All 240 volt and 415 volt tools/equipment and electrical leads must be inspected and tagged prior to first use and at three monthly intervals by a qualified electrician. Earth leakage, residual current devices (RCD's) should be tested every month.

All items tested should carry a test tag color coded to indicate whether it is 'current' as follows:

• RED: JANUARY TO MARCH
• GREEN: APRIL TO JUNE
• BLUE: JULY TO SEPTEMBER
• YELLOW: OCTOBER TO DECEMBER

Tags should have a valid test date (that is within the period) and the electrician's registration number.
