall effort to improve occupational health and safety (OH&S) worldwide. Published by the International Organization for Standardization (ISO), the standard enables organisations to proactively improve injury prevention and reduce ill-health, while protecting their longevity.

ISO 45001 management system supersedes previous occupational health and safety (OHS) standards, including OHSAS 18001. Download our complimentary whitepaper to learn more about the transition from OHSAS 18001 to ISO 45001 certification and its requirements.

To survive in today’s competitive global marketplace, organisations must proactively manage all types of risk to the business, and the issue of occupational health and safety is no exception. ISO 45001 will provide new impetus for occupational health and safety practices in organisations and will help improve safety for employees and contractors. This translates into additional opportunities for protecting and promoting worker’s health and performance, as well as a sustainable improvement of employee motivation.

Key features of the ISO 45001 OH&S standard

Although ISO 45001 Occupational Health & Safety constitutes a fully new standard, its foundations already exist and are formulated in OHSAS 18001. Companies that have already implemented an occupational health and safety management system OHSMS in accordance with OHSAS 18001, and actively apply it in everyday company practice, can expect a smooth transition to ISO 45001 certification and achieve ISO 45001 compliance.

Key improvements:

  • ISO 45001 Occupational Health & Safety Management System implements the ‘high level structure’, giving it a common framework with other management systems, such as ISO 9001 Quality Management System and ISO 14001 Environmental Management System
  • ISO 45001 OHSMS places great emphasis on the responsibility of senior management. This aspect has already been implemented in the revised ISO 9001 QMS and ISO 14001 EMS standards.
  • ISO 45001 OHSMS explicitly includes persons who are not permanently employed, but are in other ways working under the responsibility of the organisation/company, such as subcontractors, as well as processes that have been outsourced in their entirety. In this way it incorporates elements of the SCC certificate.
  • The standard also introduces the term “opportunities”, as a new aspect in the field of occupational health and safety OHS This covers issues that go beyond the mere elimination or minimisation of OHS risks and hazards.
