The OH&S management system contains the documented information the standard requires, plus whatever documented information the organization decides it needs for the system to be effective. How much is needed can vary with the size of the organization and the kind of activities, processes, products and services it has, with the need to show that legal and other requirements are met, with how complex its processes are, and with how competent its workers are.
This control maps to 17 controls across 13 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 17 it maps to, and the evidence behind each claim, over MCP and REST.
