Once risk priorities have been established, reducing or removing the risk they pose is the next key step. The Hierarchy of Control is an approach that involves working through a hierarchy, or order, of possible, control measures until an appropriate solution is reached.

Appropriate Control for Significant Hazards

Hazard control is the process of implementing measures to reduce the risk associated with a hazard.  Significant hazard control is the process of implementing measures to reduce the risk associated with significant hazard.  The control process must follow the control hierarchy, in order, as prescribed in health and safety legislation.  It is always important that any control measures do not introduce new hazards, and that ongoing effectiveness of the control is monitored.

1. Elimination. Remove the hazard completely from the work area.

2. Substitution. Replace the material or process with something less hazardous.

3. Isolation. Isolate the hazard by controlling or guarding it.

4. Engineering controls. Redesign equipment or work processes to reduce or eliminate risk.

5. Administrative controls. Promote safe practice through policies, processes, training and signage.

6. Personal Protective Equipment (PPE). Use personal protective equipment to minimise risk.

Starting with Step 1, each strategy is considered in turn. For example, can this be implemented, will it solve the problem? If this step is not sufficient to manage the hazard, move on to the next until a solution is identified.
