This course is designed to train persons who have been nominated by their sponsor to enable them to attain the Controller of Site Safety competence.

The COSS competence is required to be held by anyone who is required to set up a safe system of work on or near the line for a group (two or more people). A COSS can also carry out the duties of an IWA provided there is to medical restriction that would otherwise prevent this.
