ISO 9001 and ISO 14001 are most widely used standards worldwide as quality management system and environment management system respectively. ISO 45001 is a recent release on occupational health and safety management system. Although all these three standards are revised in recent three years i.e. from 2015 to 2018, ISO 45001 is the latest release in 2018. Typically all three standards follow the same high level structure so it will be very easy for organizations looking to integrate these three standards or any two of them. In order to ease the process of integration, the course presents a comparison matrix or correspondence matrix on latest version of ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. The first three clauses are non-auditable and are there only for guidance purpose in all three ISO management system standards. Auditable clauses are from Clause 4 to Clause 10.
