Hierarchy of controls
Controlling the hazard by implementing the most effective hazard controls using
the “hierarchy of control” principle:
› eliminate the hazard
› if it is not possible to eliminate the hazard, isolate the personnel from the
hazard for example, by providing a barrier between the hazard and the worker or
› if elimination or isolation methods are not practicable, (or, if the hazard still
exists after elimination and isolation methods have been used), minimise the
hazard by implementing controls that minimise personnel exposure to the
hazard; and review the controls regularly to ensure that they are working as
planned.
