OHSAS 18001 Health & Safety Certification | NQA

OHSAS 18001 is the International Standard for Health and Safety Management Systems.


OHSAS 18001 is the International Occupational Health and Safety Management Standard. It provides a framework for the effective management of OH&S including all aspects of risk management and legal compliance. It addresses occupational health and safety rather than any specific product safety matters.

Please note: OHSAS 18001 is due to be replaced by ISO 45001, the new international standard for occupational health and safety management systems (OHSMS). You can still apply for certification to OHSAS 18001, but more information on the migration to ISO 45001 is available here.

  • Prevent injury and ill-health among your workforce

OHSAS 18001 is right for over 90,000 certified organizations in over 127 countries around the world. It’s right if you and your organization need to show ‘best practice’ in managing the safety of people it is responsible for.

NQA has certified a wide range of organizations in different sectors including Jaguar Land Rover and Veolia Water. 

Biffa’s NQA certified OHSAS 18001 system helped Matthew Humphreys (Head of Safety, Health & Quality, Biffa), to achieve a 40% reduction in serious incident levels, plus significant cost savings from fewer lost time incidents year on year.

Organizations that implement OHSAS 18001 need:

  • a clear management structure with defined authority and responsibility.
  • defined objectives for improvement, with measurable results
  • a structured approach to risk assessment.

Health & safety management failures, performance and the review of policies and objectives should be regularly monitored to ensure improvements and business benefits are realised and prioritised accordingly.

“NQA stood out in their level of understanding and knowledge of Jaguar Land Rover’s business and the implications for Health and Safety within the organization.” Jaguar Land Rover


  • Customer satisfaction. Meet customer requirements consistently whilst safeguarding their health and property.

  • Reduced operating costs. Less down-time due to incidents and ill health and lower costs from legal fees and compensation means money saved.

  • Improved stakeholder relationships. Make the health and property of staff, customers and suppliers more of a priority and people will respond.

  • Legal compliance. Understand how statutory and regulatory requirements impact your organization and its customers.

  • Improved risk management. Identify potential incidents and implement controls and measures to keep risk as low as possible.

  • Proven business credentials. Independent verification against recognized standards speaks volumes.

  • Win more business. Procurement specifications often require certification as a condition to supply so gaining the standard opens doors. OHSAS 18001 is also recognised by Safety Schemes In Procurement (SSIP).

“The fact that an authoritative and independent auditor visits the sites and checks the processes is a really important signal to the staff of how important the health and safety systems are to the company.” Veolia Water
