The more than 100,000 organizations already compliant with OHSAS 18001 – the British forerunner to 45001 – might want to make the transition to 45001, since 18001 certification will stop in March 2021.
Publication of ISO 45001 comes approximately four years after the drafting process began – and around two years longer than it typically takes to draw up a new management standard. The proposal for a global occupational health and safety management standard was originally proposed in the mid-1990s. ISO 45001 draws on OHSAS 18001 – the former global benchmark for OHS – but it is a new and distinct standard, not a revision or update. 45001 is due to be phased in gradually over the next three years.
