OHSAS 18001

OHSAS 18001:2007

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.


  • Identify workplace hazards and implement effective preventive controls 
  • Prevent injury and ill-health among your workforce
  • Reduce lost time accidents therefore cost saving 
  • Evaluation of  compliance with legislative requirements
  • Improves the safety culture
  • Identify areas for training and competency requirements
  • Improve productivity 
  • Assist with pre-qualification processes from your customers 
  • Promote corporate responsibility



It’s right if you and your organization want to eliminate or minimize risk to anyone who may be exposed to health and safety risks associated with your activities.

Organisations that implement OHSAS 18001 need a clear management structure with defined authority and responsibility. Clear objectives for improvementare required, with measurable results and a structuredapproach to risk assessment. This includes monitoring health and safety management failures, auditing performance and reviewing policies and objectives.

  • 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.

Application for registration is made by completing the OHSAS 18001 Quote Request Form. This provides information about your organisation so we can accurately define the scope of assessment.

Assessment to OHSAS 18001 is undertaken by NQA - this consists of two mandatory visits that form the Initial Certification Audit (explained below). Please note that you must be able to demonstrate that your management system has been fully operational for a minimum of three months and has been subject to a management review and full cycle of internal audits.

Certification to OHSAS 18001 is issued by NQA and maintained through a programme of annual surveillance audits and a three yearly recertification audit.

For further information on the audit stages.

ISO 45001 is the future replacement to OHSAS 18001 and will become the ISO standard for Occupational Health and Safety Management Systems (OHSMS).

Not only will the standard supercede OHSAS 18001, it will make integration with other management systems simpler than ever before; because it shares the new common structure defined by Annex SL, it is directly aligned with the 2015 versions of ISO 9001 and ISO 14001. 

If you have certification to OHSAS 18001 you will need to migrate to ISO 45001 to maintain the validity of certification.

ISO 45001 is expected to be published in the first half of 2018, so there is plenty of time to plan the migration.​
