The ISO 45001 Draft International Standard (DIS) for Occupational Health and Safety Management Systems (OHSMS) was published in February 2016. This entirely new ISO standard incorporates requirements present in the OHSAS 18001 international standard as well as in standards and guidelines published by the International Labour Organization (ILO). Ultimately, it is expected that the ISO 45001 standard will completely replace OHSAS 18001 currently implemented by many organizations globally to minimize occupational risks and enhance worker safety. The new ISO 45001 standard will be structured in a way that will facilitate migration from existing occupational health and safety management systems (such as OHSAS 18001 and ILO Occupational Safety and Health Convention, Protocol 2002) as well as integration with other ISO management systems (e.g., ISO 9001, 14001) that are part of an organization’s performance improvement processes.

The ISO 45001 standard was initially scheduled to be published in final form by late 2016. However, final publication has been delayed due to events occurring in the DIS review and comment period. The balloting results from the more than 70 voting countries in May 2016 for acceptance of the DIS was 71% “For” and 29% “Against.” Per ISO standard development provisions, if more than 25% of the votes indicate “Against,” the standard cannot move to the next stage of approval.

The International Committee ISO/PC 283 met in Toronto in June 2016 to discuss over 3,000 comments that were submitted during the ballot. While the number of comments was extremely large, there has been no indication from the ISO standards-setting body that any points raised will prevent ISO 45001 from being finalized. In fact, the Committee met again in October 2016 to review the remaining comments and finalize the second DIS, which is expected to be released in December 2016 or January 2017, with another vote expected in February or March 2017. The Final DIS will likely be approved in September 2017 with expected publication in December 2017.
