OHSAS 18000 is an international occupational health and safety management system specification. It comprises two parts, 18001 and 18002 and embraces a number of other publications.

OHSAS 18001 is an Occupation Health and Safety Assessment Series for health and safety management systems. It is intended to help an organizations to control occupational health and safety risks. It was developed in response to widespread demand for a recognized standard against which to be certified and assessed.

Who Created OHSAS:

OHSAS 18001 was created via a concerted effort from a number of the worlds leading national standards bodies, certification bodies, and specialist consultancies. A main driver for this was to try to remove confusion in the workplace from the proliferation of certifiable OH&S specifications.

The participants were as follows:

  • National Standards Authority of Ireland.
  • Standards Australia.
  • South African Bureau of Standards.
  • British Standards Institution.
  • Bureau Veritas Quality International.
  • Det Norske Veritas.
  • Lloyds Register Quality Assurance.
  • National Quality Assurance.
  • SFS Certification.
  • SGS Yarsley International Certification Services.
  • International Safety Management Organisation Ltd.
  • Standards and Industry Research Institute of Malaysia.
  • International Certification Services.

Benefits – How Can OHSAS Help?

The OHSAS specification is applicable to any organisation that wishes to:

  • Establish an OH&S management system to eliminate or minimise risk to employees and other interested parties who may be exposed to OH&S risks associated with its activities.
  • Assure itself of its conformance with its stated OH&S policy.
  • Demonstrate such conformance to others.
  • Implement, maintain and continually improve an OH&S management system.
  • Make a self-determination and declaration of conformance with this OHSAS specification.
  • Seek certification/registration of its OH&S management system by an external organisation.

What are the key features of OHSAS 18001:2007?

  • Great emphasis placed on “Health”
  • Alignment with ISO 14001:2004 throughout the standard to facilitate integration.
  • Compatibility with ISO 9001:2000.
  • Reference to PDCA cycle.
  • “Evaluation of Compliance” requested as per ISO 14001:2004.
  • People involvement in establishing the system and investigation of incidents.
  • Suitability for management system certification

OHSAS 18001 standard be integrated with other management systems?

OHSAS 18001 has been developed to ensure the compatibility with the ISO 9001 (Quality) and ISO 14001 (Environmental) management systems standards, in order to facilitate the integration of quality, environmental and occupational health and safety management systems by organizations, should they wish to do so.

The overall structure of the standard is similar to other relevant standard and many key requirements are common to all systems (e.g. policy, objectives, document control, internal auditing, management review, corrective and preventive actions)

Such integrated standardization approach allows certification bodies to provide organizations with Integrated Management System certification including all the three major standards for Quality, Environment, Health and Safety.

Who does the OHSAS 18001 standard apply to?

The OHSAS Standard applies to any organization that wishes to

  • Support and promote good OH&S prctices.
  • Minimize safety risks in the work environment.
  • Ensure the proper deployment of its OH&S policy and the achievement of objectives.
  • Introduce a common language for health and safety within the organization.
  • Establish, deploy, monitor and improve the OH&S management system.
  • Demonstrate OHSAS conformance to Stakeholders.
  • Achieving the OH&S management system certification by a third party certification body.

The OHSAS 18001 effective implementation requires a clear management structure with clearly defined authority and responsibility, measurable objectives for improvement, a systematic approach to risk assessment and measurable results. This includes the monitoring of health and safety management failures, auditing of performance and review of policies and objectives.

How to get OHSAS 18001 certification?

The management certification process follows the following steps:

Stage 1- the purpose of this visit is to determine the organization’s readiness for a full assessment.

The assessor will:

  • Audit the organization’s management system documentation.
  • 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.
  • evaluate if the internal audits and management review are being planned and performed and that the management system implementation is ready for Stage 2 Audit.
  • produce a report that identifies any non-compliance or potential for non-compliance and agree a corrective action plan if required.
  • produce an audit plan and confirm a date for the Stage 2 assessment visit

Stage 2 – this Audit shall take place at site and aim to confirm if the management system complies with the requirements of OHSAS 18001 and the internal documentation.

The Auditor shall verify:

  • the conformity to all requirements of the applicable management system standard or other normative document.
  • performance monitoring, measuring, reporting and reviewing against key performance.
  • objectives and targets (consistent with the expectations in the applicable management system standard or other normative document).
  • the management system and performance as regards legal compliance.
  • the effective implementation of the risk management approach.
  • the operational control of the processes.
  • the internal auditing and management review

The auditor shall

  • report any non-compliances or potential for non-compliance.
  • produce a surveillance plan and confirm a date for the first surveillance visit

If the Auditor identifies any critical or major non-conformance, the organization cannot be certified until corrective action is taken and verified.
