OHSAS 18001 Management systems for Health and Safety at Work

​​​​​​​​​​​​​​​​​​​​​​​Health and safety at work as standard practice

All kinds of organisations are becoming increasingly interested in reaching and demonstrating their solid implementation of Occupational Health and Safety (OHS) by controlling their risks, in accordance with their OHS policy and objectives. They do so against a background of increasingly demanding legislation, the development of economic policies and other measures to promote good HSW practices, and greater concern by parties interested in this matter.

OHSAS 18001​ specifies requirements for a management system that are designed to help an organisation control its HSW risks and improve its HSW performance.​

Implementing and certifying a OHSAS Management System allows companies:

  • To reduce the work accident rate and to increase productivity by identifying, assessing and controlling the risks associated with each job, and eliminating factors that cause accidents and illnesses at work.
  • To comply with legislation regarding accident prevention. By integrating this last aspect into the organisation's processes, it can reduce costs and administrative sanctions derived from non-compliance.
  • To promote a preventive culture by integrating accident prevention into the company's general system and increasing the commitment of all workers to the ongoing improvement of HSW.

The OHSAS Certification 18001 by AENOR is the perfect tool for companies who want to continually improve in the field of OHS.

As a result of the publication of ISO 45001, organisations certified in accordance with OHSAS 18001 have a 3-year period to migrate to the new standard, during which time the certifications will be recognised and remain in force.

ISO 45001 represents an improvement to occupational health and safety management by the company, whilse allowing for better integration of other management systems, such as ISO 9001 and ISO 14001, which, just like ISO 45001, use the structure of common, high-level requirements. This standard also places greater emphasis on risk management and the context in which the organisation operates, and reinforces the role of senior management in SGSST leadership as a relevant party in business strategy. In light of the above, companies that use Standard OHSAS 18001 will find that Standard ISO 45001 represents a real opportunity to integrate occupational health and safety into their general procedures.

It is recommended that a GAP ANALYSIS be performed to enable organisations to assess their situation and understand the level of preparation they will need with respect to the requirements set out in the new Standard ISO 45001.

As a consequence of the publication of ISO 45001, organisations certified in accordance with OHSAS 18001 have a 3-year period to migrate to the new standard, during which time the certifications will be recognised and remain in force.

This certification scheme is applicable to any type of organisation, regardless of the sector in which it operates.

AENOR offers clients the option of carrying out the Statutory Audit Occupational Risk Prevention Audit together with OHSAS 18001 certification in a single comprehensive process, leading to savings in audit times and, therefore, in costs.

  • The AENOR Certificate for Systems to Manage Health and Safety at Work.
