Electrical safety

Faulty electrical equipment can cause electric shocks and fires which may cause death, injury or damage to property (.pdf). It is vital equipment is regularly maintained so that it is safe to use.

You can identify the majority of potentially dangerous electrical equipment through simple visual checks (.pdf). If you have any concerns, do not use the equipment; switch it off if safe to do so and immediately contact the person responsible for electrical safety in that area or for that activity.

Persons responsible for areas where there is a potentially higher risk of electric shock may wish to display a Health and Safety Executive poster giving basic emergency advice.

You should report concerns to the Estates Management Helpdesk. Any electrical equipment that is suspected to be faulty must be labelled, 'DO NOT USE', taken out of use and kept secure until it can be examined by a competent person. This must be done so that other persons do not assume the equipment is safe to use.

All incidents, accidents or near-misses which involve a person coming into contact with electricity must be reported to Health and Safety, and an appropriate investigation carried out with the aim of preventing any recurrence.

Some types of dangerous occurrences may also need to be reported by HSAS under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations:

Dangerous occurrences - any explosion or fire caused by an electrical short circuit or overload (including those resulting from accidental damage to the electrical plant) which either results in the stoppage of the plant involved for more than 24 hours; or causes a significant risk of death.

You must dispose of surplus electrical equipment in an environmentally friendly manner and in accordance with consumer protection requirements. Find out more about the purchase, use and disposal of all work equipment.

A flowchart (.pdf) provides an overview of how to dispose of University owned, surplus electrical equipment.

Under the Waste Electrical and Electronic Equipment (WEEE) Regulations 2006, electrical and electronic waste must be disposed of responsibly and recycled where possible. This means that electrical or electronic equipment which cannot be repaired, is uneconomical to repair or is no longer wanted must not be put into landfill via normal waste bins. Equipment covered by these regulations will show a symbol, as shown on the right.

The means of disposal will depend on whether the item was purchased before or after 13 August 2005. See the University’s Waste and Recycling Policy for details. The Government provide information on environmental management waste regulations and retailer and distributor responsibilities.

How to dispose of items

For all campuses, contact the EMS Helpdesk

Reuse or resale of equipment

Electrical equipment which is no longer wanted but may be of value to others is subject to strict laws relating to the safety of goods under health and safety, consumer protection and product liability, as well as trading standards.

Electrical equipment, in a safe or defective condition, owned by the University must not be sold or given away free of charge. Printed, verbal or online advertisements for University equipment which is no longer wanted are also not permitted. This is because it is not possible to exclude liability under the Consumer Protection Act 1987 by means of any contract term or other provision. This in turn means the seller could be sued if a consumer or other person were injured as a result of defective equipment. Examples include unwanted computer or audio visual equipment, kitchen or workshop equipment.

Electrical equipment must either be responsibly disposed of according to WEEE Regulations or formally donated by the University to a registered charity. That organisation would then be legally responsible for the re-sale or use of donated equipment.

In exceptional circumstances, should a department or individual wish to sell equipment which is owned by the University for revenue purposes, they must seek professional advice on consumer protection requirements. They must contact the Insurance office to arrange appropriate product liability insurance and seek written approval to proceed from their Head of Department or person responsible for the equipment concerned.

High-value items

Where electrical equipment may have a high value, either as a single item or collective items, contact the  Central Procurement Unit who will advise whether and how any revenue might be generated or equipment potentially re-used by a third party. As a guide, a 'high value' would be an item/s worth around £5,000 or more or there may be an intrinsic rather than a financial value. As above, the same provisions for insurance and approval would apply.

Record keeping

Disposal of personally-owned items

You have a number of ways to recycle unwanted electrical equipment:

• you can ask the retailer if they'll take products back
• you can take old appliances to your local recycling centre
• you can arrange for your local authority to collect the equipment from your home (some local authorities provide a free collection service and others charge)
• you can arrange for an electrical retailer delivering new equipment to take away the unwanted one

For more information, Essex County Council have created an article on how to dispose of electricals.

• ESF's socket overload calculator.
• HSE guidance on electrical safety at work.
• Electrical safety for entertainers (.pdf).
• Electrical Safety Council - general advice on electrical safety.
• Association of British Theatre Technicians publications.
• HSE guidance on maintenance priorities in catering
• Glossary of terms (.pdf).

Dangerous equipment presents a serious risk of harm and will be removed where it is safe to do so, including:

• equipment in a poor state of repair, showing evidence of exposed inner cables, burning or overheating or cracked or broken housing
• equipment that has been made or adapted by someone without appropriate electrical knowledge/training
• travel adaptors that are not fused and/or do not have an earth connection
• travel adaptors with significant risk of contact with live parts: for example adaptors with removable backs or those multiple pin arrangements, where unused pins could become live
• equipment for which a safety warning/product recall has been issued for safety reasons

See examples of dangerous electrical equipment (.pdf)

If you have purchased a replacement power cable which is not from the same manufacturer as the equipment, you should use the 6-point safety check below, before turning on the power.

• Does it have insulation on the pins?
• Does it have a CE mark?
• Does it fit in the socket properly?
• Does it have a manufacturer’s brand name, model and batch number?
• Does it have the correct output voltage (V) for your device?
• Does it have the correct output current rating (mA) for your device?

The items below can produce significant heat which could start a fire or cause injury, and so are unsafe if used in certain locations. In addition, the way items are heated or cooked can produce fumes which could activate the fire alarm system.

Prohibited electrical items in University residences

Study bedrooms 

No equipment for heating, cooking, refrigeration or washing may be used in the study bedrooms of University-owned or administered accommodation, except with the prior written permission of the Head of Accommodation Essex.

Prohibited electrical equipment will be removed from study bedrooms where there is evidence such items have been used or where no authority to use has been obtained. Examples include:

• portable heaters (unless supplied or approved by the Accommodation Manager)
• cooking equipment such as stoves, toasters, sandwich makers, microwaves or microwave combination ovens, rice cookers or any equipment used for frying
• refrigerators (unless required for medical purposes and approved by Head of Accommodation Essex)
• washing machines
• halogen lamps
• electrical wax melters
• any similar equipment which can reach a high temperature

Residential kitchens

The following will be provided by the University for use in residential kitchens:

• ovens
• microwave ovens
• refrigerators
• electric kettles

A limited number of rice cookers or toasters can be used in kitchens provided the following conditions are met:

• they are purchased in the UK
• they have an annual portable appliance test (which can be arranged through the Estate Management Helpdesk)
• they are plugged directly into a wall socket

No other equipment for heating, cooking, refrigeration or washing may be used in kitchen areas unless approved by the Accommodation Manager and undergoes an annual portable appliance test. Please refer to the list under study bedrooms for examples.

Prohibited electrical items in non-residential areas

Non-residential areas include academic areas, study areas, offices, kitchenettes, workshops, laboratories etc. The only exception is use of cooking equipment in commercial kitchens. 

The following electrical items are prohibited from non-residential areas:

• portable heaters (unless supplied and approved by Estates and Campus Services)
• cooking equipment such as ovens or stoves, toasters, sandwich makers, microwaves or microwave combination ovens, rice cookers or any equipment used for frying

University health and safety inspections have found dangerous travel adaptors being used by employees and students, some of which were found to be unfused and others with exposed pins. Dangerous travel adaptors not only present an electrocution risk (which could potentially be fatal) but also have the potential to cause electrical equipment to overheat or spark and start fires.

Trading Standards in the United Kingdom have advised that travel adaptors need to meet the following requirements. They must:

• comply with BS5733 and preferably BS1363-3
• contain an appropriate fuse
• be designed so that it is not possible to insert one current carrying plug pin into the adaptor, whilst leaving the other exposed (see image):

University-approved travel adaptors, which have been checked against the above requirements, are available from Essex Essentials. Employees and students who require a travel adaptor are encouraged to purchase them from here. Adaptors can also be purchased from Everything Essex on Square 4 at the Colchester Campus.

Some posters have been produced to help with selecting safe travel adaptors:

• Electrical hazards from unsafe plug adaptors (.pdf)
• Choosing the right plug adaptor (.pdf)

Inspections

Inspections or checks of work, study or accommodation areas may identify electrical equipment which is prohibited or dangerous. Typically action may be taken by the Head of Department, Section/Business unit, the person responsible for the area, Estate Management Section, facilities management provider or the Health and Safety team.

One or more photographs may be taken to illustrate the circumstances or environment in which the electrical equipment was found. These could be sent to the appropriate responsible person for further investigation and/or to the owner to illustrate what was found.

Removal of items

Dangerous equipment presents a serious risk of harm and so will be removed where it is safe to do so. Prohibited items in non-residential premises may be removed. If it is not safe to remove the item, one of the University's electricians will be asked to attend and make sure the equipment is safe.

Owners of dangerous or prohibited items will be advised that the equipment must not be used. Reasonable attempts will be made to contact the owner, who will be advised of why the equipment is dangerous or prohibited and will need to confirm that they will not use the item if on University premises, before it is returned to them.

• Notice for removal of prohibited or dangerous electrical items (.docx)

Dangerous travel adaptors

If a student is found to be using a dangerous travel adaptor in University accommodation during room inspections, it will be replaced with a safe one and the student will need to stop using the unsafe adaptor.

• Choosing the right plug adaptor (.pdf)

Return of dangerous or prohibited items

The individual will need to complete a form like the one below when they collect the item/s, to ensure that the owner is aware that the prohibited and/or dangerous items must not be put back into use. The wording may need to be adjusted according to the circumstances. Retain the original, signed copy in case this needs to be referred to in future. A copy should be provided to the individual on request.

Further information

Please refer to the accommodation Terms and Conditions of Residence (.pdf) for more information on safety in student residences.

The following electrical equipment may be used in offices, staff common rooms and kitchenettes on all campus locations, provided an email is sent to the Estate Management Section (EMS) helpdesk to notify where these types of equipment are located:

• microwave ovens (not combination ovens)
• coffee makers incorporating pressure devices

The EMS electrical team will assess the installation. Approval is required as power capacity is limited in some areas and circuits must be checked to ensure that overloading does not occur. If the item is permitted, an employee in the relevant area must be nominated as responsible for the equipment and must ensure that:

• it has been inspected/tested in accordance with the University's Portable Appliance Testing (PAT) standard
• it is cleaned regularly to ensure good hygiene
• it is installed in a location which does not present a hazard to those using the room or a fire risk

The following items can be used in offices, staff common rooms and kitchenettes without reference to the Estate Management Section or approved facilities management provider:

• kettles
• coffee makers (except those incorporating pressure devices)
• refrigerators

These may be used provided:

• the equipment has been inspected/tested in line with the University's Portable Appliance Testing (PAT) standard
• appliances are installed in a location which does not present a hazard to those using the room
• in the case of refrigerators, they are defrosted at regular intervals to maintain energy efficiency

There has been a significant rise in the number of fires in the UK caused by faulty chargers for e-cigarettes and other electrical devices. Follow the advice below to reduce the risk of a fire, electrical shock or damage to your equipment when recharging e-cigarettes and mobile devices.

• Use the original charger supplied with your device.
• If you need a replacement or additional charger, purchase a genuine factory replacement.
• Avoid cheap unbranded replacements from the internet or market stalls.

Check out the London Fire Brigade's information on chargers, batteries and fire safety. 

When charging e-cigarettes

• Do not leave it charging for prolonged periods.
• Never leave it on to charge overnight.
• Do not leave it charging unattended.

Please note: the University’s no smoking policy also applies to the use of e-cigarettes. The use of e-cigarettes is prohibited wherever smoking is prohibited.
