      3. RISK MANAGEMENT
The following details the preliminary assessment of site hazards likely to be encountered, the level of risk associated with each, and the control proposed. Note that the risk level is the level of assessed risk without the controls in place. The controls listed have been determined as being
appropriate in reducing the risk to a level that is acceptable.
The hierarchy of control has been utilised to ensure that the highest practicable level of protection and safety is selected:
