Set up, run and keep a hazard identification process that is continuous and looks ahead. The process shall take into account: social factors and the way work is organized; activities that are routine and those that are not; incidents that have happened before; possible emergencies; people, including workers, contractors, visitors and others; how workplaces and equipment are designed; changes; and changes to legal requirements, whether actual or proposed.
This control maps to 22 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.
