1. Scope of Policy

Keele University recognises its responsibility to ensure that all employees and those contractors and suppliers engaged by Keele University, directly or via third parties, to work on its sites and premises comply with all relevant statutory requirements for the safe management, isolation and re-energisation of electrical systems owned and managed by the University. The University accepts its responsibility to take every reasonable precaution as outlined in The Electricity at Work Regulations 1989 to protect occupiers, users, contractors and visitors within the vicinity of the campus. Electricity can prove fatal, or can cause serious injury and burns, as confirmed by vast numbers of cases, all of which could have been prevented. It is these preventative measures that Keele University wishes to address across its portfolio for the protection of students, staff, contractors and visitors. The associated liability of such an fatality or injury, necessitates the need for clear, concise guidelines to be published, recommending measures to be taken to prevent injury or fatality within the buildings owned, managed or maintained by Keele University. Electrical services, in particular switch rooms, are the areas requiring close scrutiny regarding maintenance methods and procedures. The measures to be taken for our management of this risk are contained within this document.

2. Policy Statement

The University recognises and accepts its responsibility as an employer for providing, as far as reasonably practicable, a safe and healthy working environment for its employees. In addition, it will ensure, so far as is reasonably practicable, that persons other than employees, including students, visitors and contractors, are not exposed to risks to their health and safety. The University also requires employees to take reasonable care of their own health and safety, and that of other persons who may be affected by their acts or omissions at work. Employees are also required to co-operate with the University and any other person to enable them to meet their own statutory obligations. These rules are assembled to establish safe working practices for the protection of those whose specific role involves work on low voltage (exceeding extra-low voltage but not exceeding 1000V a.c. or 1500V d.c. between conductors, or 600v a.c. or 900V d.c. between conductors and Earth) electrical systems and equipment on Keele University sites and premises. The rules govern work associated with Keele University electrical systems and equipment, and apply to both Keele University employees and those contractors and suppliers engaged by Keele University, directly or via third parties, to work on its sites and premises. Note: Any work undertaken may also be governed by Keele University policies and safety rules other than those for electrical safety, such as those applying to general occupational health and safety matters and not least the requirement that work activities are subjected to risk assessment and safe system of work / method statement.

3. Legislation and Guidance

All persons who are, or who may be, concerned with the installation, control, operation and / or maintenance of any electrical equipment shall comply with the Keele University electrical safety rules, which observe the following statutory provisions: The Health and Safety at Work etc. Act 1974 The Management of Health and Safety at Work Regulations 1999 The Electricity at Work Regulations 1989 The Electricity Safety, Quality and Continuity Regulations 2002 The Control of Asbestos Regulations 2012 Personal Protective Equipment at Work Regulations 1992 Provision and Use of Work Equipment Regulations 1998 Construction (Design and Management) Regulations 2015 These persons must also comply with the requirements of BS7671 (as amended) – Requirements for Electrical Installations. Keele University - Responsibility The University recognises its responsibility to implement the regulations listed above and any other relevant policies, procedures or guidance notes . To comply with these legal duties, Keele University is obliged to:

i) Identify and assess sources of risk ii) Prepare a scheme for preventing or controlling the risk iii) Implement, manage and monitor precautions iv) Implement a safe system of working v) Keep records of the precautions implemented and do so for each of the

premises within the university’s control. vi) Appoint a person to be managerially responsible.

Statutory and Dedicated Legislation Applying to Electrical Systems a. Health and Safety at Work etc. Act 1974

The management have a duty to ensure that there is an appropriate regime for the design, installation and maintenance of electrical plant and systems. A proper system of work and adequate control measures are essential to conform with this Act.

b. Management of Health and Safety at Work Regulations 1999

These Regulations provide a broad framework for controlling health and safety at work. To comply with them the management must make a suitable and sufficient

assessment of risks to health and safety for its employees and others arising from work activities.

c. The Electricity at Work Regulations 1989

The Electricity at Work Regulations 1989 (as amended) came into force on 1 April 1990. The purpose of the Regulations is to require precautions to be taken against the risk of death or personal injury from electricity in work activities.

d. The Electricity Safety, Quality and Continuity Regulations 2002

The new Regulations specify safety standards which are aimed at protecting the general public and consumers from danger. In addition, the Regulations specify power quality and supply continuity requirements to ensure an efficient and economic electricity supply service for consumers.

e. The Control of Asbestos Regulations 2012 The Control of Asbestos Regulations 2012 (the Regulations) set minimum standards for the protection of employees from risks related to exposure to asbestos. Employers should also take account of people not directly employed by them but who could be affected by the work being done on asbestos (including employees of other employers, people occupying buildings, members of the public etc.).

In addition the following procedure documents and guidance should be referred to for information.

4. Rationale for Policy Electricity has many uses, the most common of which are light, power, heating (air and water) and ventilation. However electricity is extremely dangerous. Electrical danger is the risk of injury to persons from fire, electric shock, burns, arcing and explosion from the use of electrical energy. The lethality of an electric shock is dependent on several variables: Current - The higher the current, the more likely it is lethal. Since current is proportional to voltage when resistance is fixed (Ohm's law), high voltage is an indirect risk for producing higher currents. Duration - The longer the duration, the more likely it is lethal Pathway - If current flows through the heart muscle, it is more likely to be lethal. Voltage - In addition to greater current flow, higher voltages may cause dielectric breakdown at the skin, thus lowering skin resistance and allowing further increased current flow. All of the above factors can be mitigated with a robust, concise electrical safety policy and suitable training to all staff and contractors on the content of such policy.

5.1.10 Building Surveyors and Staff

Capital services staff and any consultants appointed by them shall be responsible for the effective design and management of all capital schemes including appropriate and comprehensive commissioning which is to be agreed with the Responsible Person (electrical) during the design stage. To comply with CDM Regulations, information about an existing system that is to be modified should be passed to the Building Surveyor, together with the operating criteria that have to be achieved for the system. This should detail installation and commissioning requirements. They will also be responsible for ensuring that plant and services are capable of meeting any increased demand where a system is extended and for the provision of as-fitted drawings at the time of handover, together with all commissioning data. No system will be accepted unless the Responsible Person (electrical) is agreeable. 5.2 Responsible Person / Deputy Responsible Person Training Requirements A Responsible Person (electrical), should possess adequate professional knowledge and with appropriate training, and should be appointed in writing by management to devise and manage the necessary procedures to ensure that electrical safety is not compromised at any time. The Responsible Person should be a manager or director, or have similar status and sufficient authority to ensure that all operational procedures are carried out in an effective and timely manner. The Responsible Person will be required to liaise closely with other professionals in various disciplines. Training should be every 1 year, unless significant changes are made to BS7671, The Electricity at Work Act, The Health and Safety at Work Act or any other policy, act or regulation that affects the way in which electrical isolation is carried out.

6. Isolation Procedures 6.1 Pre-work Inspection and checks. Before any work commences, it is imperative that all RAMS are submitted to the university and that all persons are checked as being a skilled person (electrically). A list should be kept and updated by the University of persons assessed as skilled, registered to work on the university systems. A check must be made with the RP that the correct point of isolation is being used. All test instruments should be checked to ensure that they are compliant with the requirements of GS38. Ensure that the following information is obtained and understood

The nature and extent of the work to be done

The area in which it is safe to work

Their own responsibilities for safety

The safety precautions in force

The asbestos information for the Site / Area 6.2 Objection to Instructions If a person has an objection on safety grounds to instructions received for work on, or the operation of, electrical plant, he shall make his objection known to his line manager. The manager shall consider the matter immediately, referring to the PEE if the matter cannot be otherwise resolved. 6.3 Access to LV Switchroom Only persons who are classified as Skilled Person (electrically) or persons who are in their direct supervision are allowed to enter university LV switchrooms. 6.4 Access to HV / LV Shared Switchroom Only persons who have passed the Appointed Persons HV course, HV Sub-station access course or are under direct supervision from an appointed person, may enter the University HV Switchrooms or sub-stations. 6.5 Lock out Kits, Proving Units, Test Lamps and Danger Notices In order to carry out the safe isolation of an installation or part thereof it will be necessary to use a voltage indicating device. HSE state clearly in guidance note GS 38 - Electrical test equipment for use by electricians that contact type voltage detectors and test lamps specifically designed to identify whether or not a voltage is present should be used for this purpose.

The use of multi-range instruments is not recommended as it is possible to select an inappropriate range setting; the leads may not be sufficiently robust; and the probes may have excessive bare metal exposed; all of which may possibly put the user in danger. Reliance on non-contact type voltage indicators is also not recommended for use as the sole means of confirming that a circuit or piece of equipment has been made dead. A wide range of contact type voltage indicating device are available. The general condition of a voltage indicator should be checked prior to each use and especially if the instrument has not been used for some time. Particular attention should be paid to the outer casing, leads, and probes. Only the minimum amount of probe should be exposed to allow the instrument to be used correctly. If a voltage indicator shows significant damage or deterioration, the voltage indicating device, or where appropriate, the component parts in question, such as tips and lamps, should be replaced before further use. The functionality of a voltage indicating device must be confirmed prior to each use. This can be achieved by checking on a known supply or perhaps more conveniently by using a proving unit. 6.6 Request To Isolate A request to isolate form must be filled in by the engineer and issued to the RP prior to any works commencing. 6.7 Sub Permit To Work A sub-permit to work must be filled in by the RP or assistant RP referencing the request to isolate prior to issuing a permit to work. 6.8 Permit To Work Once all the pre-work inspection and checks have been completed and a request to isolate has been received by the RP and a sub permit to work issued, the electrical system to be worked on must be isolated by the RP and a permit to work issued. The ‘LV Safe Isolation Procedure’ (Appendix 3) must be followed. A multi hasp lock must be used to lock off the equipment isolated with one padlock from the RP and the other padlock from the engineer. Each key must be kept with the respective person at all times. 6.9 Cancellation of Permit and Re-Energisation of Supplies Once all works to the electrical system have been completed, the RP must re-energise the supply and cancel the permit to work and sub-permit to work. No supply is to be re-

energised until inspection and testing and certification has been carried out in accordance with Part 6 of BS7671 (As amended). Before reconnection of the supply, as much downstream load as is reasonably practicable must be isolated as possible to reduce arcing or the possibility of flashover. 6.10 Isolation by Other E&D Trades The E&D plumbing and heating staff have received safe isolation training to allow them to

isolate boilers and pumps to allow removal/repair.

7. Live Working Procedures

IMPORTANT No work of any kind is to be carried out on LV equipment when the equipment

is live if the purpose of the work can be achieved with the power isolated. 7.1 Pre-work Inspection and checks. Before any work commences, it is imperative that all RAMS are submitted to the university and that all persons are checked as being a skilled person (electrically). A list should be kept and updated by the University of persons assessed as skilled, registered to work on the university systems. Ensure that the following information is obtained and understood

The nature and extent of the work to be done

The area in which it is safe to work

Their own responsibilities for safety

The safety precautions in force

The asbestos information for the Site / Area 7.2 Objection to Instructions If a person has an objection on safety grounds to instructions received for work on, or the operation of, electrical plant, he shall make his objection known to his line manager. The manager shall consider the matter immediately, referring to the PEE if the matter cannot be otherwise resolved. 7.3 Live Working Notes No work of any kind is to be carried out on LV equipment when the equipment is live if the purpose of the work can be achieved with the power isolated. If it is not possible to complete the work without energising the equipment, this will only be permitted if an AP has issued a PTW which will identify all risks and all measures to be taken to minimise the potential danger. 7.4 Live Testing Apart from Inspection and testing as defined in Part 6 of BS7671 (As Amended), live testing is permitted only in the following circumstances:

The use of approved equipment for the purpose of voltage detection on a live circuit, but only where it is a necessary part of the test involved. In such circumstances the

test equipment used should comply with HSE Guidance Note GS38 – Electrical Test Equipment for use by Electricians, and adequate precautions are to be taken to avoid access to the equipment under test by persons not involved with the testing.

Any test or inspection procedure, other than voltage detection on a live circuit, which is necessary to be undertaken live. The test or procedure is to be specifically authorised by an AP. The AP authorising such live testing must attend and remain present for the duration of the operation. In no circumstances may an AP authorise himself to do such tests.

7.5 Electricity at Work Regulations 1989 The AP / SAP shall not authorise live testing or inspection procedures unless he is satisfied that the requirements of Regulation 14 of the Electricity at Work Regulations are satisfied: No person shall be engaged in any work activity on or so near any live conductor (other than one suitably covered with insulating material so as to prevent danger) that danger may arise unless –

It is unreasonable in all the circumstances for it to be dead; and

It is reasonable in all the circumstances for him to be at work on or near it while it is live; and

Suitable precautions (including where necessary the provision of suitable protective equipment) are taken to prevent injury.

7.6 Limitation of Live Testing Part 6 of BS7671 (As Amended) It is university policy that live testing is not carried out to the furthest point of any circuit to establish a Zs reading. A calculated value should be inserted using the measured R1+R2 reading for the circuit added to Zdb (Zdb must be measured in accordance with section 8.4). The formula for the value to be inserted in the Zs value box is: Zs = Zdb + (R1 + R2)

Appendix 1 – Emergency Procedure

Loss of Supply

On experiencing a complete or partial electrical power loss inform estates helpdesk (01782 733134), security (01782 733004), the RP (Ash Hulme, 01782 733135) and the SRP(David Sanderson, 01782 734224).

Await confirmation from the ‘on site’ electrician of the extent of the problem.

On instruction from the RP or SRP, security shall evacuate the affected building(s) if necessary.

If the power loss is localised, E&D security team are authorised to attempt to reset MCB’s or RCBO’s up to and including 32A Single Phase. If this is not successful, the E&D electrical engineers must be informed.

Electric Shock

It may not be immediately clear, but if you think someone is suffering from electric shock, approach with extreme caution.

The first step is to separate the person from the source of electricity as quickly as possible. The best way of doing this is to turn off the supply, for example, by unplugging the appliance or by turning the supply off

If this isn’t possible, then try to remove the source of electricity from the person using a piece of insulating material, such as a length of wood.

NEVER touch the person receiving the electric shock, or you could suffer one too.

After removing the person from the source of electricity, if the person is unconscious call for an ambulance immediately. Only those with the necessary knowledge and skill should carry out first aid.

Where the person is conscious and seems well, it is still advisable to monitor their condition, as the effects of an electric shock may not be immediately obvious. In worst case conditions, an electric shock may lead to a condition known as electroporation, where cells within the body rupture, leading to tissue death. Additional problems might include deep-seated burns, muscle damage and broken bones.

Appendix 2 – Emergency Aid

1) Danger If you suspect someone has received an electric shock you must ensure all power sources are isolated before you can treat the casualty.

High Voltage

High voltage electricity has the ability to ‘jump’ or ‘arc’ up to distances of 18 metres or over. If faced with a casualty resulting from high voltage electricity: Do not approach! Stay at least 25 metres away from the casualty until the power has been switched off by an official agency i.e. Electricity Board / Estates Department.

Low voltage

If faced with a casualty who is in the process of receiving an electric shock you should: - Attempt to turn the power off at the mains. - Remove any cables/power tools etc., still in contact with the casualty.

Action to take - Insulate yourself from the ground with books / newspapers / rubber matting - Use an object of low conductivity i.e. a wooden broom or rolled up newspaper to push away the power source.

2) Response

To give your casualty the optimum chance of survival you must quickly assess their levels of response. A rapid assessment will allow effective treatment to be administered and will also allow for accurate information to be passed on to the ambulance service.

Check whether the casualty is conscious

1. Ask “hello, can you hear me” and call their name if you know it. 2. Ask in both the casualty’s ears to open their eyes. 3. Pinch an ear lobe or gently tap the shoulders. 4. Shout for HELP! 5. DO NOT move the casualty unless the environment or situation is dangerous.

3) Danger

Call for help If alone call for help. If someone responds to your call ask them to stay with you whilst you assess the Airway and Breathing. One of you should wait with the casualty whilst the other calls an ambulance. NB: If no-one responds do not leave the casualty but go on to assess the airway and breathing.

Calling the emergency medical services: 1. Lift the receiver and wait for a dialling tone. 2. Dial 999 in UK (112 in Europe) 3. The operator will ask you which service you require. Once you have stated ‘ambulance’ you will be connected to ambulance control. The operator will ask you a set of questions. DO NOT hang up at any stage of the conversation. The operator will terminate the call when appropriate. Inform KU Security (888) as they will direct the ambulance to the correct location. Isolate or cordon off the exposed, damaged or faulty electrical source if safe to do so. As soon as possible, after the casualty has been taken to hospital report the incident to the local supervisor. Give all information you can as an IRF needs to be completed for all accidents and incidents. Leave details about yourself so that you can be contacted should the need arise. Report defective equipment that caused the shock (if applicable), so that repairs can be made. RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995) 4) Airway and Breathing

For an unresponsive casualty open the airway

1. Look in the mouth to ensure there are no obvious obstructions. 2. Open the airway by lifting the chin and tilting the head back. This will free the tongue from the back of the throat.

3. If neck/spinal injury is suspected, put one hand on the stomach to feel if it rises and falls. This indicates normal breathing.

Assess for breathing 1. LOOK for the rise and fall of the chest. 2. LISTEN for sounds of breathing. 3. FEEL for air on your cheek. 4. Carry this out for up to 10 seconds.

Breathing normally

If breathing is present go straight to the Recovery Position section. Not breathing

If the casualty is not breathing normally, commence full Cardio-Pulmonary Resuscitation (CPR). If you are alone, leave the casualty at this stage and call for help. Return to the casualty and commence CPR (Cardio-Pulmonary Resuscitation). 5) Unconscious – Not Breathing

To commence CPR: For an unresponsive casualty

1. Ensure the casualty is on a firm, flat surface 2. Place your hands one on top of the other in the centre of the casualty’s chest 3. Compress the chest (up to a maximum depth of approximately 4-5cm) 30 times at a rate of 100 compressions per minute. The compressions and releases should take an equal amount of time 4. After 30 compressions, open the airway again using head tilt/chin lift 5. Seal the nostrils with your thumb and forefinger. 6. Blow steadily into the mouth until you see the chest rise, take about a second to make the chest rise. It is advisable to have Resuscitation Equipment at this stage such as a face shield. 7. Remove your mouth to the side and let chest fall. Inhale some fresh air, when breathing for the casualty 8. Repeat so you have given 2 effective rescue breaths in total 9. If chest does not rise after the second breath, go back to 30 compressions then try again with 2 breaths. 10. Return your hands to the correct position on the chest and give a further 30 chest compressions.

Continue with CPR until: - The casualty shows signs of recovery - Emergency services arrive - You become exhausted and unable to continue - The situation changes and you are now in immediate danger. 6) Defibrillation

Use an AED (Automatic External Defibrillator) if available and follow prompts. 7) Recovery Position

If the casualty is unconscious and breathing normally, turn the casualty into the recovery position. - The recovery position is used when a casualty is unconscious and breathing. - The recovery position allows the head to be placed tilted back and down. This stops the tongue from blocking the airway and will allow any vomit and fluid to drain from the mouth.

If the casualty is breathing normally

1. Check for any other obvious injuries. 2. Remove sharp objects from pockets. 3. Turn the casualty into the recovery position. 4. Place the nearest arm at a right angle to the body. 5. Draw the furthest arm across the chest and place the back of the hand across the cheek. 6. Keep this here whilst you raise the furthest leg by grasping the top of the knee. 7. Gently pull on the knee so that the casualty pivots over onto their side facing you. 8. The casualty should be fully over and stable. 9. Re-check the airway, breathing and circulation. 10. Draw up the leg at a 90 degree angle. 11. Check for continued breathing. 12. Call the emergency medical services:

1. Lift the receiver and wait for a dialling tone. 2. Dial 999 in UK (112 in Europe) 3. The operator will ask you which service you require. Once you have stated ‘ambulance’ you will be connected to ambulance control. The operator will ask you a set of questions. DO NOT hang up at any stage of the conversation. The operator will terminate the call when appropriate. 4. Inform KU Security (888) as they will direct the ambulance to the correct location

8) Burns Exposure to electricity can cause burns to the skin and, in severe cases, internal organs. In such cases the electricity may, for example, enter via a hand and leave via the feet causing ‘entry’ and ‘exit’ burns.

Conscious casualties

Cool burns for a minimum of 10 minutes under cold water.

Unconscious casualties

Cool the burn with wet dressings after placing them in the recovery position. DO NOT

- Burst any blisters - Apply adhesive dressings - Remove damaged skin - Apply ointments/creams - Cover with ‘fluffy’ dressings - Affix dressing too tightly - Apply butter/fats/margarine - Remove damaged clothing - Apply ice.

9) Other Injuries

Muscle spasm/seizures

These may be present for some time after the exposure to electricity and indicate a seriously ill casualty.

Action in the event of a major seizure

1. The casualty will almost definitely collapse during a major seizure. Try to control the fall. 2. Ensure the safety of the casualty by removing any objects that may cause injury if they are struck. 3. Place padding under the head of the casualty. Improvise if necessary by using clothing. 4. DO NOT place anything in the casualty’s mouth. 5. Loosen any clothing that may restrict the airway. 6. When the seizure has subsided: 7. Check the casualty’s Airway, Breathing and Circulation (ABC). 8. If unconscious and breathing normally or semi-conscious, place the casualty in the recovery position (see above). Perform CPR if not breathing. 9. Can also put a blanket over casualty to preserve modesty, also time the seizure. 10. Reassure the casualty whilst continuing to monitor the ABC and any other injuries.

Casualties with no apparent injury: If no injury is present and the casualty appears well, it is still advisable to take the casualty to a hospital or medical facility for a check up, as certain organs/systems within the body may be affected several hours after a shock.

Appendix 12 – Temporary Connections to Keele Network

Introduction

The following appendix provides guidance on the safe use of electrical appliances and means of providing electricity to such within the external areas of the campus and within university buildings. This appendix, and any / all others associated with the event MUST be adhered to. Failure to do so may result in the event being terminated due to safety concerns. Throughout the year, several indoor and outdoor events are held at Keele University. These events inadvertently involve some element of electrical connection to the Keele network. These are usually appliances and/or extension leads plugged into one of many feeder pillars installed around the campus for the purpose of temporary events or small scale generators to supply individual items of equipment.

Keele University recognises that some installations are exposed to many differing and onerous circumstances, as they are often frequently installed, dismantled, moved to a new location then installed and operated again.

To compound the problem, such installations are frequently exposed to the elements and are frequented by the general public, staff, students and children. There is also a risk, as this is an open campus, of unauthorised access.

The equipment must function without compromising safety. The installation has to, therefore, be fit for purpose and designed to cope with ever changing conditions.

The fact that an installation is temporary should mean that the installation standards are any less than that of a fixed installation. Indeed, due to the conditions listed above, the installation frequently has to be of a higher standard than that of a fixed installation.

Section 711 and Section 740 (BS 7671:2008 + A3:2015) are particularly relevant to these types of installations. The requirements of these sections must be given special consideration but must be read alongside the other requirements of BS7671:2008 (As Amended).

Process of application for connection of appliances for events General The use of electrical appliances for events shall be subject to approval by Keele University Estates & Development Directorate (Keele University E&D Directorate). The following process shall be followed:- Step 1 – Identify preferred location of the event / area requiring electricity.

Step 2 – Produce a plan showing location and size of all parts of the event. Plans can be obtained from the Keele University E&D Directorate team. All fixed structures (Marquees / tents etc) and large free standing equipment (tables etc) should be identified on the plan. Step 3 – Identify a list of electrical appliances to be used, and their ratings. The list should include all lighting within Marquees, DJ equipment, catering equipment. The rating will be stamped on the equipment. The voltage (230V or 400V) and power rating (Watts / W / kW) need to be provided. Portable Appliance Test certificates for all equipment to be connected must be provided. Step 4 – Determine a method of electrical distribution i.e. 230V 13A extension leads or a ‘commando’ temporary distribution unit system. Where a large marquee is being provided by an external company it will generally be a ‘commando’ temporary distribution system. These will generally need to be provided and installed by the Marquee company. Where events are within a building, generally 230V 13A extension leads will be used. Extension leads can be obtained and installed by Keele University E&D Directorate (this is generally a chargeable service). Step 5 – Note any nearby electrical connection points and make note of the reference. This is only relevant for external events. Step 6 – Provide the above information / request to Keele University E&D Directorate a minimum of 4 weeks prior to event date. Step 7 – Final scheme to be agreed with Keele University E&D Directorate. Step 8 – Keele University E&D Directorate to carry out pre-use electrical tests of the connection points and carry out final connection to KU infrastructure. Step 9 – Any electrical issues during the event during normal working hours are to be reported to Keele University E&D Directorate Helpdesk, any issues out of normal working hours are to be reported to KU Security. Any electrical issues affecting KU infrastructure shall only repaired by Keele University E&D Directorate operatives. Tampering by the event organisers / operators shall not be permitted. Any electrical issues caused by equipment within the event must be disconnected and removed from service; until this is done re-energisation of supplies will not be permitted.

Pre-use tests of external electrical connection points Keele University E&D Directorate shall undertake the following tests on the day prior to the event and carry out any repairs required: - Functional and mechanical test of all RCD’s / RCBO’s. - Earth fault loop impedance test at the main isolator. - Visual inspection. Pre-use tests of internal electrical connection points Keele University E&D Directorate shall undertake the following tests on the day prior to the event and carry out any repairs required: - Functional test of all RCD’s / RCBO’s. - Visual inspection. Location of external electrical connection points General The external electrical connection point shall be discussed with Keele University E&D Directorate to determine the most suitable area of supply. Connections to Feeder Pillars

All connections to feeder pillars must be carried out by E&D electrical staff. No supplies are to be energised until Portable Appliance Testing (PAT) certificates have been verified for all items of equipment to be connected to the Keele network.

It is imperative that all items of equipment are of a suitable IP and IK rating for the installation method and installation location.

Any trailing leads from feeder pillars must be routed in such a way to avoid, so far as is reasonably practicable, crossing walkways or roads. Where this is unavoidable, the cables must be suitably secured and protected to prevent damage to the cables and avoid any trip hazards.

Security of Feeder Pillars All external electrical connection points shall be locked via use of an KU Electrical ASSA suite lock. All new external connection points shall be provided with a ‘cat flap’ for connection of trailing

leads, the ‘cat flap’ shall include a weatherproof seal and be secured by means of a hasp and staple and an KU Electrical ASSA suited padlock. Keys shall be retained by Keele University E&D Directorate. Keys shall not be issued to the Event organisers / operators. Electricity Consumption Electricity will generally be provided free of charge, however dependant on the type of event and anticipated consumption, there may be a charge. Use of Generators on Campus General Generators are strictly forbidden on campus, except without express permission of Keele University E&D Directorate. Generators shall not be permitted within a building. Generators shall only be considered for external events where there is not a local electrical power supply, and the event cannot reasonably be located near to a local electrical power supply. Process for application of use of a generator The following process shall be followed: Step 1 – Identify preferred location of the generator and produce a plan. The generator should be located in a position easily accessible by the delivery company. The generator should be positioned such that the noise, heat and fumes do not cause disruption to the general activities of the University. Plans can be obtained from the Keele University E&D Directorate team. Step 2 – Identify the generator electrical size. Identify a list of electrical appliances to be used, their ratings and anticipated operational time. This list will enable the supply company to suitably size the generator and any external fuel tanks as needed. Step 3 – Identify re-fuelling / fuel storage / supply requirements.

The use of plastic fuel cans shall not be permitted onsite. Where a petrol generator up to 4kVA used metal fuel cans securely stored may be used to re-fill the generator. Re-filling must be carried out with the generator OFF and COLD. Where generators above 4kVA are used onsite and additional fuel is envisaged a static plumbed in fuel tank must be provided. Fuel must be securely stored and away from naked flames/ heat. Step 4 – Determine a method of electrical distribution i.e. 230V 13A extension leads or a ‘commando’ temporary distribution unit system. Where a large marquee is being provided by an external company it will generally be a ‘commando’ temporary distribution system. These will generally need to be provided and installed by the marquee company. Step 5 – Provide the above information / request to Keele University E&D Directorate a minimum of 4 weeks prior to event date. Step 6 – Final scheme to be agreed with Keele University E&D Directorate. Step 7 – A copy of the generator test certificates are to be provided to Keele University E&D Directorate prior to the start of the event. Step 8 – Any electrical issues during the event are to be rectified by the generator hire company. Keele University E&D Directorate can provide assistance if required, however will be chargeable. Generator Types Portable Petrol Generators up to 10 kVA Manufacturers’ guidelines / instructions must be followed at all times. Never re-fuel the generator when it is running or the engine is hot. Do not use these generators to power computers or similar electronic equipment without the use of surge arrestors. Class II electrical appliances only shall be used with this type of generator. Portable Petrol Generators up to 10 kVA with an earth connection Manufacturers’ guidelines/ instructions must be followed at all times. Never re-fuel the generator when it is running or the engine is hot.

Do not use these generators to power computers or similar electronic equipment without the use of surge arrestors. Class I and Class II electrical appliances may be connected to this type of generator. The generator must either include a 30mA RCD, or the extension leads taken from the generator must include a 30mA RCD. The generator must be earthed using a suitable earth rod. Before any earth rod is installed the area must be CAT scanned, the service drawings checked and a permit to dig completed. CAT scanning must only be carried out by suitably trained and competent operatives. Under no circumstances is any earthing conductor from a portable generator set to be connected to the Keele network to obtain an earth path. Test certificate must be provided to Keele University E&D Directorate prior to the start of the event. The earth connection must be a maximum of 100 Ohms. Generators larger than 10kVA Manufacturers’ guidelines / instructions must be followed at all times. The generator must be earthed using a suitable earth rod. Before any earth rod is installed the area must be CAT scanned, the service drawings checked and a permit to dig completed. CAT scanning must only be carried out by suitably trained and competent operatives. Under no circumstances is any earthing conductor from a portable generator set to be connected to the Keele network to obtain an earth path. Test certificate must be provided to Keele University E&D Directorate prior to the start of the event. The earth connection must be a maximum of 100 Ohms. All generator outlets must incorporate a 30mA RCD. Class I and Class II electrical appliances may be connected to this type of generator. Do not use these generators to power computers or similar electronic equipment without the use of surge arrestors. Re-fuelling shall be via a plumbed in external fuel tank, or via a fuel management service provided by the generator hire company only. The generator shall be housed within an acoustic enclosure, the access flaps shall be closed and locked during operation. An accessible emergency stop button must be provided on the external face of the enclosure and operable without the need for tools or keys.

Where the generator is positioned on grass protection shall be provided. Use of Internal Power Supplies / Outlets For Events General Where rooms within University buildings are used for events, the event organiser must follow the procedure earlier in this appendix. This is to ensure that Keele University E&D Directorate have the opportunity to review the appliances to be connected and the available electrical infrastructure to ensure that the infrastructure is not unintentionally overloaded. Where extension leads are required these can be provided and connected by Keele University E&D Directorate department. This is a chargeable service. Electricity will generally be provided free of charge, however dependant on the type of event and anticipated consumption, there may be a charge.
