2.1.9. Hierarchy of Control
The primary purpose of conducting a risk assessment is to determine the requisite controls that will ensure the level of risk is as low as achievable or practical. A criterion for considering whether the risk is at a suitable level is referred to as the hierarchy of control – nominally five levels of control measure (Table 7).
