ISO 45001:2018 6.1.2.2: Assessment of OH&S risks and other risks to the OH&S MS
Set up, run and keep processes that assess the OH&S risks arising from hazards that have been identified, with regard to how effective the current controls are, and that assess other risks connected with setting up, running, operating and maintaining the OH&S MS.
This control maps to 15 controls across 8 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
