Electrical Installations – Risk Assessment

It is important that electrical contracting businesses involved in commercial and industrial installations have a set of documented principles and procedures for working on, or near low-voltage electrical equipment, and in particular, for the commissioning of new works.

This is to ensure that there is no risk of injury to non-electrical persons or visitors on site as well as your employees following the energising of a new main switchboard or distribution switchboard.

Where an installation has been energised and the electrical installation is not fully completed, it is also important that correct procedures are undertaken in regards to circuit isolation and tagging. It is vital that any incomplete circuits are either correctly terminated or disconnected from the switchboard and terminated. Placing tape over a circuit breaker toggle is not acceptable.

The Australian Standard AS/NZS 4836:2001 Safe working on low-voltage electrical installations provides guidance on risk assessments.
