BS OHSAS 18001: Effective occupational health and safety

Safety at work is one of the most important assets in all industrial sectors – for both employees and employers. The obligation to protect health and life by taking adequate safety precautions and detecting potential risks in good time comes first of all. But occupational health and safety is much more than this and also has a sustainable impact on company profits by preventing costly sick leave and machine downtimes.

Since 2007, British Standard BS OHSAS 18001 has formed the basis for internationally-recognized occupational health and safety. However, it will soon be replaced by its successor, International Standard ISO 45001, and on 30 September 2021, existing certificates based on BS OHSAS 18001 will lose their validity. The deadline has recently been extended by 6 months due to the COVID-19 outbreak. Organizations certified according to BS OHSAS 18001 can change over to the new standard within the framework of a recertification or surveillance audit.   

Why occupational health and safety? The benefit to you.

  • Accidents at work are prevented and sick leave reduced
  • Your workforce is more motivated
  • You can be sure to fulfil statutory requirements and achieve legal compliance
  • High safety standards give you a competitive edge
  • Certification as part of an integrated management system helps to save costs and optimise the efficiency of your business Management

FAQs on the transition from BS OHSAS 18001 to ISO 45001

When and how will the transition from BS OHSAS 18001 to ISO 45001 take place?

The transition period will end on 30 September 2021. Then, as from 01 October 2021, all accredited certifications based on BS OHSAS 18001 will no longer be valid.

Certified companies and organizations have to change over to the new standard, ISO 45001, within the framework of a recertification or surveillance audit, and must also successfully implement the changed requirements.

Is initial certification according to ISO 45001 more cost effective than a changeover from BS OHSAS 18001 to ISO 45001?

For organizations of certain sizes, the additional time and costs can be less in a certification audit than in a recertification or surveillance audit. Please contact us in order to find out about your own particular case. 


What is the procedure for transfer from another certification company?

First the transfer audit is carried out and a certificate is issued based on BS OHSAS 18001. Soon after issuance of the certificate the changeover can be made to ISO 45001:2018 by means of an audit. The same rules for the extra time that is needed apply as for a transition in a recertification, surveillance or special audit. Organizations can also carry out the transfer with standard BS OHSAS 18001 and then migrate to ISO 45001 in the next surveillance audit.

How much extra time is needed for transition within the framework of a surveillance or recertification audit?

The time needed by an organization for transition to ISO 45001:2018 depends among other things on the maturity and effectiveness of the current OH&S management system. For this reason, performance of a gap analysis is urgently recommended in order to determine the internal need for action and to assign the necessary resources and the schedule.

The International Accreditation Forum (IAF) specifies the additional time needed for transition to ISO 45001 as one audit day. More time is needed for large and complex organizations.
