13 June 2016:

The much anticipated ISO 45001 standard has been delayed following members of the ISO committee voting to ‘disapprove’ the first draft. In order to get past the DIS (Draft International Standard) stage, you need to have two thirds of the committee giving it the thumbs up and less than one quarter voting against. In the recent ballot 71% were in favour, 28% against and 1% abstained, therefore the draft was not accepted and did not gain approval.
During the vote, over 3000 comments were made by members for consideration. The technical committee will now draft DIS2 for further consideration and ballot.
It now looks very likely that the official publication of the ISO 45001 standard will be delayed from 4th Quarter of 2016 to approximately 1st Quarter of 2017.
