Risk assessment is a process of examining the work operation and determining what hazards are present and what is required to protect against the harm being realised. This activity will determine whether a risk exists or not, and what the nature of that risk is.

Control measures are those things that have been put in place to ensure that the work operation proceeds safely, i.e. without risk. For example, training, physical barriers, safe system of work and other prohibitions / instructions.

Identify is simple. Evaluate is to examine what is required of the control and to ascertain how effective it is in meeting the overall requirements for controlling the work operation.
