Prioritizing hazards

Answer:

There is no requirements in OHSAS 18001 that define how to prioritize implementation of operational controls, but basically there are two approaches. You can either start with the controls that are the easiest to implement, such s administrative controls (i.e. writing work instructions), or you can start with the controls that address the most severe consequences regardless of the effort needed to implement them.

Keep in mind that some of the operational controls are mandated by law and they should be implemented first, without any delay.
