Iso45001 certification is an alternative version of ISO18001 occupational health and safety management system certification standard. On March 30, 2016, the draft version of ISO / DIS 45001 occupational health and safety management system was officially released, marking that the formulation of ISO 45001 standard has entered the stage of public review. This draft standard basically describes all the necessary requirements of an occupational health and safety system. The review period of the draft standard is three months, during which each member of ISO participates in the review and gives feedback. If the result is positive, the subsequent final draft version will be appropriately updated based on the existing requirements in this version, and the official standard is expected to be released in the fourth quarter of 2016.
