Procedure

High Voltage (HV) Electrical System


5.1 No one within the OBU is authorised to undertake high voltage work.

Low Voltage (LV) Electrical System

5.2 The University LV Electrical System is controlled and managed by Estates & Campus Services (ECS). 

5.3 The following additional procedures will apply for those wishing to work on the LV Electrical system:

  • ECS Code of Practice for Electrical Safety must be followed for any works which Faculty or Directorates wish to undertake to the University low voltage electrical system.
  • ECS CoP for Electrical Safety states for “No Live Working” is to be carried out. In very exceptional circumstances, limited types of Live Working or Live Testing may be necessary and can be justified in line with the requirements of Regulation 14 of the Electricity at Work Regulations. Where this is the case such work can only be carried out when all of the suitable precautions (including where necessary the provision of suitable protective equipment) has been taken to prevent injury and under the direction of an AO/AP.
  • Fixed wiring installations (i.e. the single phase and three phase wiring plus associated equipment installed to or within the fabric of buildings) must be installed to the current edition of BS 7671 (the IET Wiring Regulations) and formally inspected and tested before being put into service and thereafter at intervals recommended by the Institution of Engineering and Technology (IET).
  • All work on fixed wiring installations must only be carried out by Estates staff or Estates approved contractors and all such individuals must be appropriately qualified and competent. All organisations appointed as approved electrical contractors must be registered with a recognised approval body (NICEIC / BAFE etc).
  • Requests for any alteration or addition to the OBU LV electrical system must be submitted via an ECS work order
  • Excavations must not take place over, or near to, live distribution cables without a breaking ground permit (permit to dig), which covers requirements for cable location and appropriate digging techniques, being in place. A breaking ground permit should be raised through made through the University’s permit system

5.3 Only a suitably qualified and/or competent person may work on or near electrical systems or equipment, especially those involved in design, construction and operation of electrical systems (including purpose-built research apparatus): those who do not possess the required knowledge or experience must be under an appropriate degree of supervision, having regard to the nature of the work.

5.4 Where circuits are to be isolated to enable safe working, they must be ‘locked off’ with a suitable clasp/pad-lock (or similar device) and safety notices applied to the isolated circuit(s) at the point of isolation. This should be supported by a suitable Permit to Work or so that any unplanned re-energisation of the isolated circuit(s) can be prevented.

5.5 Newly acquired electrical equipment must conform to CE/British Standard certification and marking requirements prior to being used on campus, be fit for purpose and free from latent defects. Each Faculty/Directorate is responsible for maintaining the appropriate asset information with regard to equipment and items which may require insurance inspections.

5.6 Electrical equipment which might be exposed to mechanical damage, effects of weather or wet, dirty, dusty or corrosive conditions must be appropriate for such environments by design, construction and installation.

5.7 Electrical equipment which might possibly be used in any potentially flammable or explosive atmosphere, including dusts, vapours or gases, must be of such construction (or appropriately protected) as to prevent danger arising from its use and such exposure.

5.8 Planned Preventative Maintenance (PPM) testing and inspections should be carried out on any electrical installations or equipment on a risk appropriate basis. Including insurance inspections, as appropriate.

5.9 Electrical equipment developed within an academic department solely for use in a research capacity must not be energised without having been visually inspected, electrically tested, formally risk assessed and approved by the Module Lead or some other competent member of Faculty or Directorate staff e.g. Head of Operations.

Portable Appliance Testing (PAT) 

5.10 ECS are responsible for undertaking PAT across the whole University. A risk assessment has determined the appropriate frequency of such testing.

5.11 Where a Faculty/Directorate undertakes PAT in addition to that which is completed by ECS, the testing must be risk assessed and a local code of practice must be in place. Staff completing the testing must be competent.

Training and competency

6.1 Staff, students or contractors working on electrical equipment, machinery or installations must be competent to do so. This includes modifications to, or repair of, electrical equipment. The level of competence required will depend on the work to be done, and should be derived from a risk assessment of the task/activity.

6.2 Competency may be on the basis of qualifications, experience, training, knowledge and skills. Individuals may need to be regularly re-assessed to ensure that their skills and knowledge remain up-to-date. People who cannot demonstrate competence should not be allowed to work unless they are supervised by someone who is.


6.3 For those undertaking portable appliance testing on behalf of Oxford Brookes one way of demonstrating competence is for staff to attend a recognised portable appliance testing course. For further details, please speak to the Health and Safety team.

Review

7.1 This procedure and associated CoP for Electrical Safety will be reviewed every three years or sooner if it is evident that changes are required.
