Final answer:
If controls to reduce risk beyond your authority, escalate the issue to someone with necessary authority.
Step-by-step explanation:
If the controls necessary to reduce the level of risk to a level of "LOW" are beyond your level of authority to implement, you must escalate the issue to someone with the necessary authority.
This could be a supervisor, manager, or someone higher up in the organizational hierarchy who has the power to make the necessary changes. By escalating the issue, you ensure that it receives the attention and action it requires to mitigate the risk effectively.
