Section 4 - Procedure

Responsibilities

(7) The Division of Facilities Management has governance of the electrical installation in all buildings, including the provision, maintenance, repair, alterations and additions to the electrical installation.

(8) No alterations or additions to the electrical installation including hardwired systems shall proceed without prior approval of the Division of Facilities Management.

(9) Where facilities or workplaces have no nominal person in charge, such as shared teaching spaces and lecture rooms, then the relevant Campus Services Manager, Division of Facilities Management shall be the person in charge for the purpose of this procedure.

(10) The organisational unit is responsible for:

  1. the safety of all electrical equipment under their control or within any space for which they are responsible;
  2. ensuring all electrical work is undertaken by an approved person or the Division of Facilities Management;
  3. ensuring electrical equipment is used and maintained in a safe manner; and
  4. ensuring any electrical equipment that requires inspection, is tested and tagged in accordance with work health and safety legislation, Australian Standard AS3760: In-service Safety Inspection and Testing of Electrical Equipment, and this procedure.

(11) Organisational unit heads/managers are responsible for approving the use of privately owned electrical equipment in non public areas of the University in accordance with this procedure, ensuring such equipment is assessed as safe and electrically tested and tagged if required.

(12) Where facilities are occupied by more than one work unit (shared facilities), all units are equally responsible for ensuring the electrical equipment is used and maintained in a safe manner as per this procedure. 

(13) Only approved persons are authorised to electrically inspect, repair, test and tag electrical equipment including extension cord sets and multiple outlet portable power boards.

(14) All users of electrical equipment have a responsibility to:

  1. visually inspect equipment for signs of damage prior to use;
  2. use the correct equipment for the task;
  3. report any electrical defects to a person in authority, and ensure that the item is tagged 'danger - unsafe, do not use', until the item is tested or repaired;
  4. not remove a flexible lead plug from the wall socket, by pulling the lead;
  5. always completely unroll an extension lead before using and never use an extension lead while it is coiled or wound around a drum;
  6. check that portable electrical equipment that has been electrically tested and tagged is still within the approved period; and
  7. ensure that electrical equipment is set up correctly and used safely in accordance with any relevant instructions accompanying the equipment and this procedure.

(15) If a user becomes aware that equipment or associated wiring may be in a dangerous condition, the equipment should be switched off and unplugged, providing it is safe to do so, and the organisational unit management notified immediately. The item must be clearly labelled 'Danger: Do Not Use' and include the person's name, date and contact details.
