The impetus for the development of ISO 45001 came from the British Standards Institute (BSI), which proposed to ISO in 2013 that OHSAS 18001 be considered as the basis for an international standard. ISO agreed and established a committee to oversee its development. As the proposers, BSI took on the role of Secretariat to the new committee (ISO PC 283). The first meeting of ISO PC 283 took place in London in October 2013, where key decisions were made, for example, that the standard would contain the requirements and include interpretative guidance as an annex. The WG was established and further divided into Task Groups (TGs) to separate the workload into manageable sections, so that each TG could focus on one or more clauses of the draft standard
