Absolutely NO!. Those 3 Steps of Hazard Management Control is not tools to stop and eliminate the hazards.
You may reduce or isolate the hazard in order not to expose the worker. But it will never eliminate the hazard it self as long as the source is still exist. As far as I know, There is no workplace that 100% free from hazard source. So, what should we do is maximize the effectiveness of hazard management. From the first step, engineering control, administrative control and the last one,...using Personal Protective Equipment (PPE). But Remember (again), those 3 steps is not eliminate the hazard(s) and its source. But only isolate in order not to reach you and your worker.
