Helps you with

Accident Management, Legal Compliance, Culture Change, Training and Competence, Corporate Responsibility, Productivity, Pre-Qualification, Risk Assessment, Workplace Hazards

Note: This information relates to the 2007 version of OHSAS 18001 which is to be superseded by ISO 45001 - this is expected to be published in 2016.  Keep up with the expected changes here.


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.


It’s right if you and your organization want to eliminate or minimize risk to employees and anyone else who may be exposed to OH&S risks associated with its activities.

NQA has certified a wide range of organisations indifferent sectors including Jaguar Land Rover, Unilever and Veolia Water. It’s likely you will have some elements required by OHSAS 18001 already in place. We can help you build on what exists to provide a more cohesive management system to meet the requirements of the standard.

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.

“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 organisation.” Jaguar Land Rover

Process >


  • Application for registration is made by completing the OHSAS 18001 Quote Request Form. This provides information about your organisation so we can accuratelydefine 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).
  • Certification is issued by NQA and maintained through a programme of annual surveillance audits and a three yearly recertification audit.


Stage 1

The purpose of this visit is to confirm the readiness of the organisation for full assessment. The assessor will:

  • confirm that the OH&S management system conforms to the requirements of the standard
  • confirm its implementation status
  • confirm the scope of certification
  • check legislative compliance
  • produce a report that identifies any non-compliance or potential for non-compliance and agree a corrective action plan if required
  • produce an assessment plan and confirm a date for the Stage 2 assessment visit

Stage 2

The purpose of this visit is to confirm the quality management system fully conforms to the requirements of OHSAS 18001 in practice. The assessor will:

  • undertake sample audits of the processes and activities defined in the scope of assessment
  • document how the system complies with the standard
  • report any non-compliances or potential for non-compliance
  • produce a surveillance plan and confirm a date for the first surveillance visit

If the assessor identifies any major non-conformance, the organisation cannot be certified until corrective action is taken and verified.
